+This is an online version of [mat2](https://0xacab.org/jvoisin/mat2).
+Keep in mind that this is a beta version, don't rely on it for anything
+serious, yet.
+
+# How to deploy it?
+
+Since mat2 isn't available in debian stable yet, you might want to add this to
+/etc/apt/preferences.d/ to be able to install `mat2` via apt.
+
+```
+Package: *
+Pin: release o=Debian,a=unstable
+Pin-Priority: 10
+```
+
+Then:
+
+```
+# apt install git nginx-light uwsgi uwsgi-plugin-python3 mat2 --no-install-recommends
+# cd /var/www/
+# git clone https://0xacab.org/jvoisin/mat2-web.git
+# mkdir ./mat2-web/uploads/
+# chown -R www-data:www-data ./mat2-web
+# service uwsgi start
+# service nginx start
+```
+
+Since uwsgi isn't fun to configure, feel free to slap this into your
+`/etc/uwsgi/apps-enabled/mat2-web.ini`:
+
+```
+[uwsgi]
+module=main
+chdir = /var/www/mat2-web/
+callable = app
+wsgi-file = main.py
+master = true
+workers = 1
+
+uid = www-data
+gid = www-data
+
+# kill stalled processes
+harakiri = 30
+die-on-term = true
+
+socket = mat2-web.sock
+chmod-socket = 774
+plugins = python3
+```
+
+and this into your `/etc/nginx/site-enabled/mat2-web`:
+
+```
+        location / { try_files $uri @yourapplication; }
+        location @yourapplication {
+                include uwsgi_params;
+                uwsgi_pass unix:/var/www/mat2-web/mat2-web.sock;
+        }
+```
+
+It should now be working.
