 # Storage format:

-#   - Use ~/.config/gitconfigs/ as base
-#   - Repository identifier is determined by the first commit ID
+#   - Use ~/.config/gitconfigs/ as base.
+#   - Repository identifier is determined by it's path in the system.
+#     That's the best choice if you have the same repository checked out
+#     multiple times and with different configurations.
+#   - Repository identifier can also be determined by the first commit ID
 #     (not repo URL or any other volatile information). So this
 #     script may fail if you're doing improbable stuff like rebasing
 #     your repo and removing the initial commit.

 #
-#   - Find all git configurations
-#   - Make a backup at $BASE/$ID/config.$DATE if config differs
