 - **Temporary**: Set these environment variables in your shell before running the tests. This is the easiest way to get started, but you'll have to set them every time you open a new terminal.
 - **Reusable**: If you anticipate developing for multiple sessions, set these environment variables in your shell profile (like `~/.bashrc` or `~/.zshrc`). This way, you won't have to set them every time you open a new terminal.
 
-The environment variables you'll need to set for each adapter are:
-
-```bash
