+How To Add Localized Screenshots
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+All images are stored in the top-level 'images' folder. Original
+screenshots in English are in the 'C' subfolder. Localized screenshots
+are in 'LANG' folders, where LANG is your two/four-letter language code.
+
+It's important to preserve both paths and names when saving localized
+versions of the screenshots. Otherwise documentation won't build properly,
+if at all.
+
+How To Submit Translation
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are multiple ways to submit your translation depending on the access
+level you have for the Git repository. 
+
+If you cloned the Git repository anonymously, and you intend to either send
+the files to your GNOME i18n team or submit a patch to the bug tracker, do
+this:
+
+1. Add all the files you created ('git add') and commit them ('git commit').
+
+2. Run 'git pull --rebase' to sync your local copy to the main remote Git
+repository.
+
+3. Run 'git format-patch origin/master' to generate Git-formatted patch 
+(or patches).
+
+4. Submit newly create files.
+
+If you cloned the Git repository via SSH, it means you already have the
+access to push directly to the remote repository. Simply run add and commit
+all your changes, then run 'git push origin master'.
