-Barrier is an open-source kvm software.
+[Barrier][4] is an open-source kvm software that allows you to control multiple computers with one
+keyboard and mouse.
 
-- Install on macOS
-{% highlight shell %}
-brew cask install barrier
-{% endhighlight %}
+It mimics the functionality of a [KVM switch][3], which historically would allow you to use a single keyboard and mouse
+to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment.
+Barrier does this in software.
 
----
+## Usage
+Install and run barrier on each machine that will be sharing. On the machine with the keyboard and mouse, make it the server.
