+* `www.opennet.ru` > `/opennet/www`
+* `bsd.opennet.ru` > `/opennet/bsd`
+* `cisco.opennet.ru` > `/opennet/cisco`
+* `grab.opennet.ru` > `/opennet/grab`

+## Installation
+
+1. Download `nginx/opennet` to `/etc/nginx` folder
+2. Copy `nginx/opennet/server.conf` to `sites-available/opennet.conf`
+3. Alternatively, include `nginx/opennet/locations.conf` to existing website config at `sites-available` then reload nginx configuration
+
+## Issues
+
+1. At this moment, config drops all JS some tabs could not work
+2. Youtube embedded content still works
+3. Redirect cases not implemented yet and require additional rules implementation
