+## Building
+
+You need either [Docker](https://github.com/docker/docker) and
+``make``, or `go` and `godep` in order to build traefik.
+
+### Using Docker and Makefile
+
+You need to run the ``binary`` target. This will create binaries for
+linux and darwin platforms in the `dist` folder.
+
+```bash
+$ make binary
+docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
+# […]
+docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/vincent/src/github/vdemeester/traefik/dist:/go/src/github.com/emilevauge/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate binary
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: binary (in .)
+Number of parallel builds: 8
+
+-->       linux/arm: github.com/emilevauge/traefik
+-->    darwin/amd64: github.com/emilevauge/traefik
+-->      darwin/386: github.com/emilevauge/traefik
+-->       linux/386: github.com/emilevauge/traefik
+-->     linux/amd64: github.com/emilevauge/traefik
+
+$ ls dist/
+traefik*  traefik_darwin-386*  traefik_darwin-amd64*  traefik_linux-386*  traefik_linux-amd64*  traefik_linux-arm*
+```
+
+### Using `godep`
+
+The idea behind `godep` is the following :
+
+- when checkout(ing) a project, **run `godep restore`** to install
+  (`go get …`) the dependencies in the `GOPATH`.
+- if you need another dependency, `go get` it, import and use it in
+  the source, and **run `godep save ./...` to save it in
+  `Godeps/Godeps.json` and vendoring it in `Godeps/_workspace/src`.
+
+```bash
+$ godep restore
+# Simple go build
+$ godep go build
+# Using gox to build multiple platform
+$ GOPATH=`godep path`:$GOPATH gox "linux darwin" "386 amd64 arm" \
+    -output="dist/traefik_{{.OS}}-{{.Arch}}"
+# run other commands like tests
+$ godep go test ./...
+ok      _/home/vincent/src/github/vdemeester/traefik    0.004s
+```
+
+## Tests
+
+You can run unit tests using the `test-unit` target and the
+integration test using the `test-integration` target.
+
+```bash
+$ make test-unit
+docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
+# […]
+docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/vincent/src/github/vdemeester/traefik/dist:/go/src/github.com/emilevauge/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: test-unit (in .)
++ go test -cover -coverprofile=cover.out .
+ok      github.com/emilevauge/traefik   0.005s  coverage: 4.1% of statements
+
+Test success
+```
