+# Polygraph - polycule visualization for nerds
+
+This program is a thin shell on top of pygraphviz aimed at making it easy to draw a graph of your polyamorous network.
+
+It can, of course, be trivially used for anyone who wants a quick way to define a graph and render it; it's just
+a thin shell on top of a few of pygraphviz' features. Feel free to use it for anything that seems useful to you!
+
+## Installation
+
+On Ubuntu, just run:
+
+```
+sudo apt install graphviz-dev python3-pydot
+pip3 install -r requirements.txt
+```
+
+Now you can define a graph file and run the tool with:
+
+```
+./polygraph.py -i <input_file.json> -o <output_file.json>
+```
+
+See `./polygraph.py --help` for more detailed options.
