 ### Use a vendor tool like [Govendor](https://github.com/kardianos/govendor)
 1. `go get` govendor
 ```sh
 $ go get github.com/kardianos/govendor
 ```
 2. Create your project folder and `cd` inside
 ```sh
 $ mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_"
 ```
 If you are on a Mac and you're installing Go 1.8 (released: Feb 2017) or later, GOPATH is automatically determined by the Go toolchain for you. It defaults to $HOME/go on macOS so you can create your project like this
 ```sh
 $ mkdir -p $HOME/go/src/github.com/myusername/project && cd "$_"
 ```
 3. Vendor init your project and add gin
 ```sh
 $ govendor init
 $ govendor fetch github.com/gin-gonic/gin@v1.3
 ```
 4. Copy a starting template inside your project
 ```sh
 $ curl https://raw.githubusercontent.com/gin-gonic/examples/master/basic/main.go > main.go
 ```
 5. Run your project
 ```sh
 $ go run main.go
 ```
