<!-- What is the benefit to the distribution?  Will the software we generate be improved? How will the process of creating Fedora releases be improved?
 
      Be sure to include the following areas if relevant:
      If this is a major capability update, what has changed?
          For example: This change introduces Python 5 that runs without the Global Interpreter Lock and is fully multithreaded.
      If this is a new functionality, what capabilities does it bring?
          For example: This change allows package upgrades to be performed automatically and rolled-back at will.
      Does this improve some specific package or set of packages?
          For example: This change modifies a package to use a different language stack that reduces install size by removing dependencies.
      Does this improve specific Spins or Editions?
          For example: This change modifies the default install of Fedora Workstation to be more in line with the base install of Fedora Server.
      Does this make the distribution more efficient?
          For example: This change replaces thousands of individual %post scriptlets in packages with one script that runs at the end.
      Is this an improvement to maintainer processes?
          For example: Gating Fedora packages on automatic QA tests will make rawhide more stable and allow changes to be implemented more smoothly.
      Is this an improvement targeted as specific contributors?
          For example: Ensuring that a minimal set of tools required for contribution to Fedora are installed by default eases the onboarding of new contributors.
    When a Change has multiple benefits, it's better to list them all.

<!-- This does not need to be a full-fledged document. Describe the dimensions of tests that this change implementation is expected to pass when it is done.  If it needs to be tested with different hardware or software configurations, indicate them.  The more specific you can be, the better the community testing can be.
Remember that you are writing this how to for interested testers to use to check out your change implementation - documenting what you do for testing is OK, but it's much better to document what *I* can do to test your change.
A good "how to test" should answer these four questions:


0. What special hardware / data / etc. is needed (if any)?
Only try the following if you are confortable debugging an un-bootable system and have made backups!
1. How do I prepare my system to test this change? What packages
need to be installed, config files edited, etc.?
2. What specific actions do I perform to check that the change is
working like it's supposed to?
3. What are the expected results of those actions?

== User Experience ==
<!-- If this change proposal is noticeable by users, how will their experiences change as a result?


This section partially overlaps with the Benefit to Fedora section above. This section should be primarily about the User Experience, written in a way that does not assume deep technical knowledge. More detailed technical description should be left for the Benefit to Fedora section.
There should be no visible change in user experience.
 
Describe what Users will see or notice, for example:
  - Packages are compressed more efficiently, making downloads and upgrades faster by 10%.
  - Kerberos tickets can be renewed automatically. Users will now have to authenticate less and become more productive. Credential management improvements mean a user can start their work day with a single sign on and not have to pause for reauthentication during their entire day.
- Libreoffice is one of the most commonly installed applications on Fedora and it is now available by default to help users "hit the ground running".
- Green has been scientifically proven to be the most relaxing color. The move to a default background color of green with green text will result in Fedora users being the most relaxed users of any operating system.
