 Reverse proxy
 --------------
 
-In order to make funkwhale accessible from outside your server and to play nicely with other applications on your machine, you should configure a reverse proxy. At the moment, we only have documentation for nginx, if you know how to implement the same thing for apache, you're welcome.

+Apache2
+^^^^^^^
+
+.. note::
+
+    Apache2 support is still very recent and the following features
+    are not working yet:
+
+    - Websocket (used for real-time updates on Instance timeline)
+    - Transcoding of audio files
+
+    Those features are not necessary to use your Funkwhale instance, and
+    transcoding in particular is still in alpha-state anyway.
+
+Ensure you have a recent version of apache2 installed on your server.
+You'll also need the following dependencies::
+
+   apt install libapache2-mod-xsendfile
+
+Then, download our sample virtualhost file:
+
+.. parsed-literal::
+
+    curl -L -o /etc/apache2/sites-available/funkwhale.conf "https://code.eliotberriot.com/funkwhale/funkwhale/raw/|version|/deploy/apache.conf"
+    ln -s /etc/apache2/sites-available/funkwhale.conf /etc/apache2/sites-enabled/
+
+You can tweak the configuration file according to your setup, especially the
+TLS configuration. Otherwise, defaults, should work if you followed the
+installation guide.
+
+Check the configuration is valid with ``apache2ctl configtest``, and once you're
+done, load the new configuration with ``service apache2 restart``.
