+This set of scripts are helpers that modify and create the source packages coming
 from the Ubuntu upstream which need it. It might be because they contain
 non-free stuff, references to Ubuntu that need to be changed, or because we
 want the package to work our way.

+## Steps
+
+Those are the steps done by the helpers:
+
+1. Create local apt configuration, so you don't need to be root to run the helpers
+2. Get the ubuntu and trisquel gpg keys
+3. Get the source packages from their original repo
+4. Uncompress them
+5. Apply the changes described in the helper
+6. Re-package it, adding "triquel$VERSION" version string
 
 ## Recommendations
 
+* You don't need to use sudo in order to run those scripts, but some extra packages are needed:

 * Take care to use the right sourcePackageName, many source packages produce
 several binary packages. `apt-cache showsrc binary-package` can help you.
