 Remove some versions:
 
-    $ n rm 0.2.4 v0.3.0
+    $ n rm 0.9.4 v0.10.0
 
 Instead of using `rm` we can simply use `-`:
 
-    $ n - 0.2.4
+    $ n - 0.9.4
 
 ### Binary Usage
 
 When running multiple versions of node, we can target
 them directly by asking `n` for the binary path:
 
-    $ n bin 0.3.3
-    /usr/local/n/versions/0.3.3/bin/node
+    $ n bin 0.9.4
+    /usr/local/n/versions/0.9.4/bin/node
 
 Or by using a specific version through `n`'s `use` sub-command:
 
-    $ n use 0.3.3 some.js
+    $ n use 0.9.4 some.js
 
 with flags:
 
-    $ n as 0.3.3 --debug some.js
+    $ n as 0.9.4 --debug some.js
 
 ## Usage
