+Envy makes working with ENV variables in Go trivial.
+
+* Get ENV variables with default values.
+* Set ENV variables safely without affecting the underlying system.
+* Temporarily change ENV vars; useful for testing.
+* Map all of the key/values in the ENV.
+* Loads .env files (by using [godotenv](https://github.com/joho/godotenv/))
+* More!
+
+## Installation
+
+```text
+$ go get -u github.com/gobuffalo/envy
+```
+
+## Usage
+
+```go
+func Test_Get(t *testing.T) {
+	r := require.New(t)
+	r.NotZero(os.Getenv("GOPATH"))
+	r.Equal(os.Getenv("GOPATH"), envy.Get("GOPATH", "foo"))
+	r.Equal("bar", envy.Get("IDONTEXIST", "bar"))
+}
+
+func Test_MustGet(t *testing.T) {
+	r := require.New(t)
+	r.NotZero(os.Getenv("GOPATH"))
+	v, err := envy.MustGet("GOPATH")
+	r.NoError(err)
+	r.Equal(os.Getenv("GOPATH"), v)
+
+	_, err = envy.MustGet("IDONTEXIST")
+	r.Error(err)
+}
+
+func Test_Set(t *testing.T) {
+	r := require.New(t)
+	_, err := envy.MustGet("FOO")
+	r.Error(err)
+
+	envy.Set("FOO", "foo")
+	r.Equal("foo", envy.Get("FOO", "bar"))
+}
+
+func Test_Temp(t *testing.T) {
+	r := require.New(t)
+
+	_, err := envy.MustGet("BAR")
+	r.Error(err)
+
+	envy.Temp(func() {
+		envy.Set("BAR", "foo")
+		r.Equal("foo", envy.Get("BAR", "bar"))
+		_, err = envy.MustGet("BAR")
+		r.NoError(err)
+	})
+
+	_, err = envy.MustGet("BAR")
+	r.Error(err)
+}
+```
+## .env files support
+
+Envy now supports loading `.env` files by using the [godotenv library](https://github.com/joho/godotenv/).
+That means one can use and define multiple `.env` files which will be loaded on-demand. By default, no env files will be loaded. To load one or more, you need to call the `envy.Load` function in one of the following ways:
+
+```go
+envy.Load() // 1
+
+envy.Load("MY_ENV_FILE") // 2
+
+envy.Load(".env", ".env.prod") // 3
+
+envy.Load(".env", "NON_EXISTING_FILE") // 4
+
+// 5
+envy.Load(".env")
+envy.Load("NON_EXISTING_FILE")
+
+// 6
+envy.Load(".env", "NON_EXISTING_FILE", ".env.prod")
+```
+
+1. Will load the default `.env` file
+2. Will load the file `MY_ENV_FILE`, **but not** `.env`
+3. Will load the file `.env`, and after that will load the `.env.prod` file. If any variable is redefined in `. env.prod` it will be overwritten (will contain the `env.prod` value)
+4. Will load the `.env` file and return an error as the second file does not exist. The values in `.env` will be loaded and available.
+5. Same as 4
+6. Will load the `.env` file and return an error as the second file does not exist. The values in `.env` will be loaded and available, **but the ones in** `.env.prod` **won't**.

By doing this it means you can be guaranteed that Packr can find your files correctly, even if you're not running in the directory that the box was created in.

+## Building/Moving a portable release
+
+When it comes to building multiple releases you typically want that release to be built in a specific directory.
+
+For example: `./releases`
+
+However, because passing a `.go` file requires absolute paths, we must compile the release in the appropriate absolute path.
+
+```bash
+GOOS=linux GOARCH=amd64 packr build
+```
+
+Now your `project_name` binary will be built at the root of your project dir. Great!
+
+All that is left to do is to move that binary to your release dir:
+
+Linux/macOS/Windows (bash)
+
+```bash
+mv ./project_name ./releases
+```
+
+Windows (cmd):
+
+```cmd
+move ./project_name ./releases
+```
+
+Powershell:
+
+```powershell
+Move-Item -Path .\project_name -Destination .\releases\
+```
+
+If you _target_ for Windows when building don't forget that it's `project_name.exe`
+
+Now you can make multiple releases and all of your needed static files will be available!
+
+#### Summing it up:
+
+Example Script for building to 3 common targets:
+
+```bash
+GOOS=darwin GOARCH=amd64 packr build && mv ./project_name ./releases/darwin-project_name \
+  && GOOS=linux GOARCH=amd64 packr build && mv ./project_name ./releases/linux-project_name \
+  && GOOS=windows GOARCH=386 packr build && mv ./project_name.exe ./releases/project_name.exe \
+  && packr clean
+```

 ## Debugging
 
 The `packr` command passes all arguments down to the underlying `go` command, this includes the `-v` flag to print out `go build` information. Packr looks for the `-v` flag, and will turn on its own verbose logging. This is very useful for trying to understand what the `packr` command is doing when it is run.
