 - [Recipes](#recipes) add concise, discoverable, and easy-to-follow instructions for common Gatsby tasks. They are smaller units than tutorials.
 - [Tutorials](#tutorials) should provide step-by-step guidance for Gatsby workflows, listing all pre-requisites and not assuming knowledge or skipping steps.
 
+When writing (or reviewing) learning materials that show Gatsby users how to complete tasks, you are expected to **test out any code examples or steps to ensure they work**. This can also help with writing in your own words, rather than copying from other sources. If you have a demo project or code example that strengthens docs and you don't know where to put it, mention it to the Gatsby Learning team in a PR.

 ### Why use templates?
 
 Here are templates (models) to follow when contributing to Gatsby docs to ensure that the docs accomplish their purpose. If you have a good reason to deviate from the following template structures, mention those reasons in the PR so others can give proper feedback.

 If you're finding a recipe is becoming too long to fit on the Docs Recipes page due to including many prerequisites or steps, consider writing a tutorial instead.

 ### Recipe categories
 
 Grouping recipes by topic will allow users to navigate and learn by subject matter. As recipes following the new format are introduced, you might find a section needs an h2 heading added for the group. The older-style recipes should be gradually replaced with actionable recipes following the template below.

+#### Overview link
+
+To make sure your recipe is linked from the overview page, you must add it to the appropriate category in [`recipes.md`](https://github.com/gatsbyjs/gatsby/blob/master/docs/docs/recipes.md). Otherwise, it will be difficult for Gatsby users to find it, which isn't good for anyone!

 #### Title and description
 
 To help motivate the purpose of a recipe, its title should clearly indicate the task being covered; not just the tool or API being used. E.g. "Using the StaticQuery Component" is more descriptive than "StaticQuery".
