+# Electron Course
+
+This is the example code from the following freeCodeCamp course: <ToBeDefined></ToBeDefined>
+
+It tackles setting up an electron app that displays system resource usages for your CPU, RAM and File-System
+- using react and typescript
+- with typesafe IPC communication
+- with a hide-to-tray functionality
+- with a custom menu-bar
+- with a custom window-frame
+
+It's tested using both E2E- (Playwright) and Unit-Tests (Vitest)
+
+If you find run into any errors please post them as an issue in this Repository.
+
+Have a nice day :)
