 ## Dependencies
-
 - GitPython
 - Python (>=3.10)
 
-## Usage
-This script assumes that an enviromental variable has been set which points to the root of the 4DSSE project. This is used to retreive the git log so that author information and last update date information may be read. By default this uses the enviromental variable `_4DSSE_ROOT`; however, this may be changed with the `--root` command line flag. Whatever is set as `--root` will be the name of the enviromental variable this script will search for.
+## Installation
+Generally one is intended to use this by copying `post-commit` into the `.git/hooks` directory. This can be done simply by running the install script (note that the `_4DSEE_ROOT` enviromental variable **must** be set.)
+
+```bash
+install.sh
+```
+
+## Manual Usage
+The python script `formatHeader.py` assumes that an enviromental variable has been set which points to the root of the 4DSSE project. This is used to retreive the git log so that author information and last update date information may be read. By default this uses the enviromental variable `_4DSSE_ROOT`; however, this may be changed with the `--root` command line flag. Whatever is set as `--root` will be the name of the enviromental variable this script will search for.
