+## Installation from source

 Build the code (make sure you have set GOPATH):
 ```
 go get -d k8s.io/kops
+git checkout release
 cd ${GOPATH}/src/k8s.io/kops/
 make
 ```
 
+* The `release` branch is where releases are taken from.  This is the stable code branch.
+* The `master` branch  _should_ also be functional, but is where active development happens, so may be less stable.

 (Note that the code uses the relatively new Go vendoring, so building requires Go 1.6 or later,
 or you must export GO15VENDOREXPERIMENT=1 when building with Go 1.5.  The makefile sets
 GO15VENDOREXPERIMENT for you.  Go code generation does not honor the env var in 1.5, so for development

+## Branch strategy
+
+We develop on the master branch.  The master branch is expected to build and generally to work,
+but has not necessarily undergone the more complete validation that a release would.  The `release`
+branch is expected to always be stable.
+
+We tag releases as needed from the `release` branch and upload them to github.
+
+We occasionally batch merge from the master branch to the `release` branch.  We don't maintain
+multiple release branches as we expect most people to upgrade kops to the latest version.  We also
+don't (yet) do lots of cherry-picking for that reason.
+
+The intention is that this allows for development velocity, while also allowing for stable releases.
