1. This assumes, you have already setup DNN 7.4.2 and 2sxc for development
  2. Git clone https://github.com/2sic/2sxc-inpage to c:\Projects\2sxc-inpage\
  3. Open it in VS code, and In that folder, run npm ci - you should have a bunch of packages installed
  4. See if you can build it, using the vs-code run (ctrl+shift+P > Run > npm: dev)
