+### Configure ssh SOCKS proxy
+
 If you have access to some ssh server, say `socksserver`, you can set up ssh SOCKS tunnel.
 First, modify and add the following to `.ssh/config`:
+
 ```ssh
 Host socksserver-td
 Hostname 123.456.789.012
 User cookiemonster
 ProxyCommand nc -X connect -x 127.0.0.1:10500 %h %p
 ```
+
 then run `ssh -D1234 socksserver-td -4`
 
 Now in Firefox you could just go to Preferences->Advanced->Network->Settings and set SOCKSv5 host to localhost:1234.
