+# Installing Dependencies for Python
+
+Converting the code to Python 3 currently requires the packages specified in `requirements.txt`.
+
+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.
+
+# Quick Installation
+
+## Ubuntu 24.04
+
+    sudo apt install python3-git opengnsys-libarchive-c python3-termcolor bsdextrautils
+
+## Add SSH Keys to oglive
+
+The Git system accesses the ogrepository via SSH. To work, it needs the oglive to have an SSH key, and the ogrepository must accept it.
+
+The Git installer can make the required changes with:
+
+    ./opengnsys_git_installer.py --set-ssh-key
+
+Or to do it for a specific oglive:
+
+    ./opengnsys_git_installer.py --set-ssh-key --oglive 1 # oglive number
+
+Running this command automatically adds the SSH key to Forgejo.
+
+The existing key can be extracted with:
+
+    ./opengnsys_git_installer.py --extract-ssh-key --quiet
+
+# Running the Installer
+
+    # ./opengnsys_git_installer.py
+
+It must be run as `root`.
+
+The installer downloads and installs Forgejo, a web interface for Git. The configuration is automatically generated.
+
+Forgejo manages the repositories and SSH access, so it must always be running. By default, it is installed on port 3000.
+
+The default user is `oggit` with the password `opengnsys`.
+
+# Packages with Dependencies
+
+The OgGit system requires Python modules that are not included in Ubuntu 24.04 or have outdated versions.
+
+The package sources can be found in oggit/packages.
+
+# Source Code Documentation
+
+Python documentation can be generated using a utility like pdoc3 (there are multiple possible alternatives):
+
+    # Install pdoc3
+    pip install --user pdoc3
+
+    # Generate documentation
+    pdoc3 --force --html opengnsys_git_installer.py
