 # ultimate-guitar-mytabs
-Browser script to scrape and download your saved UltimateGuitar tabs to CSV/JSON
+
+This browser script allows you to scrape and download your saved UltimateGuitar tabs to JSON format.
+
+There are two ways to use this script:
+
+1. Install it as a Greasemonkey script (or whatever extension you use for custom UserScript).
+   Every time you browse to your UltimateGuitar page, the Download button will appear next to
+   the header.
+
+2. Manually paste the code in the browser developer console - the button will be added on the
+   fly. You can also manually call `getTabs` from the developer console to access, filter
+   and manipulate the list of objects.
+
+![Screenshot](https://i.ibb.co/WPmwQbT/837c447a43af.png)
+
+Note that the script will download all the tabs on the current page. If you want to download all
+of your tabs, then select _All_ from the top filter. The current order of the tabs on the page is
+also preserved in the downloaded JSON.
