 # taft — Totally Adequate File Transfer
 
 A simple wrapper around nc(1) and tar(1).
+taft's main focus is speed, so no encryption is involved, to minimize overhead.
+If you're looking for a *secure* way to transfer files, go with sftp(1) instead.
 
 *Named after William Howard Taft, [America's greatest president by volume](https://idlewords.com/talks/website_obesity.htm)*.
+
+## Usage
+
+Destination host:
+
+```
+$ mkdir destination; cd destination
+$ taft receive
+```
+
+Source host:
+
+```
+$ mkdir source; cd source
+$ touch a b c
+$ taft send 192.168.178.42 # destination IP address
+./
+./c
+./b
+./a
+```
+
+The default port is 1337.
+It can be changed via the `-p` or `--port` option.
