+## Development
+
+To contribute and develop on the bench CLI tool, clone this repo and create an editable install. In editable mode, you may get the following warning everytime you run a bench command:
+
+	WARN: bench is installed in editable mode!
+
+	This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`
+
+
+```sh
+$ git clone https://github.com/frappe/bench ~/bench-repo
+$ pip3 install -e ~/bench-repo
+$ bench src
+/Users/frappe/bench-repo
+```
+
+To clear up the editable install and switch to a stable version of bench, uninstall via pip and delete the corresponding egg file from the python path.
+
+
+```sh
+# Delete bench installed in editable install
+$ rm -r $(find ~ -name '*.egg-info')
+$ pip3 uninstall frappe-bench
+
+# Install latest released version of bench
+$ pip3 install -U frappe-bench
+```
+
+To confirm the switch, check the output of `bench src`. It should change from something like `$HOME/bench-repo` to `/usr/local/lib/python3.6/dist-packages` and stop the editable install warnings from getting triggered at every command.

This sets up a complete bench folder with an `apps` folder which contains all the Frappe apps available in the current bench, `sites` folder that stores all site data seperated by individual site folders, `config` folder that contains your redis, NGINX and supervisor configuration files. The `env` folder consists of all python dependencies the current bench and installed Frappe applications have.
  - **restart**: Restart web, supervisor, systemd processes units. Used in production setup.
- - **update**: Updates bench tool and if executed in a bench directory, without any flags will backup, pull, setup requirements, build, run patches and restart bench. Using specific flags will only do certain tasks instead of all.
