+richdocuments – ownCloud application to integrate Collabora Online
+====================================================================
+
+Installation
+------------
+
+    make dist
+
+Creates a tarball. The contents should go under `owncloud/apps/richdocuments`.
+
+    rpmbuild -ba -vv owncloud-collabora-online.spec
+
+Creates an RPM package (tested only with openSUSE). The [CODE VM](https://collaboraoffice.com/code/) uses it.
+
+Memcache is a requirement (tested only with APCu). Install php-apcu, php5-apcu, or whatever this package is called on your Linux distro, and add the following line to owncloud/config/config.php:
+
+    'memcache.local' => '\OC\Memcache\APCu',
+
+From command line you can use:
+
+    occ config:system:set --value='\OC\Memcache\APCu' memcache.local
+
+You can enable richdocument application from the command line:
+
+    occ app:enable richdocuments
+
+You need to configure the WOPI Client URL, which is where the LibreOffice Online WebSocket Daemon (loolwsd) is listening. It is in Admin - Collabora Online section in ownCloud, or you can set it from command line:
+
+    occ config:app:set --value='https://<hostname or IP address>:<port>' richdocuments wopi_url
+
+Default port is 9980. If loolwsd was compiled without SSL (like in the [CODE VM](https://collaboraoffice.com/code/)), you have to write `http` instead of `https`. If you use SSL, and you get the following error:
+
+    cURL error 60: SSL certificate problem: self signed certificate in certificate chain
+
+You have to add the CA cert manually to ownCloud trusted cert storage:
+
+    cat ca-chain.cert.pem >> owncloud/resources/config/ca-bundle.crt
