1. If your system's CPU architecture is not x86\_64, the version of Chromium bundled with Puppeteer will not work, and the following steps are required:
1. Install Chrome/Chromium from your distribution's package manager
1. Set `executable_path` in `puppet/config.json` to the path to the installed Chrome/Chromium binary
1. Run `node prep_helper.js` to open Chrome/Chromium with the downloaded LINE extension enabled, and click on the LINE icon next to the URL bar
1. Once the LINE popup appears, press F12 to show DevTools, which will reveal the LINE extension's UUID
1. Edit `puppet/config.json` with some important settings:
* set `"url"` to the UUID found in the previous step
* set the `"listen"` settings to the socket to use for communication with the bridge (see [puppet/README.md](puppet/README.md) for details)
1. Edit `puppet/config.json` with desired settings (see [puppet/README.md](puppet/README.md) for details)
## Bridge
1. `cd` to the project root directory and create a Python virtual environment with `python3 -m venv .venv`, and enter it with `source .venv/bin/activate`
