Coming from personal inconvenience - I've tried to build this from source, and was faced with Microsoft accounts not working. Upon re-reading the READMEs, I didn't find a reason for it, so I resorted to messaging in the Discord, which, after some back and forth, allowed me to understand that additional private stuff is needed for it to work. The question could've been avoided entirely, in my opinion, if this was included in BUILD.md - the place where anyone intending to build from source will come for guidance.
(Not) Secrets should've been linked clearly because it's a crucial piece of info for someone building from source, since normally. I'd expect the source code to fully reflect the pre-built binaries.
The Oracle JDK 8 is now offered at a commercial license and requires an account to download. OpenJDK has no such license and is completely free to use.
the `git clone` command provided doesn't work and gives this error on Debian
```
$ git clone --recursive git@github.com:MultiMC/MultiMC5.git src

Are you sure you want to continue connecting (yes/no)? yes

I am suggesting an alternative command to provide to users in BUILD.md instead.
