 # Turf
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/turf`. To experiment with that code, run `bin/console` for an interactive prompt.
+Turf lets you control the value of variables in different environments and makes it easy to override values locally.  It's easy to set `speak_in_chat` to `true` when `RAILS_ENV` equals "production" and `false` otherwise.  Turf is similar to the Rails `secrets.yml` file, but more powerful because it can execute Ruby code and return arrays, hashes, etc.
 
-TODO: Delete this and the text above, and describe your gem
 
-## Installation
+## How it works
 
-Add this line to your application's Gemfile:
+Turf looks for methods in the following order:
 
+1. The `Turf::Local` class.
+2. The `Turf::Test`, `Turf::Development`, or `Turf::Production` class.  Turf uses the development environment by default, but this can be overridden by setting `RAILS_ENV` to "production" or "test".
+3. The `Turf::Default` class.
+
+I recommend defining the Turf classes in the `/config/turf` directory.
+
+
+## Examples
+
 ```ruby
-gem 'turf'
-```
+ENV["RAILS_ENV"] = "production"
 
-And then execute:
+class Turf::Local
+  def something
+    "something in local"
+  end
+end
 
-    $ bundle
+class Turf::Development
+  def blah
+    "blah in development"
+  end
+end
 
-Or install it yourself as:
+class Turf::Production
+  def something
+    "something in production"
+  end
 
-    $ gem install turf
+  def blah
+    "blah in production"
+  end
+end
 
-## Usage
+class Turf::Default
+  def four
+    2 + 2
+  end
+end
 
-TODO: Write usage instructions here
+# Turf::Local is the first place Turf looks for a
+# matching method
+Turf.find(:something) # => "something in local"
 
-## Development
+# The RAILS_ENV is set to production, so Turf looks
+# in Turf::Production second if the method is not
+# found in Turf::Local
+# Turf::Development is ignored in production
+Turf.find(:blah) # => "blah in production"
 
-After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake rspec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+# Turf::Default is the last place to look
+Turf.find(:four) # => 4
 
-To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
+# Turf raises an exception when it can't find
+# a matching method
+Turf.find(:hi_there) # => raises an exception
+```
 
+## Setup
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'turf'
+```
+
+Require turf:
+
+```ruby
+require 'turf'
+```
+
+Create the `Turf::Local`, `Turf::Test`, `Turf::Development`, `Turf::Production`, and `Turf::Default` classes (you don't have to create all of them, just the ones you want).
+
+Use `Turf.find()` in your project.
