current version: https://documentation.magnolia-cms.com/display/DOCS60/Creating+a+custom+bundle
=> The version is not wrong or super outdated, but there are a few things which we should change when compared to the current 6.0 version and all older versions which are similar:

• It proposes to take the empty-webapp as base. That's sometimes fine but rather as an exception.
  Instead we the first choices should be magnolia-community-webapp or magnolia-enterprise-pro-webapp
  • Generally we should explain all possibilities as proposed by the created pom files, which are:
    • magnolia-empty-webapp
    • magnolia-community-webapp
    • magnolia-enterprise-standard-webapp
    • magnolia-enterprise-pro-webapp
• No more screenshots from IDE windows
• Show better ways how to start the custom webapp
