+
+1. Fork a copy of this repo
+2. Checkout your copy of the repo to your local computer
+3. Uncomment the `//var dashboardplus_base_uri = chrome.extension.getURL('');` code in `script.js` so files are loaded locally.
+3. Disable the real Dashboard Plus extension in Google Chrome
+4. Click "Developer Mode" at the top of the Google Chrome extension page
+5. Click "Load Unpacked Extension" and select the git checkout folder 
+6. This should load your own local copy of the extension into Google Chrome
+7. Edit the files and use the "Reload" button on the Extension page to test the changes.
+8. Once happy with changes, commit them back to your git repo, then do a pull request so I can merge those changes into this repo for everyone.
