+Installation: FreeBSD
+=====================
+
+1. install uwsgi (dependency, but really small): `pkg install uwsgi`
+
+2. add to `/etc/rc.conf`:
+   ```
+   uwsgi_enable="YES"
+   uwsgi_emperor="YES"
+   uwsgi_vassals_dir="/usr/local/www/*/uwsgi.ini"
+   ```
+
+3. start uwsgi `service uwsgi start`
+
+4. Git clone this directory under /usr/local/www/
+
+
+WIP
+===
+
+This is work in progress. Do not expect wonders or good documentation in this
+early stage of development.
