+# Help
+
+We all need a little help sometimes. Don't let a few roadblocks stand in the way
+of you building something awesome.
+
+## Community Support
+
+If you're a developer looking to contribute code, documentation, or discussion;
+we are more than happy to help provide clarification and answer questions via
+[GitHub issues][gh-issues] or our [community forum][google-group]. Regular
+contributors may also be invited to join our Slack Group to streamline
+discussion.
+
+For bug reports and feature requests (including incomplete or confusing
+documentation), [GitHub issues][gh-issues] continue to be your best avenue of
+communication.
+
+Complex issues specific to your organization/situation are still okay to post,
+but they're less likely to receive a response. Unfortunately, we have limited
+resources and must be judicious with how we allocate them. If you find yourself
+in this situation and in need of assistance, it may be in your best interest to
+persue paid support.
+
+## Commercial Support
+
+The Open Health Imaging Foundation does not offer commercial support, however,
+some community members do offer consulting services. You can search our
+[Community Forum](https://community.ohif.org/) for more information.
