+# Pizzatool
+```
+# create virtualenv
+virtualenv-3 venv
+# activate virtualenv
+. venv/bin/activate
+# install pizzatool
+pip install .
+# run pizzatool with frontend in frontend/<myfrontend>/dist
+pizzatool frontend/<myfrontend>/dist
+```
+
+# Frontend Showdown
+For the showdown create your frontend somewhere in `frontend/<myfrontend>`.
+Running `pizzatool frontend/<myfrontend>/dist` will serve
+`frontend/<myfrontend>/dist` at `http://localhost:8000/` and the REST API at
+`http://localhost:8000/api`. You can inspect and test the API in
+`http://localhost:8000/api/docs`.
+Happy Hacking!
