+## Local Development Fork
+
+To edit this generator for your own purposes, theres just a couple steps.
+1. Clone the repo to a local folder (easy to do with the github desktop app, or via cli)
+2. Open the repo in your favourite code editor, and open a terminal of sorts.
+3. Run `npm i` to install all the dependencies and to acquire the node modules required to run it.
+4. When that is finished, run `npm start` or `npm run start` to run the program.
+5. Enjoy the chaos that is the JSON generator. (I'm not kidding)
