First of all, thank you very much for this fantastic tool and project.

I think how to set it up locally in a project, for example a TypeScript one, is underdocumented. I just figured it out myself, but I think it should be better documented somewhere in the project documentation or the README.

The steps are not many, but they are not that obvious. You need to npm or pnpm install the CLI package; then you need to configure pnpm so it can build the dependencies for the package.

That may be confusing for some, and if you don't do it you just get this somewhat confusing message:

ast-grep shim file was executed. This file exists so that npm tries to create the binary. It should be replaced after the 'postinstall' script is executed.
