Documentation

Access-centered content checklist

Text styling

• The content is written with plain language (where relevant).
• If there are headers, they use the proper header tags (with only one level-one header: H1 or # in markdown).
• All links describe where they link to (for example, check the Nebari website).
• This content adheres to the Nebari style guides.

Non-text content

• All content is represented as text (for example, images need alt text, and videos need captions or descriptive transcripts).
• If there are emojis, there are not more than three in a row.
• Don't use flashing GIFs or videos.
• If the content were to be read as plain text, it still makes sense, and no information is missing.

This is a first pass on the writing, I still need to update the bottom part as I think its confusing

@viniciusdc This covers a lot of really great information! I left a few suggestions on content and also did a grammatical review. Thanks for opening this!

[kcpevey]

The commas in this section throw me off. Given that this is a long list of items and, I think, these things are sequential, could it instead move to a numbered list and the trailing punctuation removed?

[viniciusdc]

yes not a problem, I tried to follow what jupyterhub did https://jupyterhub.readthedocs.io/en/latest/reference/technical-overview.html#how-the-subsystems-interact, though I kept iterating this list and ended up like this, thanks for catching it!

[viniciusdc]

refactored this a bit

[kcpevey]

@viniciusdc is this ready for review again?

[viniciusdc]

I am just refactoring that last part, will ping you shortly

[viniciusdc]

sorry for the delay here @kcpevey, I finished my updates on this, its now ready for a final review. I am happy with how the last sections ended up now :)
