-#### Pick List
-
-When all material has been allocated someone has to pick all things from the warehouse.
-In case you need a printed pick list you can use the following template. This it just the
-table. All other info and CSS has been left out for simplicity. Please have a look at the
-BOM report for details.
-
-{% raw %}
-```html
-<table class='changes-table'>
-  <thead>
-    <tr>
-      <th>Original IPN</th>
-      <th>Allocated Part</th>
-      <th>Location</th>
-      <th>PCS</th>
-    </tr>
-  </thead>
-  <tbody>
-  {% for line in build.allocated_stock.all %}
-    <tr>
-      <td> {{ line.bom_item.sub_part.IPN }} </td>
-      {% if line.stock_item.part.IPN != line.bom_item.sub_part.IPN %}
-        <td class='chg'> {{ line.stock_item.part.IPN }} </td>
-      {% else %}
-        <td> {{ line.stock_item.part.IPN }} </td>
-      {% endif %}
-      <td> {{ line.stock_item.location.pathstring }} </td>
-      <td> {{ line.quantity }} </td>
-    </tr>
-  {% endfor %}
-  </tbody>
-</table>
-```
-{% endraw %}
-
-Here we have a loop that runs through all allocated parts for the build. For each part
-we list the original IPN from the BOM and the IPN of the allocated part. These can differ
-in case you have substitutes or template/variants in the BOM. In case the parts differ
-we use a different format for the table cell e.g. print bold font or red color.
-For the picker we list the full path names of the stock locations and the quantity
-that is needed for the build. This will result in the following printout:
-
-{% with id="picklist", url="report/picklist.png", description="Picklist Example" %} {% include "img.html" %} {% endwith %}
-
-For those of you who would like to replace the "/" by something else because it is hard
-to read in some fonts use the following trick:
-
-{% raw %}
-```html
- <td> {% for loc in line.stock_item.location.path %}{{ loc.name }}{% if not forloop.last %}-{% endif %}{% endfor %} </td>
-```
-{% endraw %}
-
-Here we use location.path which is a query set that contains the location path up to the
-topmost parent. We use a loop to cycle through that and print the .name of the entry followed
-by a "-". The foorloop.last is a Django trick that allows us to not print the "-" after
-the last entry. The result looks like here:
-
-{% with id="picklist_with_path", url="report/picklist_with_path.png", description="Picklist Example" %} {% include "img.html" %} {% endwith %}
-
-Finally added a `{% raw %}|floatformat:0{% endraw %}` to the quantity that removes the trailing zeros.

-### Default Report Template
-
-A default *BOM Report* template is provided out of the box, which is useful for generating simple test reports. Furthermore, it may be used as a starting point for developing custom BOM reports:

-title: Build Order Report
----
-
-## Build Order Report
-
-Custom build order reports may be generated against any given [Build Order](../build/build.md). For example, build order reports can be used to generate work orders.
-
-### Build Filters
-
-A build order report template may define a set of filters against which [Build Order](../build/build.md) items are sorted.
-
-### Context Variables
-
-In addition to the default report context variables, the following context variables are made available to the build order report template for rendering:
-
-| Variable | Description |
-| --- | --- |
-| build | The build object the report is being generated against |
-| part | The [Part](./context_variables.md#part) object that the build references |
-| line_items | A shortcut for [build.line_items](#build) |
-| bom_items | A shortcut for [build.bom_items](#build) |
-| build_outputs | A shortcut for [build.build_outputs](#build) |
-| reference | The build order reference string |
-| quantity | Build order quantity (number of assemblies being built) |
-
-#### build
-
-The following variables are accessed by build.variable
-
-| Variable | Description |
-| --- | --- |
-| active | Boolean that tells if the build is active |
-| batch | Batch code transferred to build parts (optional) |
-| line_items | A query set with all the build line items associated with the build |
-| bom_items | A query set with all BOM items for the part being assembled |
-| build_outputs | A queryset containing all build output ([Stock Item](../stock/stock.md)) objects associated with this build |
-| can_complete | Boolean that tells if the build can be completed. Means: All material allocated and all parts have been build. |
-| are_untracked_parts_allocated | Boolean that tells if all bom_items have allocated stock_items. |
-| creation_date | Date where the build has been created |
-| completion_date | Date the build was completed (or, if incomplete, the expected date of completion) |
-| completed_by | The [User](./context_variables.md#user) that completed the build |
-| is_overdue | Boolean that tells if the build is overdue |

