 - Auto generated.
 - Thin layer over the C API.
 - Doc comments retained (where supported by clang).
+- GPL version of FFmpeg (allows for x264 etc).
+
+### TODO
+
+- [ ] Expose more headers.
+- [ ] Ensure acceleration enabled in builds.
+- [ ] Expose platform specific headers.
+- [ ] Cleanup internal packages.
+

+### FAQ
+
+- Q: Why is FFmpeg statically bundled?
+  - A: The version of FFmpeg varies by platform, making a one-size fits all style binding difficult with the Go build
+    system and its lack of a build.go file.
+- Q: Why are the arm packages not built by CI?
+  - A: Ideally they would be. However, the free GitHub plan does not include arm builders.
+- Q: Why is library `xyz` not enabled?
+  - A: Libraries have been added on a as-needed basis. Feel free to create a PR enabling any additional libraries.
+- Q: I have some C code that I can't convert to Go, due to a missing binding feature
+  - A: Create an issue with a C sample, and we can go from there.
