##Run Tetra on Your Personal Computer

1. Create a directory (i.e. Tetra).
2. Place tetra.py in the directory.
3. Place Yale's Bright Star Catalog in the directory: BSC5
4. Create a subdirectory called 'pics'
5. Place images in 'pics' such as this one: Aurora
6. Run 'python tetra.py'

The first run may take a while as it needs to generate the catalog. From then on, the majority of the runtime will be taken up by loading the catalog into memory and image processing.
