 ## Setup for Development
 
-In MacOS, install [homebrew](https://brew.sh). Then, use it to install Python 3.7 (*not* 3.8) with `brew install python3`. Ensure it is linked in your path (`brew link python3`). You can always double-check that this is the correct version: `python --version` should show 3.7. Next, run the bootstrap file which will clone deoldify, download the colorizing models, and install all python requirements in a virtual environment.

To do this, first open the file `timeslide.spec` and ensure that the path to your homebrew version (Cellar'ed) `libpng16.16.dylib` is correct (slight modifications may be necessary depending on version number.)
