+
+`lita_dotenv` is designed to allow storing an entire [Lita bot](https://www.lita.io/)config in an `.env` file.
+
+## Installation
+
+Add `lita_dotenv` to your Lita instance's Gemfile:
+
+``` ruby
+gem "lita_dotenv"
+```
+
+## Configuration
+
+### .env
+
+`DotenvConfig` uses a simple parser that follows the following rules for assigning ENV variable names to Lita paths:
+
+1. all paths begin with `LITA_`
+2. all paths are designed to match Lita configure paths
+3. optional type coercion is available by setting the type as a suffix:
+  1. Symbol: `__TYPESYM`
+  2. Boolean: `__TYPEBOOL`
+  3. Integer: `__TYPEINT`
+  4. JSON: `__TYPEJSON`
+  5. JSON with symbole keys: `__TYPEJSONSYM`
+4. underscores are handled in paths by using camelCase starting with a lowercase letter where an underscore is inserted before each uppercase letter
+
+```
+LITA_ROBOT_NAME=Configbot          # config.robot.name = 'Configbot'
+LITA_ROBOT_LOCALE__TYPESYM=en      # config.robot.locale = :en
+LITA_ROBOT_logLevel__TYPESYM=info  # config.robot.log_level = :info
+```
+
+### lita_config.rb
+
+```ruby
+Lita.configure do |config|
+  config = Lita::Extensions::DotenvConfig.new(config).config
+end
+```
