+I got tired of APRS-IS websites not showing me all the paths that packets
+take, only the shortest path to IS. So this is a Python 3 tool that turns
+direwolf logs into a REST API in JSON format.
+
+## Setup
+1. Run direwolf with logging to CSV on by using `-l`. (`-L` not yet implemented).
+1. Install requirements using `pip install -r requirements.txt`.
+2. Run `app.py` with either a Python call or gunicorn (or some other WSGI server).
+You can use screen to detach the session.
+    - Default URL is http://127.0.0.1:5000
+3. Access the API from whatever other system you want.
+
+
+
+## Endpoints:
+-`/packets` - gives the most recent packets, with the fields from the Dire Wolf
+User Guide.
+
+Example of an object packet sent by W1CDN-1 and digipeated by K0UND-2:
+```
