 Ruby-LXC is a Ruby binding for liblxc. It allows the creation and management
 of Linux Containers from Ruby scripts.
 
+
 ## Build and installation
 
-Clone this repository and run the commands below.
+Currently the binding is developed and tested against liblxc 1.0.0 build. To build ruby-lxc you need
+- ubuntu 14.04
+- lxc ipackage
+```sh
+sudo apt-get install lxc liblxc0 lxc-dev
+```
 
-    $ rake native gem
-    # gem install pkg/ruby-lxc-0.1.0.gem
+- Build essential for compiling the bindings
+```sh
+sudo apt-get install build-essential
+```
+
+- Clone this repository and run the commands below (assuming you have bundler).
+```sh
+bundle install
+bundle exec rake compile
+gem install pkg/ruby-lxc-0.1.0.gem
+```
+or just add this to your ```Gemfile```
+```ruby
+gem "ruby-lxc", github: "andrenth/ruby-lxc"
+```
 
 ## Usage
 
-TODO :) For now see the tests in the `test` directory to see how the API
-works.
+- Container lifecycle management (create, start, stop and destroy containers)
+```ruby
+c = LXC::Container.new('foo')
+c.create('ubuntu') # create a container named foo with ubuntu template
+c.start
+c.stop
+c.destroy
+```
+
+- Additional state changing operations (freezing, unfreezing and cloning containers)
+```ruby
+c.freeze
+c.unfreeze
+c.reboot
+c.shutdown
+```
+
+- Clone a container
+```ruby
+c.clone('bar') # clone foo into bar. parent container has to bee in freeze or stopped state.
+```
+
+- Wait for a state change
+```ruby
+c.wait('STOPPED', 10) # wait till container goes to STOPPED state, else timeout after 10 seconds
+```
