 for the game Morrowind, for MacOS. It provides universal binaries compatible with both

+`tes3mp-server` runs well only on Intel-based Macs.
 
-## Installation
+## Installation & Running
 To install, download the latest `.dmg` file from the GitHub Releases page. Open the file
 and drag the `.app` to your Applications folder.
 
+To run the client, just double-click the application.
+
+The first time you run the application, you may need to right-click the `.app` and
+select "Open" due to the app being unsigned. This process will prompt you to confirm
+that you really want to open the application. After doing this once, you should be able
+run the application normally.
+
+### Server
+To run the server on an Intel-based Mac, you'll need to open a terminal and run:
+```bash
+/Applications/TES3MP.app/Contents/MacOS/tes3mp-server
+```
+
 ## Building from Source
