docs(README): remove the build from source instructions

docs/developers.md already has these instructions. And 80% of the time
someone looking at this project is interested in getting started not
hacking directly.

-
-### Install from source
-
-To install Helm from source, follow this process:
-
-Make sure you have the prerequisites:
-- Go 1.6
-- A running Kubernetes cluster
-- `kubectl` properly configured to talk to your cluster
-- [Glide](https://glide.sh/) 0.10 or greater with both git and mercurial installed.
-
-1. [Properly set your $GOPATH](https://golang.org/doc/code.html)
-2. Clone (or otherwise download) this repository into $GOPATH/src/k8s.io/helm
-3. Run `make bootstrap build`
-
-You will now have two binaries built:
-
-- `bin/helm` is the client
-- `bin/tiller` is the server
-
-From here, you can run `bin/helm` and use it to install a recent snapshot of
-Tiller. Helm will use your `kubectl` config to learn about your cluster.
-
-For development on Tiller, you can locally run Tiller, or you build a Docker
-image (`make docker-build`) and then deploy it (`helm init -i IMAGE_NAME`).
-
-The [documentation](docs) folder contains more information about the
-architecture and usage of Helm/Tiller.
