-This is our spec/working area for a simple command line client for etcd. This client will be bundled with CoreOS. This is all brainstorming at the moment. Please contribute!
+`etcdctl` is a command line client for [etcd][etcd]. It can be used in scripts or for administrators to explore an etcd cluster.
 
-## Example usage
+[etcd]: https://github.com/coreos/etcd
 
-Setting a key on `/foo/bar`: 
+## Getting etcdctl
+
+The latest release is available as a binary at [Github][github-release] along with etcd.
+
+[github-release]: https://github.com/coreos/etcd/releases/
+
+You can also build etcdctl from source:
+
+```
+./build
+```
+
+## Usage
+
+### Key/Value
+
+Setting a key on `/foo/bar`:
+
+```
+etcdctl set /foo/bar "Hello world"
+Hello world
+```
 
-    $ etcdctl set /foo/bar "Hello world"
-    Hello world
-    
 Getting a key:
 
-    $ etcdctl get /foo/bar
-    Hello world
+```
+etcdctl get /foo/bar
+Hello world
+```
 
 Deleting a key:
 
-	  $ etcdctl delete /foo/bar
-    Hello world
+```
+etcdctl delete /foo/bar
+Hello world
+```
 
 Tailing a key:
 
-    $ etcdctl watch /foo/bar -f
-    Hello world
-    .... client hangs forever until ctrl+C printing values as key change
+```
+etcdctl watch /foo/bar -f
+Hello world
+.... client hangs forever until ctrl+C printing values as key change