-| quantity | Build order quantity (total number of assembly outputs) |
-| completed | The number out outputs which have been completed |
-| reference | Build order reference (required, must be unique) |
-| required_parts | A query set with all parts that are required for the build |
-| responsible | Owner responsible for completing the build. This can be a user or a group. Depending on that further context variables differ |
-| sales_order | References to a [Sales Order](./context_variables.md#salesorder) object for which this build is required (e.g. the output of this build will be used to fulfil a sales order) |
-| status | The status of the build. 20 means 'Production' |
-| sub_build_count | Number of sub builds |
-| sub_builds | Query set with all sub builds |

-| title | The full name of the build |
-| description | The description of the build |
-| allocated_stock.all | A query set with all allocated stock items for the build |
-
-As usual items in a query sets can be selected by adding a .n to the set e.g. build.required_parts.0
-will result in the first part of the list. Each query set has again its own context variables.
-
-#### line_items

 Label templates are written using a mixture of [HTML](https://www.w3schools.com/html/) and [CSS](https://www.w3schools.com/css). [Weasyprint](https://weasyprint.org/) templates support a *subset* of HTML and CSS features. In addition to supporting HTML and CSS formatting, the label templates support the Django templating engine, allowing conditional formatting of the label data.

-
-To print multiple part labels, select multiple parts in the part table and select the *Print Labels* option.
-
-### Context Data
-
-The following context variables are made available to the Part label template:
-
-| Variable | Description |
-| -------- | ----------- |
-| part | The [Part](../context_variables.md#part) object |
-| category | The [Part Category](../context_variables.md#part-category) which contains the Part |

-| parameters | Map (Python dictionary) object containing the parameters associated with the part instance |
-
-#### Parameter Values
-
-The part parameter *values* can be accessed by parameter name lookup in the template, as follows:
-
-```html
-{% raw %}
-
-Part: {{ part.name }}
-Length: {{ parameters.length }}
-
-{% endraw %}
-```
-
-!!! warning "Spaces"
-    Note that for parameters which include a `space` character in their name, lookup using the "dot" notation won't work! In this case, try using the [key lookup](../helpers.md#key-access) method:
-
-```html
-{% raw %}
-
-Voltage Rating: {% getkey parameters "Voltage Rating" %}
-{% endraw %}
-```
-
-#### Parameter Data
-
-If you require access to the parameter data itself, and not just the "value" of a particular parameter, you can use the `part_parameter` [helper function](../helpers.md#part-parameters).
-
-For example, the following label template can be used to generate a label which contains parameter data in addition to parameter units:
-
-```html
-{% raw %}
-{% extends "label/label_base.html" %}
-
-{% load report %}
-
-{% block content %}
-
-{% part_parameter part "Width" as width %}
-{% part_parameter part "Length" as length %}
-
-<div>
-    Part: {{ part.full_name }}<br>
-    Width: {{ width.data }} [{{ width.units }}]<br>
-    Length: {{ length.data }} [{{ length.units }}]
-</div>
-
-{% endblock content %}
-{% endraw %}
-```
-
-The following label is produced:
-
-{% with id="report-parameters", url="report/label_with_parameters.png", description="Label with parameters" %}

