Download or unpack the extension
Use the release ZIP or build output and make sure you have the unpacked extension folder available on disk.
Open the extensions page
In Chrome, Brave, Edge, or another Chromium browser, open chrome://extensions.
Enable Developer mode
Turn on Developer mode so the browser shows manual extension loading controls.
Load the unpacked folder
Choose Load unpacked and select the extracted extension directory, not just the ZIP file itself.
Recommended
Use the built extension folder
If you build from this repo, the cleanest folder to load is dist/extension/.
Release artifact
ZIP is for download, not direct install
Browsers usually do not install the ZIP directly from a website. Extract it first, then load the folder manually.
Store later
Store install will be simpler
Once the store listing is live, users should prefer that route because it is trusted and updates cleanly.
