📚 Building server with docs fails

I was following the building documentation available here : https://docs.ludus.cloud/docs/developers/building-from-source#building-with-embedded-documentation

• First step I took all the script block to past it in the terminal to launch the build and got this errors:

Command 'yarn' not found, but can be installed with:
apt install cmdtest
Command 'yarn' not found, but can be installed with:
apt install cmdtest
mv: cannot stat './build': No such file or directory
Command 'go' not found, but can be installed with:
snap install go         # version 1.23.5, or
apt  install golang-go  # version 2:1.21~2
apt  install gccgo-go   # version 2:1.21~2
See 'snap info go' for additional versions.

This could be added to the documentation to get more clear about the steps :

# for debian
apt install golang-go snap

---

For the yarn part it was a little bit harder : I first installed it with apt but had to remove it because I got this message :
