-### Hi :wave:! This extension is currently waiting on a [new version](https://github.com/kamranahmedse/pennywise/releases) of Pennywise to work correctly. If you want to use this extension in the mean time, you'll need to compile Pennywise from source. See [here](https://github.com/alxwrd/open-with-pennywise/issues/2#issuecomment-453496922) and [here](https://github.com/alxwrd/open-with-pennywise/issues/2#issuecomment-457588958) for more details.
