apertium-init.py instructions more clear

Is it possible to make the instructions of apertium-init.py more clear? Because it's not immediately obvious (to beginners like me) that you need to create your own repo when bootstrapping a new language pair and push to it.
Also could it be added to the wiki that when compiling the language pair you need to enter the apertium-XXX-YYY directory first? Otherwise you get the error that auto-gen.sh doesn't exist...

Review the instructions in apertium-init.py and the repository wiki, focusing on bootstrapping a new language pair and compiling from the apertium-XXX-YYY directory. Done means the instructions explicitly cover creating and pushing a new repository and entering the language-pair directory before running the build steps.
