 ## Dev Setup
 
-Make sure you have Docker installed and running.
+The recommended way is to use the main `Makefile` that runs everything inside a container.
+
+If you don't have or want to use Docker for building you need to make sure you have all the needed tools installed locally:
+
+* go 1.14
+* `go get github.com/golang/protobuf/protoc-gen-go@v1.4.1`
+* `go get golang.org/x/tools/cmd/goimports`
+* `go get gotest.tools/gotestsum@v0.4.2`
+* `go get github.com/golangci/golangci-lint/cmd/golangci-lint@v1.26.0`
+
+And then you can call the same make targets but you need to pass it the `builder.Makefile` (`make -f builder.Makefile`).
