-3. Login to the Red Hat Registry: `docker login registry.redhat.io` using your Customer Portal credentials.
+3. Ensure the `tar.gz` file is in the `downloads` directory
 4. Run `make build-advancedserver`
 
-> **Warning**: Note that from MQ 9.2.X CD, the MQ container build uses a 'No-Install' MQ Package, available under `IBM MQ V9.2.x Continuous Delivery Release components eAssembly, part no. CJ7CNML`

 If you have an MQ archive file with a different file name, you can specify a particular file (which must be in the `downloads` directory).  You should also specify the MQ version, so that the resulting image is tagged correctly, for example:
