+# Installation
+
+Installation will copy itself to `C:\windows\bridge.exe` and create a Windows service.  
+Logs are stored in `C:\windows\logs\bridge.log`.
+
+## Preparing macOS for Installation
+
+Before proceeding with the installation, you need to set up a **LaunchAgent** due to the way `$TMPDIR` works on macOS.
+
+- Download the latest build from the [releases](https://github.com/EnderIce2/rpc-bridge/releases).
+- Open the archive and make the `launchd.sh` script executable by doing: `chmod +x launchd.sh`.
+- To **install** the LaunchAgent, run `./launchd.sh install` and to **remove** it simply run `./launchd.sh remove`.
+
+The script will add a LaunchAgent to your user, that will symlink the `$TMPDIR` directory to `/tmp/rpc-bridge/tmpdir`.

+## Run without installing the service
+
+If you prefer not to use the service, you can manually run `bridge.exe` within the prefix, and click on `Start` in the GUI.
