I installed the IBM Liberty Developer Tools in eclipse, but Websphere Liberty is not showing up in the server tab. Any suggestions on how to fix this?

That article is a little out of date with how things are currently set up. If you want to use Open Liberty you need the developer tools from the Open Liberty site https://openliberty.io/downloads/#eclipse_developer_tools , not the Eclipse Marketplace - that one is for commercial versions of Liberty.
