 On Windows, we recommend [Windows Powershell](https://docs.microsoft.com/en-us/powershell/scripting/overview?view=powershell-7) (built in to Win10). On Mac, use the basic terminal or, even better, [iTerm2](https://www.iterm2.com/). On Linux (or if you're using WSL2 on Windows), the default Linux Shell (such as [Bash](https://www.gnu.org/software/bash/)) is a great choice.

 1. If your computer has an Apple Silicon (M1 or M2) chip, then you should modify the `platform` line in the `docker-compose.yml`, changing it to `linux/arm64`.
 1. Modify the `MAPBOX_API_KEY`, `GOOGLE_MAPS_API_KEY`, and `GOOGLE_MAPS_SECRET` lines in the `docker-compose.yml` using the keys and secret you've acquired.
 1. Modify the `SIDEWALK_CITY_ID` line in the `docker-compose.yml` to use the ID of the appropriate city, listed [here](https://github.com/ProjectSidewalk/SidewalkWebpage/wiki/Docker-Troubleshooting#first-heres-a-table-that-youll-reference-when-setting-up-your-dev-env) (it's the city that matches your database dump, so check the name of the db dump file).
