+Installing Snaggle
+==================
+
+1. Drag Snaggle to the Applications folder.
+
+2. Open it. macOS will say Snaggle "is not opened because it is from an
+   unidentified developer" (or cannot be verified). This is expected: Snaggle is
+   free software and is not signed with a paid Apple Developer certificate.
+
+3. Open System Settings > Privacy & Security, scroll down to Security, and click
+   "Open Anyway" next to the message about Snaggle. Confirm with your password
+   or Touch ID.
+
+   (Control-clicking the app and choosing Open no longer works on macOS 15 and
+   later - Apple removed that shortcut.)
+
+4. Snaggle needs Screen Recording permission to capture anything. The first
+   capture triggers the request; enable Snaggle under
+   System Settings > Privacy & Security > Screen Recording, then quit and
+   reopen the app.
+
+Snaggle lives in the menu bar, not the Dock - look for the viewfinder icon.
+
+Prefer the terminal? This removes the quarantine flag in one step:
+
+   xattr -dr com.apple.quarantine /Applications/Snaggle.app
+
+Snaggle is free software under the GNU GPL v3. Source: <add your repository URL>
