Provide simpler and clearer options to install Knative for prototyping purposes

How Might We...

provide simpler options to install Knative for prototyping purposes?

For...

New Users

So that...

Users who are new to Knative can easily spin up our software, understand what they are installing, and begin to prototype for demo purposes.

Rationale

This is one of the main findings from user research presented at the Round 1 Research Shareout

Potential Metrics

• Exit Rates each stage of the Knative Install (lower is better)
• # of StackOverflow Questions in a given period (higher is better)
• # of new Users in the Knative Slack in a given period (higher is better)
• Average rating for "Getting Started" w/ Serving + Eventing from users

Main Potential Features List (Feature ideas that do not appear here are not tracked and, therefore, do not exist)

• Split Knative install into multiple pages to assist in tracking drop-off rates
  ^^See Split install/any-kubernetes-cluster/ into multiple pages  #11^^
• Change the /install/ page to have clear sub-headings for each installation method, as well as some context for each
  ^^See Update knative/docs/install with clear sub-headings for each section #12^^
• Add Context to each of the steps in the YAML-based installation
  ^^ See Improve context for each of the steps of the YAML-based install  #26 ^^
• Make Optional steps collapsable in the YAML-based installation
  ^^ See https://github.com/knative/docs/issues/3374^^
• Add a "Call to Action" at the end of the Knative install which points to Slack + Stack Overflow as Support channels
• Create and maintain a list of community projects which help users "Get Started" (konk, mink, etc.) in the UX Repo, link to it from the Knative site
• Create and maintain a "knative-awesome.md" file in the UX repo which showcases different usages of Knative, link to it from the Knative site
• Provide a clear recommendation for a networking layer to be used for prototyping purposes
• Add Hello World Samples in a data table ordered by programming language at the end of Install (allow toggle of page based on desired programming language with a dropdown)
