You bought a desktop app that already works, so that the app you actually want to build starts from a running window instead of an empty folder.
This page is the map. Read it once before you touch anything.
Measured on a clean clone, not estimated:
The systems that are done, wired, and running:
Fifteen screens ship so you can see each system working. Most of them are examples, not your product. Delete them as you replace them.
Keep these until you have your own version: Settings , License , About , Logs . They are real app surfaces your users will expect.
Treat these as reference and delete them: Counter , Explorer , Notes , Batch , Demo , UI , Keys , Sign-in , AI , Claude .
Each one lives in a single folder under src/features/ , and every screen is registered in one file, so deleting a demo is deleting a folder and one line.
Nobody can do these for you, so plan for them:
You do not need Electron experience. You do need to be comfortable with basic React.
Get the Code then Run It on Your Computer . Together they take about ten minutes.
