The documentation is a wonderful thing - particularly the tabs Features, Useage , FAQ and the Installation guide. Someone has spent a lot of time thinking about what we need to understand and then written it up in a fine style that deserves far more credit. Thank you.
Of course, I love the way sandboxed play services and profiles can be combined to control Android and Google; but it was whilst reading the documentation that I realised I didn't need to search further and that GrapheneOS would be my home ... and donate too.
Is there any other OS documentation on the internet that is as helpful?* The style and accessible detail might even be unique across the mobile/desktop OS spectrum. Reading grapheneos.org, you know that there is no point doing more searches (other than this forum perhaps ;) because it has the canonical answers you are looking for.
(*) The TLP documentation, for optimising linux laptop battery life, at linrunner.de/tlp/index.html might be comparable.