-
-If localization settings on the InvenTree server use a comma (`,`) character as a decimal separator, this may produce an output like:
-
-```html
-{% raw %}
-{% endraw %}
-<head>
-    <style>
-        @page {
-            size: 57,3mm 99,0mm;
-            margin: 0mm;
-        }
-    </style>
-</head>
-```
-
-The resulting `{% raw %}<style>{% endraw %}` CSS block will be *invalid*!
-
-So, if you are writing a template which has custom formatting, (or any other sections which cannot handle comma decimal separators) you must wrap that section in a `{% raw %}{% localize off %}{% endraw %}` block:
-
-```html
-{% raw %}
-{% load l10n %}
-<head>
-    <style>
-        @page {
-            {% localize off %}
-            size: {{ width }}mm {{ height }}mm;
-            {% endlocalize %}
-            margin: 0mm;
-        }
-    </style>
-</head>
-{% endraw %}
-```
-
-!!! tip "Close it out"
-    Don't forget to end with a `{% raw %}{% endlocalize %}{% endraw %}` tag!
-
-!!! tip "l10n"
-    You will need to add `{% raw %}{% load l10n %}{% endraw %}` to the top of your template file to use the `{% raw %}{% localize %}{% endraw %}` tag.
-
-### Extending with Plugins
-
-The [ReportMixin plugin class](../extend/plugins/report.md) allows reporting functionality to be extended with custom features.
-
-## Report Types
-
-InvenTree supports the following reporting functionality:
-
-| Report Type | Description |
-| --- | --- |
-| [Test Report](./test.md) | Format results of a test report against for a particular StockItem |
-| [Build Order Report](./build.md) | Format a build order report |
-| [Purchase Order Report](./purchase_order.md) | Format a purchase order report |
-| [Sales Order Report](./sales_order.md) | Format a sales order report |
-| [Return Order Report](./return_order.md) | Format a return order report |
-| [Stock Location Report](./stock_location.md) | Format a stock location report |
-
-### Default Reports
-
-InvenTree is supplied with a number of default templates "out of the box". These are generally quite simple, but serve as a starting point for building custom reports to suit a specific need.
-
-!!! tip "Read the Source"
-    The source code for the default reports is [available on GitHub](https://github.com/inventree/InvenTree/tree/master/src/backend/InvenTree/report/templates/report). Use this as a guide for generating your own reports!
-
-## Creating Reports
-
-Report templates are created (and edited) via the [admin interface](../settings/admin.md), under the *Report* section. Select the certain type of report template you are wanting to create, and press the *Add* button in the top right corner:
-
-{% with id="report-create", url="report/add_report_template.png", description="Create new report" %}
-{% include 'img.html' %}
-{% endwith %}
-
-!!! tip "Staff Access Only"
-    Only users with staff access can upload or edit report template files.
-
-!!! info "Editing Reports"
-    Existing reports can be edited from the admin interface, in the same location as described above. To change the contents of the template, re-upload a template file, to override the existing template data.
-
-### Name and Description
-
-Each report template requires a name and description, which identify and describe the report template.
-
-### Enabled Status
-
-Boolean field which determines if the specific report template is enabled, and available for use. Reports can be disabled to remove them from the list of available templates, but without deleting them from the database.
-
-### Filename Pattern
-
-The filename pattern used to generate the output `.pdf` file. Defaults to "report.pdf".
-
-The filename pattern allows custom rendering with any context variables which are available to the report. For example, a [test report](./test.md) for a particular [Stock Item](../stock/stock.md#stock-item) can use the part name and serial number of the stock item when generating the report name:
-
-{% with id="report-filename-pattern", url="report/filename_pattern.png", description="Report filename pattern" %}
-{% include 'img.html' %}
-{% endwith %}
-
-
-### Report Filters
-
-Each type of report provides a *filters* field, which can be used to filter which items a report can be generated against. The target of the *filters* field depends on the type of report - refer to the documentation on the specific report type for more information.
-
-For example, the [Test Report](./test.md) filter targets the linked [Stock Item](../stock/status.md) object, and can be used to select which stock items are allowed for the given report. Let's say that a certain test report should only be generated for "trackable" stock items. A filter could easily be constructed to accommodate this, by limiting available items to those where the associated [Part](../part/part.md) is *trackable*:
