+## Run the server outside Docker
+
+Run the app:
+
+```commandline
+sh <(curl https://pkgx.sh) +python.org +virtualenv.pypa.io sh
+
+source venv/bin/activate
+
+python app.py
+
+# See Troubleshooting below if that doesn't work out of the box.
+```
+
+
+
+Run a test:
+
+```commandline
+python webpush.py
+```
+
+
+
+Run haproxy (on a Mac):
+
+* Create "haproxy-config" directory for those files above, eg. /usr/local/etc/haproxy
+
+* Comment out the `log rsyslog` and `bind *:443` lines in /usr/local/etc/haproxy/haproxy.cfg and then run:
+
+`haproxy -f /usr/local/etc/haproxy/haproxy.cfg`
+
+

+  SQLALCHEMY_DATABASE_URI and add `sqlite:////...` with the full path to the data/webpush.db file.
+  (Why does the relative path of `sqlite:///...` not work for a relative path?)
