 # QLArrow
 
-QuickLook plugin for [Arrow](https://arrow.apache.org/)
+[QuickLook](https://support.apple.com/guide/mac-help/view-and-edit-files-with-quick-look-mh14119/mac) plugin for various [Arrow](https://arrow.apache.org/) file formats.
+[Arrow](https://arrow.apache.org/) is a high-performance, language-agnostic columnar memory format.
+
+## Roadmap
+
+[Parquet](https://parquet.apache.org/) is the main use case here but [Arrow IPC](https://arrow.apache.org/docs/format/Columnar.html) may be useful for some.
+
+Currently, [QLArrow](https://github.com/amoeba/QLArrow) provides [QuickLook](https://support.apple.com/guide/mac-help/view-and-edit-files-with-quick-look-mh14119/mac) previews for:
+
+- [x] [Parquet](https://parquet.apache.org/)
+- [ ] Feather
+- [ ] Arrow IPC
