Here it is for brevity, but I'm unlikely to update these steps here, just on the readme:
Preliminary step: log into https://claude.ai, if you aren't already Go to a page where you want to have a user script, e.g. https://example.org Hit the extension button Claude.ai opens in a new tab, and it has access to an MCP Ask Claude to, for example, "make a user script to turn the background green" Claude goes off, it will write the scripts, and instruct you to refresh example.org once done
