# Contributing ### Building You need either [Docker](https://github.com/docker/docker) and `make`, or `go` and `glide` in order to build traefik. #### Setting up your `go` environment - You need `go` v1.5 - You need to set `export GO15VENDOREXPERIMENT=1` environment variable - You need `go-bindata` to be able to use `go generate` command (needed to build) : `go get github.com/jteeuwen/go-bindata/...`. - If you clone Træfɪk into something like `~/go/src/github.com/traefik`, your `GOPATH` variable will have to be set to `~/go`: export `GOPATH=~/go`. #### Using `Docker` and `Makefile` You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder. ```bash $ make binary docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .
