     Depending on your linux operating system, to install Octant v0.13.1, you can use either
-    ```
+    ```bash
     wget https://github.com/vmware-tanzu/octant/releases/download/v0.13.1/octant_0.13.1_Linux-64bit.deb

     rpm -i octant_0.13.1_Linux-64bit.rpm
     ```
 
 2. Export your kubeconfig path (file location depends on your setup) to environment variable $KUBECONFIG.
 
-    ```
+    ```bash
     export KUBECONFIG=/etc/kubernetes/admin.conf
     ```
 
-3. Build antrea-octant-plugin.
+3. Get corresponding antrea-octant-plugin binary from [Release Assets](https://github.com/vmware-tanzu/antrea/releases/tag/v0.8.1)
+based on your environment and move the binary to OCTANT_PLUGIN_PATH.
 
-    ```
-    cd plugins/octant

-4. Move antrea-octant-plugin to OCTANT_PLUGIN_PATH.
+    For example, you can get antrea-octant-plugin-linux-x86_64 if it matches your operating system and architecture.
 
-    ```
+    ```bash
+    wget -O antrea-octant-plugin https://github.com/vmware-tanzu/antrea/releases/download/v0.8.1/antrea-octant-plugin-linux-x86_64
+    # Make sure antrea-octant-plugin is executable, otherwise Octant cannot find it.
+    chmod a+x antrea-octant-plugin
     # If you did not change OCTANT_PLUGIN_PATH, the default folder should be $HOME/.config/octant/plugins.
-    mv antrea/plugins/octant/bin/antrea-octant-plugin $HOME/.config/octant/plugins/

+4. Start Octant as a background process with UI related environment variables.
 
-    ```
+    ```bash
     # Change port 80 according to your environment and set OCTANT_ACCEPTED_HOSTS based on your requirements

 Now, you are supposed to see Octant is running together with antrea-octant-plugin via URL http://(IP or $HOSTNAME):80.

+Note:
+1. In Antrea v0.8.1, the Traceflow UI is a separate Octant plugin called antrea-traceflow-plugin.
+Starting with v0.9.0, the Traceflow UI will be merged into antrea-octant-plugin. When deploying Octant as a Pod using
+image antrea/octant-antrea-ubuntu:v0.8.1, you already have access to the alpha version of the Traceflow UI.
+2. If you deploy Octant and the Antrea UI as a process, you cannot access the Traceflow UI for now when following the
+steps listed above (at least until the v0.9.0 release). However, you can still build the binary yourself with
+the command below, with the remaining steps being almost the same as the ones above.
+
+    ```bash
+    # You will find the compliled binary under folder antrea/plugins/octant/bin.
+    cd plugins/octant
+    make antrea-traceflow-plugin
+    ```
