Documentation for Couchbase Server from Azure Marketplace - Reinstall options

Is there any updated documentation for installing Couchbase Server from Azure Marketplace. The documentation at Deploy Couchbase Server Using Azure Marketplace | Couchbase Docs is not accurate.
I am particularly interested in how to do a reinstall of Couchbase when the initial install was from an AzureMarketplace image.
I had a three node cluster but would like to do a complete reinstall.
