+We welcome contributions in the form of issues and pull requests.  We view the contributions and process as the same for internal and external contributors.
+
+## Issues
+
+Log issues for both bugs and enhancement requests.  Logging issues are important for the open community.
+
+Issues in this repository should be for the toolkit packages.  Runner specific issues can be filed [in the runner repository](https://github.com/actions/runner).
+
+## Enhancements and Feature Requests
+
+We ask that before significant effort is put into code changes, that we have agreement on taking the change before time is invested in code changes. 
+
+1. Create a feature request. 
+2. When we agree to take the enhancement, create an ADR to agree on the details of the change.
+
+An ADR is an Architectural Decision Record.  This allows consensus on the direction forward and also serves as a record of the change and motivation. [Read more here](../docs/adrs/README.md).

+## Development Life Cycle

+# ADRs
+
+ADR, short for "Architecture Decision Record" is a way of capturing important architectural decisions, along with their context and consequences.
+
+This folder includes ADRs for the actions toolkit. ADRs are proposed in the form of a pull request, and they commonly follow this format:
+
+* **Title**: short present tense imperative phrase, less than 50 characters, like a git commit message.
+
+* **Status**: proposed, accepted, rejected, deprecated, superseded, etc.
+
+* **Context**: what is the issue that we're seeing that is motivating this decision or change.
+
+* **Decision**: what is the change that we're actually proposing or doing.
+
+* **Consequences**: what becomes easier or more difficult to do because of this change.
