+# Envyable
+
+The simplest yaml to ENV config loader.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'envyable'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install envyable
+
+## Usage
+
+### Rails
+
+Once installed in a Rails app, add a `config/env.yml` file with your config
+separated into environments, like so:
+
+```
+development:
+  API_CLIENT_ID: development-id
+test:
+  API_CLIENT_ID: test-id
+```
+
+The gem will load the correct environment on initialization of the application.
+
+Do not check in the `config/env.yml` file as it may contain application secrets
+that you do not want shared.
+
+### Other applications
+
+You can simply call `Envyable.load(path, environment)` and the yaml file will be loaded into ENV.
+
