 Or install it yourself as:
 
     $ gem install fog-brightbox
 
+## Configuration
+
+This code can use `fog`'s credentials or can be configured by passing in the
+details to the [Fog::Brightbox::Config](lib/fog/brightbox/config.rb).
+
+### Using `fog`
+
+Assuming credentials are setup as expected by fog, the configuration can be used
+as such:
+
+```ruby
+@config = Fog::Brightbox::Config.new(Fog.credentials)
+```
+
+### Using options Hash
+
+Alternatively credentials can be set using a Hash of options:
+
+```ruby
+@config = Fog::Brightbox::Config.new(
+    brightbox_client_id: "cli-12345",
+    brightbox_secret: "<demo-value>"
+)
+```
+
+See [Fog::Brightbox::Config's documentation](lib/fog/brightbox/config.rb) for
+all possible settings.
+
 ## Usage
 
+Here is a basic example of usage:
+
+```ruby
+require "fog/brightbox"
+
+# Passing either a configuration object or Hash of options are supported
+@service = Fog::Brightbox::Compute.new(
+  brightbox_client_id: "acc-12345",
+  brightbox_secret: "<demo-value>"
+)
+
+# Request all servers using the class method
+servers = @service.servers.all
+servers.each do |server|
+  puts server.id
+end
+```
+
+An alternative using a configuration object instead:
+
+```ruby
+require "fog/brightbox"
+
+@config = Fog::Brightbox::Config.new(
+  brightbox_client_id: "acc-12345",
+  brightbox_secret: "<demo-value>"
+)
+@service = Fog::Brightbox::Compute.new(@config)
+# Use service as normal
+```
+
+The main advantages of using a configuration option is that it can be set from
+the main `Fog.credentials` which could be configured for  numerous service
+providers.
+
+`Fog::Brightbox::Config` also wraps around credentials itself so will manage
+OAuth access and refresh tokens. This can be disabled with the
+`brightbox_token_management: false` setting.
