+liblarch may be harder to come by until distributions package the python3 version of it, alongside GTG 0.6+ itself.
 You can get it meanwhile via PIP (commonly provided by `python3-pip` package):
 
 ```sh
 pip3 install --user -e git+https://github.com/getting-things-gnome/liblarch.git#egg=liblarch
 ```
 
+Alternatively, if you had checked out a specific version of liblarch that you want to test, in a parent folder for example (`../liblarch`), you could do: `pip3 install --user ../liblarch/` (you can later remove that with `pip3 uninstall liblarch` if you need to).