-
-{% with id="report-filter-valid", url="report/filters_valid.png", description="Report filter  selection" %}
-{% include 'img.html' %}
-{% endwith %}
-
-If you enter an invalid option for the filter field, an error message will be displayed:
-
-{% with id="report-filter-invalid", url="report/filters_invalid.png", description="Invalid filter selection" %}
-{% include 'img.html' %}
-{% endwith %}
-
-!!! warning "Advanced Users"
-    Report filtering is an advanced topic, and requires a little bit of knowledge of the underlying data structure!
-
-### Metadata
-
-A JSON field made available to any [plugins](../extend/plugins.md) - but not used by internal code.
-
-## Report Options
-
-A number of global reporting options are available for customizing InvenTree reports:
-
-{% with id="report-options", url="report/report.png", description="Report Options" %}
-{% include 'img.html' %}
-{% endwith %}
-
-### Enable Reports
-
-By default, the reporting feature is disabled. It must be enabled in the global settings.
-
-
-### Default Page Size
-
-The built-in InvenTree report templates (and any reports which are derived from the built-in templates) use the *Page Size* option to set the page size of the generated reports.
-
-!!! info "Override Page Size"
-    Custom report templates do not have to make use of the *Page Size* option, although it is made available to the template context.
-
-### Debug Mode
-
-As templates are rendered directly to a PDF object, it can be difficult to debug problems when the PDF does not render exactly as expected.
-
-Setting the *Debug Mode* option renders the template as raw HTML instead of PDF, allowing the rendering output to be introspected. This feature allows template designers to understand any issues with the generated HTML (before it is passed to the PDF generation engine).
-
-!!! warning "HTML Rendering Limitations"
-    When rendered in debug mode, @page attributes (such as size, etc) will **not** be observed. Additionally, any asset files stored on the InvenTree server will not be rendered. Debug mode is not intended to produce "good looking" documents!
-
-## Report Assets
-
-User can upload asset files (e.g. images) which can be used when generating reports. For example, you may wish to generate a report with your company logo in the header. Asset files are uploaded via the admin interface.
-
-Asset files can be rendered directly into the template as follows
-
-```html
-{% raw %}
-<!-- Need to include the report template tags at the start of the template file -->
-{% load report %}
-
-<!-- Simple stylesheet -->
-<head>
-  <style>
-    .company-logo {
-      height: 50px;
-    }
-  </style>
-</head>
-
-<body>
-<!-- Report template code here -->
-
-<!-- Render an uploaded asset image -->
-<img src="{% asset 'company_image.png' %}" class="company-logo">
-
-<!-- ... -->
-</body>
-
-{% endraw %}
-```
-
-!!! warning "Asset Naming"
-    If the requested asset name does not match the name of an uploaded asset, the template will continue without loading the image.
-
-!!! info "Assets location"
-    You need to ensure your asset images to the report/assets directory in the [data directory](../start/intro.md#file-storage). Upload new assets via the [admin interface](../settings/admin.md) to ensure they are uploaded to the correct location on the server.
-
-
-## Report Snippets
-
-A powerful feature provided by the django / WeasyPrint templating framework is the ability to include external template files. This allows commonly used template features to be broken out into separate files and re-used across multiple templates.
-
-To support this, InvenTree provides report "snippets" - short (or not so short) template files which cannot be rendered by themselves, but can be called from other templates.
-
-Similar to assets files, snippet template files are uploaded via the admin interface.
-
-Snippets are included in a template as follows:
-
-```
-{% raw %}{% include 'snippets/<snippet_name.html>' %}{% endraw %}
-```
-
-For example, consider a stocktake report for a particular stock location, where we wish to render a table with a row for each item in that location.
-
-```html
-{% raw %}
-
-<table class='stock-table'>
-  <thead>
-    <!-- table header data -->
-  </thead>
-  <tbody>
-    {% for item in location.stock_items %}
-    {% include 'snippets/stock_row.html' with item=item %}
-    {% endfor %}
-  </tbody>
-
-{% endraw %}
-```
-
-!!! info "Snippet Arguments"
-    Note above that named argument variables can be passed through to the snippet!
-
-And the snippet file `stock_row.html` may be written as follows:
-
-```html
-{% raw %}
-<!-- stock_row snippet -->
-<tr>
-  <td>{{ item.part.full_name }}</td>
-  <td>{{ item.quantity }}</td>
-</tr>
-{% endraw %}
-```

