-### 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
-```
