+Command Completion
+==================
+
+Shell command completion is provided by the script at 
+`/misc/completion/ipfs-completion.bash`.
+
+The simplest way to see it working is to run 
+`source misc/completion/ipfs-completion.bash` straight from your shell. This
+is only temporary and to fully enable it, you'll have to follow one of the steps
+below.
+
+Linux
+-----
+### Bash
+
+For bash, completion can be enabled in a couple of ways. One is to add the line
+`source $GOPATH/src/github.com/ipfs/go-ipfs/misc/completion/ipfs-completion.bash` 
+into your `~/.bash_completion`. It will automatically be loaded the next time 
+bash is loaded.
+To enable ipfs command completion globally on your system you may also 
+copy the completion script to `/etc/bash_completion.d/`.
