+#### Adding beta documentation
+When documentation is in a beta state, it requires a new, distinct collection of docs. The process is a little nuanced, so make sure to build the documentation locally to make sure it appears how you expect. To create a new collection:
+1. Add content
+* Add a new folder to docs with an underscore (ex: `_steps`).
+* Add documentation sections to that folder, with similar front matter to the `_advanced` and `_basic` sections.
+* Add an overview section that explains the beta state of the category. This should always be `order: 1` in the front matter.
+
+2. Configure layout
+* Update `docs`>`_config.yml` with the new collection you created under `collections` (the same as the folder name - ex: `steps`). While you're there, add the sidebar title under `t`.
+* In `docs`>`_layouts`>`default.html` make a copy of the `basic` or `advanced` section, and modify the div ID and content to correspond to your beta collection. This step requires you to use variables from `_config.yml`.
+* Now in `docs`>`_includes`>`sidebar.html`, create a new section after the basic and advanced sections. Again, copy the `basic` or `advanced` section to use as a template. Be careful with the variable naming—it's a little more complex than in `default.html`, and requires you to use variables from `_config.yml`.
