-# TODO: Write docs
+# Templates
+
+Creating templates is a very simple operation, even for those who know nothing at all about [Go Template](https://pkg.go.dev/text/template). All you should know is:
+
+- The template should be one page. Without additional `css` or `js` files (but you can load them from the CDN or another GitHub repositories using [jsdelivr.com](https://www.jsdelivr.com/), for example)
+- Don't forget to include `<meta name="robots" content="noindex, nofollow" />` tag in the header
+- You can use a special "placeholders" (wrapped in `{{` and `}}`) for the rendering error code, message and others (see details below)
