 # analysis-scripts
-A framework for analyzing GFDL model output
+A framework for analyzing GFDL model output.
 
 ### Motivation
 The goal of this project is to provide a simple API to guide the development of
 scripts that produce figures and tables from GFDL model output.  This work will be used
 by a simple web application to provide users an easy interface to interact with model
 output data.
 
-### Requirements
-No external packages are required.
+### How to install this package
+For now I'd recommend creating a virtual enviroment, and then installing the package inside
+of it.
 
-### How to use this framework.
+```bash
+$ python3 -m venv env
+$ source env/bin/activate
+$ pip install --upgrade pip
+$ pip install .
+```
+
+### How to use this framework
 Custom analysis scripts classes can be created that inherit the `AnalysisScript` base
 class, then override its contructor, `requires`, and `run_analysis` methods. For example:
