⚙️ How to install

1
Download and unzip the file above

Extract the zip to a permanent location — Chrome will load the extension directly from this folder, so don't delete it.


2
Open Chrome's extension manager

Navigate to chrome://extensions in your address bar.


3
Enable Developer mode

Toggle the Developer mode switch in the top-right corner of the extensions page.


4
Load the unpacked extension

Click Load unpacked, then select the folder you extracted in step 1.


5
Disable the store version

If you have Cardstock installed from the Chrome Web Store, disable it to avoid running both at once. You can re-enable it after disabling the beta.

✓ Your settings and credentials are stored per-extension. You'll need to re-enter your API key the first time you open the beta.

⚠️ Things to know

!
Chrome will show a developer mode warning

When you open Chrome with an unpacked extension loaded, you may see a banner warning that "extensions in developer mode can harm your computer." This is a standard Chrome notice — dismiss it to continue.


!
Beta builds don't auto-update

When a new beta is available, you'll need to download the zip again and click the reload button on the extension card in chrome://extensions.


!
Features may be rough around the edges

Beta builds contain work-in-progress features that haven't been fully tested. If something breaks, hop in Discord and let us know.
