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.

It looks great! And many thanks for adding these details to the documentation 🚀
My main point of feedback is the distinction between Nebari SSH and JupyterHub SSH, as they serve different purposes. Since Nebari consists of several services, some might interpret SSH-ing into Nebari as directly connecting to the cluster (nodes or pods), which is a distinction worth clarifying from what jupyterhub-ssh does

That is an excellent point, and I didn't appreciate the difference until you pointed it out. Thanks!
