Working on a doc piece

Within the markdown files for each of the doc pieces above, you may find in comment blocks some suggested outlines and reference materials:

• Where to look in our code regarding the topic
• Our v1 doc on the corresponding feature
• Doc pieces from external projects on similar topics

As you work on the docs, use existing and external materials critically as examples or inspirations. You are more than welcome to explain things in your own style.

Also, feel free to ask us if you have any questions. You may tag us directly in your PR.

Adopting a doc piece

• Create a PR and reference this issue
• Within your PR, mark clearly which piece(s) you are working on
• Once we see your PR, we'll mark in this issue that the corresponding piece is under work in progress by you
• If you don't feel like continue working on the piece, close the PR so that other people can pick it up

Note that:

• Your initial work does not have to include all the content for the piece, put WIP to indicate that you are working on it
• You don't need to ask for permission or progression, etc. As long as there is no open PR (we will mark it beside the section), you can pull one up for the piece you are working on

Have you read the Contributing Guidelines on issues?

Yes
