+## Native Electron App
+
+### Download
+
+Besides the web version we also deliver a native Electron app to download and run on a local machine. This app also offers a "Safe for Offline Usage" feature which allows to download data and view it later without an internet connection.
+
+The native app releases can be downloaded in the GitHub repo's "release" section or directly from:
+
+- Windows `https://storage.googleapis.com/esa-cfs-versions/electron/master/esa-climate-from-space-${VERSION}-win.exe`
+- MacOs `https://storage.googleapis.com/esa-cfs-versions/electron/master/esa-climate-from-space-${VERSION}-mac.zip`
+- Linux `https://storage.googleapis.com/esa-cfs-versions/electron/master/esa-climate-from-space-${VERSION}-linux.zip`
+
+Note: Be sure to replace the `VERSION` number e.g. (`0.4.0` -> `https://storage.googleapis.com/esa-cfs-versions/electron/develop/esa-climate-from-space-0.4.0-win.exe`)
+
