+Often, it's very useful to inject transactions from Fiber into your local mempool.
 
 Fiber offers a Docker image that allows users to do that.
 
 ## Usage
+
 ```bash
-docker run --name fiber-inject mempirate/fiber-inject \
+docker run --name fiber-inject ghcr.io/chainbound/fiber-inject:latest-arm64 \
     fiber-inject \
     --fiber-api $API_ENDPOINT \
     --fiber-key $YOUR_API_KEY \
-    --enodes $ENODE1,$ENODE2
+    --enodes $ENODE1,$ENODE2 \
+    --port 30303
 ```
+
 This will subscribe to the Fiber transaction stream and broadcast all the transactions it receives
 to your local nodes (specified by `--enodes`, provided they're connected).
 
 Your local `enode`'s IP address should either be the gateway address of your Docker network (usually `172.17.0.1`), or one of the publicly reachable
 IP addresses of your machine.
 
+The default port number is 30303 (the default p2p port of Ethereum nodes), but you can change it with the `--port` flag.
+
+We offer a pre-built Docker image for both `arm64` and `amd64` architectures (under the `latest-arm64` and `latest-amd64` tags respectively).
+
 ## Troubleshooting
-It's possible that your local node has reached its maximum amount of peers, and therefore won't accept Fiber inject as another peer.

 ### Add Fiber inject as a trusted peer
+
 #### 1. Expose the p2p port of the Docker container
+
 :::info
 Make sure the mapped port isn't already taken by your local node.
