Install Caddie

It isn't in the Chrome Web Store yet, so this is the manual route. Five minutes, and you'll need a GHIN number.

1. Unzip it somewhere permanent

   Your Downloads folder works, but Chrome loads the extension from wherever you put this folder and reads it from there every time it starts. If you delete or move it later, Caddie disappears. Somewhere like ~/Documents/caddie is a safer bet.

2. Open the extensions page

   Paste chrome://extensions into your address bar. Links to it don't work — Chrome blocks them — so it has to be pasted or typed.

3. Turn on Developer mode

   Toggle at the top right of that page. This is what allows an extension that isn't from the store.

4. Load unpacked

   Button appears at the top left once Developer mode is on. Select the unzipped folder — the one containing manifest.json, not the .zip.

5. Sign in with GHIN

   Click the Caddie icon in your toolbar (you may need the puzzle-piece menu to pin it) and enter the email or GHIN number you use for the GHIN app. It's encrypted and stays on your machine.

6. Start on your own profile

   Open your own LinkedIn profile and press Verify me. That links your GHIN so other people see you as verified — and it's the one thing that makes Caddie work for someone who hasn't signed in yet.
