Write down 1.0 and 2.0 plans.
+## Guidelines
+
+1. Rusoto [has a CHANGELOG](CHANGELOG.md) to track what's in releases.
+2. Releases are tracked [in GitHub](https://github.com/rusoto/rusoto/releases).
+
+Before hitting 1.0, the API has no backwards compatible guaranteed.

+After 1.0, the API will be stable for the 1.0 releases. If we need to break the API, Rusoto 2.0 will be started. Patches will be back ported to the 1.x branch.
