+# Contributing to Vanadium
+
+Vanadium is an open source project.
+
+It is the work of many contributors. We appreciate your help!
+
+
+## Filing issues
+
+We use a single GitHub repository for
+[tracking all issues](https://github.com/vanadium/issues/issues)
+across all Vanadium repositories.
+
+
+## Contributing code
+
+Please read the
+[Contribution Guidelines](https://github.com/vanadium/docs/blob/master/community/contributing.md)
+before sending patches.
+
+**We do not accept GitHub pull requests**
+(we use [Gerrit](https://www.gerritcodereview.com/) instead for code review).
+
+Unless otherwise noted, the Vanadium source files are distributed under
+the BSD-style license found in the LICENSE file.
