 # Install all packages
 pnpm install
 
-# Set up the development environment
+# Set up the development environment (opens the environment variables wizard)
 pnpm dev:setup-env
 
 # Start the web client and backend
 pnpm dev

+Lapse relies on ffmpeg for its serverside video processing.
+You can install ffmpeg [from their website](https://ffmpeg.org/download.html) by downloading the appropriate ffmpeg binary for your operating system.
 To start and stop the development environment, use `pnpm dev:start-env` and `pnpm dev:stop-env` respectively.
 
 When developing, it's a good idea to re-compile all packages on the fly!
