+# Templates
+
+Creating templates is a straightforward process, even for those unfamiliar
+with [Go Template](https://pkg.go.dev/text/template). Here are a few things to keep in mind:
+
+- The template should be a single page, without additional `css` or `js` files. However, you can load them from a
+  CDN or other GitHub repositories using [jsdelivr.com](https://www.jsdelivr.com/)
+- Be sure to include the `<meta name="robots" content="nofollow,noarchive,noindex">` tag in the header
+- You can use special "placeholders" (wrapped in `{{` and `}}`) for the rendering error code, message, and other
+  details
+
+Built-in "placeholders" and functions with their examples can be found in the following files:
+
+- [props.go](../internal/template/props.go)
+- [template.go](../internal/template/template.go)
