Ideally, the project should not require any documentation to read.
Yep, I know, I think everyone should read to learn, but I've seen so many times peoples' spark die once I tell them "I will send you the docs with clear instructions. If you have any questions, let me know :)". The reply is often " Oh, but it should tell me where to click".
Or maybe it's because the docs are too difficult, I don't know.
Bitwarden is a very convenient password manager for an average computer user. It's very straightforward and easy to use.
I can see some bias here of the people who say "o, just use KeePass and sync the database over some cloud provider". What if there are conflicts? How do they deal with them? I can figure it our but most people I know, won't.
Even the password manager concept is a complicated concept to grasp for many people (that I know). And I can recommend them Bitwarden because it's relatively easy, but KeePass with sync? Maybe, if I commit to actively help them with it.
P.S. I've convinced several people to try out Linux, and they are willing to learn it, but even if they just need to use a browser, they struggle sometimes. I can't imagine them syncing the KeePass database.