+title: InvenTree Templates
+---
+
+## Template Overview
+
+InvenTree supports a customizable reporting ecosystem, allowing the user to develop document templates that meet their particular needs.
+
+PDF files are generated from custom HTML template files which are written by the user.
+
+Templates can be used to generate *reports* or *labels* which can be  used in a variety of situations to format data in a friendly format for printing, distribution, conformance and testing.
+
+In addition to providing the ability for end-users to provide their own reporting templates, some report types offer "built-in" report templates ready for use.
+
+## Template Types
+
+The following types of templates are available:
+
+### Reports
+
+Reports are intended to serve as formal documents, and can be used to generate formatted PDF outputs for a variety of purposes.
+
+Refer to the [report templates](./report.md) documentation for further information.
+
+### Labels
+
+Labels can also be generated using the templating system. Labels are intended to be used for printing small, formatted labels for items, parts, locations, etc.
+
+Refer to the [label templates](./labels.md) documentation for further information.
+
+### Template Model Types
+
+When generating a particular template (to render a report or label output), the template is rendered against a particular "model" type. The model type determines the data that is available to the template, and how it is formatted.
+
+To read more about the model types for which templates can be rendered, and the associated context information, refer to the [context variables](./context_variables.md) documentation.
+
+### Default Reports
+
+InvenTree is supplied with a number of default templates "out of the box" - for generating both labels and reports. These are generally quite simple, but serve as a starting point for building custom reports to suit a specific need.
+
+!!! tip "Read the Source"
+    The source code for the default reports is [available on GitHub](https://github.com/inventree/InvenTree/tree/master/src/backend/InvenTree/report/templates/report). Use this as a guide for generating your own reports!
+
+### Extending with Plugins
+
+The [ReportMixin plugin class](../extend/plugins/report.md) allows reporting functionality to be extended with custom features.
+
+## WeasyPrint Template Rendering
+
+InvenTree report templates utilize the powerful [WeasyPrint](https://weasyprint.org/) PDF generation engine.
+
+To read more about the capabilities of the report templating engine, and how to use it, refer to the [weasyprint documentation](./weasyprint.md).
+
+## Creating Templates
+
+Report and label templates can be created (and edited) via the [admin interface](../settings/admin.md), under the *Report* section.
+
+Select the type of template you are wanting to create (a *Report Template* or *Label Template*) and press the *Add* button in the top right corner:
+
+{% with id="report-list", url="report/report_template_admin.png", description="Report templates in admin interface" %}
+{% include 'img.html' %}
+{% endwith %}
+
+!!! tip "Staff Access Only"
+    Only users with staff access can upload or edit report template files.
+
+!!! info "Editing Reports"
+    Existing reports can be edited from the admin interface, in the same location as described above. To change the contents of the template, re-upload a template file, to override the existing template data.
+
+!!! tip "Template Editor"
+    InvenTree also provides a powerful [template editor](./template_editor.md) which allows for the creation and editing of report templates directly within the browser.
+
+### Name and Description
+
+Each report template requires a name and description, which identify and describe the report template.
+
+### Enabled Status
+
+Boolean field which determines if the specific report template is enabled, and available for use. Reports can be disabled to remove them from the list of available templates, but without deleting them from the database.
+
+### Filename Pattern
+
+The filename pattern used to generate the output `.pdf` file. Defaults to "report.pdf".
+
+The filename pattern allows custom rendering with any context variables which are available to the report. For example, a test report for a particular [Stock Item](../stock/stock.md#stock-item) can use the part name and serial number of the stock item when generating the report name:
+
+{% with id="report-filename-pattern", url="report/filename_pattern.png", description="Report filename pattern" %}
+{% include 'img.html' %}
+{% endwith %}
+
+
+### Template Filters
+
+Each template instance provides a *filters* field, which can be used to filter which items a report or label template can be generated against. The target of the *filters* field depends on the model type associated with the particular template.
+
+As an example, let's say that a certain `StockItem` report should only be generated for "trackable" stock items. A filter could easily be constructed to accommodate this, by limiting available items to those where the associated [Part](../part/part.md) is *trackable*:

