 1. Pull the image.

 2. Create and run a container.
 
    ```bash
-   docker run -d -p 3000:3000 No-Cash-7970/txnDuck
+   docker run -d -p 3000:3000 ghcr.io/no-cash-7970/txnduck
    ```
 
     If you need to use a port other than 3000, use the following instead:
 
     ```bash
-    docker run -d -p [PORT]:3000 No-Cash-7970/txnDuck
+    docker run -d -p [PORT]:3000 ghcr.io/no-cash-7970/txnduck
     ```
 
     Replace `[PORT]` with the port number you would like to use. For example,
     use port 3001 instead of 3000:
 
     ```bash
-    docker run -d -p 3001:3000 No-Cash-7970/txnDuck
+    docker run -d -p 3001:3000 ghcr.io/no-cash-7970/txnduck
