+# Envy
+
+**Envy** loads and sets environment variables from YAML. It supports all YAML data types, including arrays and hashes.
+
+*Envy* uses the YAML key mapping of a value as the environment variable name. For example, the following YAML configuration...
+
+```yaml
+---
+app:
+  database:
+    host: localhost
+    port: 4321
+  server:
+    hosts:
+      - localhost
+      - grottopress.localhost
+    port: 8080
+  webhooks:
+    - url: "https://example.com"
+      token: "a1b2c2"
+    - url: "https://myapp.net"
+      token: "d4e5f6"
+```
+
+...sets environment variables as follows:
+
+```ruby
+ENV["APP_DATABASE_HOST"] = "localhost"
+ENV["APP_DATABASE_PORT"] = "4321"
+
+ENV["APP_SERVER_HOSTS_0"] = "localhost"
+ENV["APP_SERVER_HOSTS_1"] = "grottopress.localhost"
+ENV["APP_SERVER_PORT"] = "8080"
+
+ENV["APP_WEBHOOKS_0_URL"] = "https://example.com"
+ENV["APP_WEBHOOKS_0_TOKEN"] = "a1b2c2"
+ENV["APP_WEBHOOKS_1_URL"] = "https://myapp.net"
+ENV["APP_WEBHOOKS_1_TOKEN"] = "d4e5f6"
+```
+
+*Envy* loads environment variables only once per application life-cycle. This avoids the overhead of reading and parsing YAML files on every single request.
+
+It sets file permission (`0600` by default) for all config files.
+
+*Envy* supports loading a file from a supplied list of files in decreasing order of priority; the first readable file is loaded.
+
+## Installation
+
+Install the gem and add to the application's Gemfile by executing:
+
+```
+bundle add envy --git=https://github.com/GrottoPress/envy.rb
+```
+
+If bundler is not being used to manage dependencies, install the gem by executing:
+
+```
+# Clone repository
+git clone https://github.com/GrottoPress/envy.rb.git ./envy
+
+# Change to the envy directory
+cd ./envy
+
+# Build gem
+gem build envy.gemspec -o envy.gem
+
+# Install gem
+gem install envy.gem
+```
+
+## Usage
+
+- Load the first readable file from a supplied list of files. Optionally set files permissions. This does *not* overwrite existing environment variables:
+
+    ```ruby
+    require "envy"
+
+    Envy.from_file ".env.yml", ".env.dev.yml", perm: 0o400
+    ```
+
+ - Load the first readable file from a supplied list of files. Optionally set files permissions. This *overwrites* existing environment variables:
+
+    ```ruby
+    require "envy"
+
+    Envy.from_file! ".env.yml", ".env.dev.yml", perm: 0o400
+    ```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+
+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 the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