+
+{% with id="report-filter-invalid", url="report/filters_invalid.png", description="Invalid filter selection" %}
+{% include 'img.html' %}
+{% endwith %}
+
+!!! warning "Advanced Users"
+    Report filtering is an advanced topic, and requires a little bit of knowledge of the underlying data structure!
+
+### Metadata

+
+## Reporting Options
+
+A number of global reporting options are available for customizing InvenTree reports:
+
+{% with id="report-options", url="report/report.png", description="Report Options" %}
+{% include 'img.html' %}
+{% endwith %}
+
+### Enable Reports
+
+By default, the reporting feature is disabled. It must be enabled in the global settings.
+
+
+### Default Page Size
+
+The built-in InvenTree report templates (and any reports which are derived from the built-in templates) use the *Page Size* option to set the page size of the generated reports.
+
+!!! info "Override Page Size"
+    Custom report templates do not have to make use of the *Page Size* option, although it is made available to the template context.

+
+## Report Assets
+
+User can upload asset files (e.g. images) which can be used when generating reports. For example, you may wish to generate a report with your company logo in the header. Asset files are uploaded via the admin interface.
+
+Asset files can be rendered directly into the template as follows
+
+```html
+{% raw %}
+<!-- Need to include the report template tags at the start of the template file -->
+{% load report %}
+
+<!-- Simple stylesheet -->

+<!-- Render an uploaded asset image -->
+<img src="{% asset 'company_image.png' %}" class="company-logo">
+
+<!-- ... -->
+</body>
+
+{% endraw %}
+```
+
+!!! warning "Asset Naming"
+    If the requested asset name does not match the name of an uploaded asset, the template will continue without loading the image.
+
+!!! info "Assets location"
+    You need to ensure your asset images to the report/assets directory in the [data directory](../start/intro.md#file-storage). Upload new assets via the [admin interface](../settings/admin.md) to ensure they are uploaded to the correct location on the server.

-| Variable | Description |
-| --- | --- |
-| stock_item | The individual [Stock Item](./context_variables.md#stockitem) object for which this test report is being generated |
-| serial | The serial number of the linked Stock Item |
-| part | The [Part](./context_variables.md#part) object of which the stock_item is an instance |
-| parameters | A dict object representing the [parameters](../part/parameter.md) of the referenced part |
-| test_keys | A list of the available 'keys' for the test results recorded against the stock item |
-| test_template_list | A list of the available [test templates](../part/test.md#part-test-templates) for the referenced part |
-| test_template_map | A map / dict of the available test templates |
-| results | A dict of test result objects, where the 'key' for each test result is a shortened version of the test name (see below) |
-| result_list | A list of each test result object |
-| installed_items | A flattened list representing all [Stock Item](./context_variables.md#stockitem) objects which are *installed inside* the referenced [Stock Item](./context_variables.md#stockitem) object |
-
-#### Results
-
-The *results* context variable provides a very convenient method of callout out a particular test result by name.
-
-#### Example
-
-Say for example that a Part "Electronic Widget" has a stock item with serial number #123, and has a test result uploaded called "Firmware Checksum". The templated file can reference this data as follows:
-
-``` html
-<h3>Part: {% raw %}{{ part.name }}{% endraw %}</h3>
-<b>Serial Number: {% raw %}{{ stock_item.serial }}{% endraw %}</b>
-<hr>
-<p>
-Firmware Checksum: {% raw %}{{ results.firmwarechecksum.value }}.
-Uploaded by {{ results.firmwarechecksum.user }}{% endraw %}
-</p>
-```
-
-#### Installed Items
-
-The *installed_items* context variable is a list of all [StockItem](./context_variables.md#stockitem) instances which are installed inside the [StockItem](./context_variables.md#stockitem) referenced by the report template. Each [StockItem](./context_variables.md#stockitem) can be dereferenced as follows:
-
-```html
-{% raw %}
-<table>
-    {% for sub_item in installed_items %}
-    <tr>
-        <td>{{ sub_item.full_name }}</td>
-        <td>Serial Number: {{ sub_item.serial }}</td>
-        <td>Pass: {{ sub_item.passedAllRequiredTests }}</td>
-    </tr>
-    {% endfor %}
-</table>
-{% endraw %}
-```
-
-### Default Report Template
-
-A default *Test Report* template is provided out of the box, which is useful for generating simple test reports. Furthermore, it may be used as a starting point for developing custom test reports:
-
-{% with id="test-report-example", url="report/test_report_example.png", description="Example Test Report" %}
-{% include "img.html" %}
-{% endwith %}
-
-View the [source code](https://github.com/inventree/InvenTree/blob/master/src/backend/InvenTree/report/templates/report/inventree_test_report_base.html) for the default test report template.

