 # This docker file can be used in kubernetes. 
 # It accepts all cluster related parameters at run time. 
 # It means it's very easy to add new containers to the cluster 
+#
+# Usage:
+#
+# 1. AntMediaServer: Specify the name of the Ant Media Server zip file to complete the installation.
+# --build-arg AntMediaServer='ant-media-server.zip'
+#
+# 2. LicenseKey: Assign your license key to this variable to complete the installation without needing a zip file. 
+# --build-arg LicenseKey='your-license-key'
+#
+# 3. InstallMediaPush: Set this variable to 'true' to enable headless Chrome on the server for recording and streaming web pages back to Ant Media Server.
+# --build-arg InstallMediaPush='true'
