+## F.A.Q.
+
+### What languages are supported for fixes?
+Currently we support codemods for Java and Python. Stay tuned for additional language support at https://pixee.ai!
+
+### What happens to my code?
+The Pixee CLI currently runs most detection and fixes locally to your own host machine. Any features that require network access to a third-party service (e.g. OpenAI) will require explicit opt-in. We promise to be transparent when this is the case.
+
+### How can I install the GitHub application?
+Get the most out of Pixee by installing the Pixeebot GitHub app at https://app.pixee.ai. Or find us on [GitHub Marketplace](https://github.com/apps/pixeebot).
+
+### Where can I request features and report issues?
+For CLI feature requests and bug reports please use our GitHub issue tracker: https://github.com/pixee/pixee-cli/issues
