# How to contribute to Tink

If you'd like to talk to the developers or get notifications about major product
updates, subscribe to our [mailing
list](https://groups.google.com/forum/#!forum/tink-users).

As new features are developed, it's helpful to understand who is using Tink and
how. Consider taking this [survey](https://docs.google.com/forms/d/1mhHvyNJQgTXFDnqOermB7-BD8GQSyvtFPUAhILRbYcA/)
to provide feedback about your deployment.

You're also welcome to [report bugs or file feature
requests](https://github.com/google/tink/issues/new/choose). See
the sections below for submitting patches and contributions to this project.
