 ### Shell-completion
 
-Shell completions are in `shell-completions`.
+Shell completions are in [scripts/shell-completions](./scripts/shell-completions) directory of this repository.
 
 For bash: install `shell-completions/bash`
 as e.g. `/etc/bash_completion.d/ghcup` (depending on distro)
 and make sure your bashrc sources the startup script
 (`/usr/share/bash-completion/bash_completion` on some distros).
 
-### Cross support
+### Compiling from source
+
+Compiling from source is supported for both source tarballs and arbitrary git refs. See `ghcup compile ghc --help`
+for a list of all available options.
+
+If you need to overwrite the existing `build.mk`, check the default files
+in [data/build_mk](./data/build_mk), copy them somewhere, adjust them and
+pass `--config path/to/build.mk` to `ghcup compile ghc`.
+Common `build.mk` options are explained [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/using#build-configuration).
+
+Make sure your system meets all the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation).

+#### Cross support
 
 ghcup can compile and install a cross GHC for any target. However, this
 requires that the build host has a complete cross toolchain and various
