* [TASK] Remove copy&paste left over

This change removes a copy&paste left over
from the `Quickstart/Index.rst`.

* [TASK] Modify quickguide prerequisites page

This change modifies the `Quickstart/1-Prerequisites.rst`
to add minor additional information to some points.

* [TASK] Enhance `Quickstart/Git setup guide`

This change modifes the `Quickguide/3-Git.rst` file
to enhance the experience by ...

* ensuring single commands per code block to allow block
  copy and pasting by using the block copy icon.
* using more cross operating-system compatible commands.
* note when in a command replacements are needed
* add a general tip to copy commands to a text file or
  editor to do the replacement before pasting it into a
  terminal
* add a additional verification step at the end.

* [TASK] Enhance `Quickguide: Set up DDEV` page

This change modifies `Quickstart/4-DDEV.rst` to
enhance the guide slightly.

* [TASK] Enhance `Quick Start: Set up TYPO3` chapter

This change modifies the `Quickstart/5-TYPO3.rst` file
to enhance the experience for the user proceeding this
chapter by

* ensuring to have single command or command chain to
  simply use the copy icon and have no issues pasting
  them into the terminal.
* adding generic project folder switch as note at the
  top.
* providing `EXT:styleguide` create commands creating
  the frontend based on `TypoScript records` instead
  of the Site Sets feature, which seems to be broken
  for now with ddev.
* Reworded the attention block to state the reason
  instead of leaving a to do - which looks kind of
  weired for readers.

* [TASK] Minor change of quickstart patch intermezzo

* [TASK] Enhance `Quick Start: Create a patch` chapter

This change modifies the `Create a patch` chapter
slightly to make it more easier for contributors
to create their first patch by

* ensuring single commands or proper command chains
  which can be properly copied using the copy icon
  and pasted into a terminal.
* using `:caption:` tags for `code blocks` to explain
  each command copy block itself.
* adding general remember on top to be in the right
  folder.
* adding a additional `cleanup` point at the end
  providing suitable commands and small explanation.

* [TASK] Hint for clean repository to the `patch intermezzo` chapter

This change adds a general hint to the
`Quick Start: Create a patch - Intention`
chapter raising awareness for a clean
repository state and how to deal with it
if not.

* [TASK] Sync `repository reset and cleanup` information in multiple places

This change streamlines the `reset and cleanup` steps and
information throughout multiple places to contain as much
information as possible while still beeing able to copy
single command and chains for easy copy&paste experiance.

* [TASK] Combined code review

This addresses:

* Rename "15 minutes" to "under 30 minutes"
* Streamline $HOME dir usage
* Remove some explanations that enlarge the text too much
* Remove some of the prerequisites that are needed,
  and would otherwise take up too much text. The long version
  is still part of this guide, it fits there better.
* streamline ddev config for rename
* fix minor typos

* [TASK] Use same convention homefolder for git setup like mentioned in other places

* [TASK] Move `attention` block to `EXT:styleguide` point

* [TASK] Use `git commit -a` instead of the not wildy known `git commit .`

+Quick Start: Prerequisites
+==========================
+
+We will not explain you how to set up the following prerequisites.
+There are several tutorials for this on the web, and if you follow
+the Quick Start guide, you should know how to do this.
+
+..  rst-class:: bignums-xxl
+
+1.  Operating System
+
+    A computer running Windows with WSL2, macOS or Linux - connected to
+    the Internet.
+
+2.  Docker
+
+    Either the "original" `Docker Desktop <https://www.docker.com/products/docker-desktop/>`__
+    or an alternative like `OrbStack <https://orbstack.dev/>`__, `Podman <https://podman.io/>`__,
+    `Colima <https://github.com/abiosoft/colima>`__ or others. Linux users
+    do not need to install any `Desktop` variants, but can use their base
+    Docker or Podman setup.
+
+3.  DDEV
+
+    `DDEV <https://ddev.com>`__ is a layer on top of Docker. How to utilize it is
+    covered in this guide.
+
+4.  Terminal (Bash)
+
+    Your operating system needs to provide a Bash terminal, many steps of this guide
+    will be executed on the shell.
+
+    You are free to use another local shell for your work, but the scripts
+    provided by the TYPO3 Core (most importantly `runTests.sh`) require Bash
+    to be available.
+
+5.  Git client
+
+    This guide expects you can execute `git` terminal commands.
+
+    This guide uses the *https* method to connect to GitHub, so you do not
+    need to have a GitHub account.
+
+6.  SSH client plus SSH key(s) and an email account
+
+    This guide expects you can execute `ssh` terminal commands and connect to
+    foreign hosts. You will need a private SSH key pair and know how to authenticate
+    with it. You need an email account to setup accounts.
+
+7.  PHP IDE / Editor
+
+    It is recommended to use a good PHP IDE. As part of the target audience of this guide
+    you should already use something like PhpStorm, Visual Studio Code, vi(m)...
+
+..  _quickstart-assumptions:
+8.  Assumed path structure and name usage
+
+    We will use:
+
+    * **$HOME/work/TYPO3-Contribute/** as your working directory (created in the guide).
+    * **John Doe** to be your name.
+    * **[email protected]** to be your email address that you used for all accounts.
+    * **john-doe** to be your TYPO3.org username.
+    * A TYPO3 **legacy mode** installation (Non-Composer) with MariaDB 10.11 and PHP 8.2.
+
+    Adjust any occurences of this to match your environment.

+============================
+
+
+
+..  rst-class:: bignums-xxl
+
+1.  My TYPO3 (`https://my.typo3.org`__)
+
+    Vital account! Acts as a Single Sign On (SSO) provider for
+    several other services. See :ref:`TYPO3Account`.
+
+2.  Gerrit (`https://review.typo3.org`__)
+
+    The code review system that is used for your code contributions.
+    There, all patches are commented and voted/approved/rejected.
+
+    First login via the `My TYPO3` SSO account. Afterwards you need to upload
+    your SSH public key here. See :ref:`GerritAccount`.
+
+3.  Forge (`https://forge.typo3.org/`__)
+
+    The issue tracking platform (Redmine) where bugs and feature
+    requests are reported. Every patch in Gerrit needs to have
+    a corresponding issue.
+
+    You login here via the `My TYPO3` SSO account.
+
+4.  Slack (`https://typo3.slack.com/`__)
+
+    The chat platform where developers get in touch with each other.
+    The channel `#typo3-cms-coredev` is important.
+
+    You need to register an account for Slack, see `https://typo3.org/community/meet/chat-slack/`__
+    and :ref:`slack-account`.
