Pinot documentation is powered by Gitbook, and a bi-directional Github integration is set up to back up all the changes.
For Pinot Contributor, there are majorly two ways to update the documentations.
This follows the old fashion of updating documentations.
Once the PR got merged, the changes will automatically applied to corresponding Gitbook pages.
Once granted edit permission, contributors could edit any page on Gitbook and then save and merge the changes by themselves. This is one example commit on Github repo to reflect the updates coming from Git book: Adding Update Document Page Commit.
Usually we grant edit permission to committers and active contributors.
