-cd to this repo's directory and install pip dependencies with:

+sudo apt install pipenv
+```
+or
+```bash
+sudo dnf install pipenv
+```
 
-```pipenv install```
+Once installed, you can have pipenv install all python requirements like so:

 ## Command Line Arguments
 
-TODO
+### ***--name*** (Specify one or more mapping names)
 
+You can specify desired mapping names by adding the ***--name*** argument, as many times as you wish:
+
+```bash
+$ pipenv run python3 main.py --name Leg --name Arm
+```
+
+### ***--config*** (Specify an input config file)
+
+You can specify a yaml configuration file to load with this argument, like so:
+
+```bash
+$ pipenv run python3 main.py --config /path/to/config.yaml
+```
+
+So far the config file is only good for storing desired names to be mapped. Here's an example:
+
+```yaml
+
+names:
+    - Manny
+    - Moe
+    - Jack
+
+```