+title: Weasyprint Templates
+---
+
+## WeasyPrint Templates
+
+We use the powerful [WeasyPrint](https://weasyprint.org/) PDF generation engine to create custom reports and labels.
+
+!!! info "WeasyPrint"
+    WeasyPrint is an extremely powerful and flexible reporting library. Refer to the [WeasyPrint docs](https://doc.courtbouillon.org/weasyprint/stable/) for further information.
+
+### Stylesheets
+
+Templates are rendered using standard HTML / CSS - if you are familiar with web page layout, you're ready to go!
+
+### Template Language
+
+Uploaded report template files are passed through the [django template rendering framework]({% include "django.html" %}/topics/templates/), and as such accept the same variable template strings as any other django template file. Different variables are passed to the report template (based on the context of the report) and can be used to customize the contents of the generated PDF.
+
+### Context Variables
+
+!!! info "Context Variables"
+  	Templates will have different variables available to them depending on the report type. Read the detailed information on each available report type for further information.
+
+Please refer to the [Context variables](./context_variables.md) page.
+
+
+### Conditional Rendering
+
+The django template system allows for conditional rendering, providing conditional flow statements such as:
+
+```
+{% raw %}
+{% if <condition> %}
+{% do_something %}
+{% elif <other_condition> %}
+<!-- something else -->
+{% else %}
+<!-- finally -->
+{% endif %}
+{% endraw %}
+```
+
+```
+{% raw %}
+{% for <item> in <list> %}
+Item: {{ item }}
+{% endfor %}
+{% endraw %}
+```
+
+!!! info "Conditionals"
+    Refer to the [django template language documentation]({% include "django.html" %}/ref/templates/language/) for more information.
+
+### Localization Issues
+
+Depending on your localization scheme, inputting raw numbers into the formatting section template can cause some unintended issues. Consider the block below which specifies the page size for a rendered template:
+
+```html
+{% raw %}
+<head>
+    <style>
+        @page {
+            size: {{ width }}mm {{ height }}mm;
+            margin: 0mm;
+        }
+    </style>
+</head>
+{% endraw %}
+```
+
+If localization settings on the InvenTree server use a comma (`,`) character as a decimal separator, this may produce an output like:
+
+```html
+{% raw %}
+{% endraw %}
+<head>
+    <style>
+        @page {
+            size: 57,3mm 99,0mm;
+            margin: 0mm;
+        }
+    </style>
+</head>
+```
+
+The resulting `{% raw %}<style>{% endraw %}` CSS block will be *invalid*!
+
+So, if you are writing a template which has custom formatting, (or any other sections which cannot handle comma decimal separators) you must wrap that section in a `{% raw %}{% localize off %}{% endraw %}` block:
+
+```html
+{% raw %}
+{% load l10n %}
+<head>
+    <style>
+        @page {
+            {% localize off %}
+            size: {{ width }}mm {{ height }}mm;
+            {% endlocalize %}
+            margin: 0mm;
+        }
+    </style>
+</head>
+{% endraw %}
+```
+
+!!! tip "Close it out"
+    Don't forget to end with a `{% raw %}{% endlocalize %}{% endraw %}` tag!
+
+!!! tip "l10n"
+    You will need to add `{% raw %}{% load l10n %}{% endraw %}` to the top of your template file to use the `{% raw %}{% localize %}{% endraw %}` tag.
