 # SSH port forwarding
+Local port forwarding allows ssh to connect one of your ports to the
+destination's port. This is particularly useful for localhosted websites, which
+you can run on the host and access on your machine
+
+Some key terms:
+```
+<client-port> = Port on the machine you're using to ssh. Ex: laptop
+<host-port>   = Port on the machine running sshd
+<host-address> = URL of machine running the sshd, which you're logging onto
+<url-from-host> = Name relative to the host machine who's port the host forwards
+```
+
+The opens an ssh tunnel without obstructing the current terminal:
+```bash
     ssh -p10011 -NL 7000:localhost:8080 emiliko@localhost &
-Opens an ssh tunnel without obstructing the current terminal. Syntax for the
-tunnel looks like:
-    <client_port>:<url_from_host:host_port>
+    ssh -NL <client-port>:<url-from-host>:<host-port> <user>@<host-address> &
+```
+
+# In config file
+The syntax in the config is quite similar
+
+```ssh
+    LocalForward 8001 localhost:7000
+    LocalForward <client-port> <host-address>:<host-port>
+```
