+# `copybuffer` plugin
+
+This plugin binds the ctrl-o keyboard shortcut to a command that copies the text
+that is currently typed in the command line ($BUFFER) to the system clipboard.
+
+This is useful if you type a command - and before you hit enter to execute it - want
+to copy it maybe so you can paste it into a script, gist or whatnot.

+## NG Plugin
+
+This [ng plugin](https://github.com/robbyrussell/oh-my-zsh/tree/master/plugins/ng)
+ adds completion support for Angular's CLI (named ng).
+
+Ng is hosted on [ng home](https://github.com/catull/angular-cli)
+
+It is used to generate Angular 2 app "stubs", build those apps, configure them,
+test them, lint them etc.
+
+Ahem, "stubs" is not what Angular engineers refer to the items ng can generate
+for you.
+
+"Stubs" can be any one of:
+- class
+- component
+- directive
+- enum
+- module
+- pipe
+- route
+- service
+
+At the moment, `ng completion` creates a very rough completion for Zsh and
+Bash.
+
+It is missing most of the options and a few arguments.
+In future, this plugin may be shortened to simply being
+
+```zsh
+eval `ng completion`
+```
+
+There is hope this materialises in the 21st century.
