-# Installing Dependencies for Python
+# Git component installer
 
-Converting the code to Python 3 currently requires the packages specified in `requirements.txt`.
+This directory contains the installer for the git component for OpenGnsys.
 
-To install Python dependencies, the `venv` module (https://docs.python.org/3/library/venv.html) is used, which installs all dependencies in an isolated environment separate from the system.
+It downloads, installs and configures Forgejo, creates the default repositories and configures SSH keys.
