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.

Thanks for contributing docs!

Couple of things - you'll need to add this to docs sidebar in order for it show up - here: https://github.com/nebari-dev/nebari-docs/blob/main/docs/sidebars.js#L79

And we keep images in a separate static folder for each diataxis area. Your image should go here: https://github.com/nebari-dev/nebari-docs/tree/main/docs/static/img/how-tos

@kcpevey could you do another pass in here, just to make sure I haven't overlooked anything.
