+# right now, we're in /repo/.git/hooks, so let's get that path
+CURRENT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
+
+# let's calculate the parent directory, which is: /repo/.git
+PARENT_DIR="$(dirname "$CURRENT_DIR")"
+
+# calculate grandparent directory (which is what we want): /repo/
+REPO_ROOT="$(dirname "$PARENT_DIR")"
+
+# this is the reason we need to obtain the path
+# to the "repo" directory: because "git diff" has to be executed on it, it won't work otherwise.
