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.

Hello @viniciusdc,

The docs looks great to me, clear and concise. I like the tip on creating a new node group with the desired launch template and migrating workloads to avoid issues with modifying/destroying a node group.

The Test Website check should pass now if you sync/update your branch with upstream.
