 **NOTE: This is the "dev" (development) branch of the Addon Manager. Most users should use "main" instead.**
 
-Install and update third-party addons to FreeCAD, including Workbenches, Macros, Preference Packs, and more. FreeCAD
-ships with a point-in-time snapshot of this Addon: by the time you install FreeCAD it is possible that version of the
-Addon Manager is no longer the most recent version. Install *this* addon to update the internal Addon Manager to the
-latest version (and to allow future self-updating).

 ## Addon Sources
 
-The main source of addons is the git repository at https://github.com/FreeCAD/FreeCAD-Addons. Custom addon sources can
-be configured in the Addon Manager preferences when running FreeCAD. These addons are primarily written by
-third parties and provided by repositories not under the FreeCAD authors' or maintainers' control: you use these addons
-at your own risk.

 ## Information for Addon Developers
 
-To submit an addon you have created see the documentation [here](https://github.com/FreeCAD/FreeCAD-addons/blob/master/Documentation/Submission.md).
-For information about developing an addon in the first place, see [the FreeCAD wiki](https://wiki.freecad.org/Workbench_creation#Distribution).
-The Addon Manager supports five different types of addons: "Workbench", "Macro", "Preference Pack", "Bundle", and "Other". This
-information is provided to the Addon Manager via a file called `package.xml` whose [format is documented on the wiki](https://wiki.freecad.org/Package_Metadata).

-The Addon Manager relies on a remote cache of all addons maintained at https://addons.freecad.org,
-[generated by a script](https://github.com/FreeCAD/AddonManager/blob/main/AddonCatalogCacheCreator.py) that runs
-every six hours. This cache contains the complete code for all addons listed in the addon catalog. Another
-process runs to cache all macros from both [the GitHub repository](https://github.com/FreeCAD/FreeCAD-macros/)
-and [the Wiki](https://wiki.freecad.org/Macros_recipes). All official catalog-based addons and macros are downloaded from
-that server.

 ## Addon Manager Design Goals
 
-The Addon Manager is now designed to be self-updating, with a goal of allowing versions of FreeCAD back to 0.21 to
-use their default copy of Addon Manager to install a new version of Addon Manager. This means that the Addon Manager
-should support PySide2 and Python 3.8 for the foreseeable future.
+The Addon Manager is now designed to be self-updating, with a goal of allowing versions of FreeCAD back to 0.21 to use their default copy of Addon Manager to install a new version of Addon Manager. A special backwards-compatibility branch is available for versions of FreeCAD still running on Qt5 and/or Python 3.8, but the main development of the Addon Manager now requires Qt6 and Python 3.11.
 
-The Addon Manager is also designed to be run in a "standalone" mode to allow for easier UI development. In this mode
-it does not interact with FreeCAD at all, and does not use or affect "real" FreeCAD preferences, module installation,
-etc.

 ### Request to Developers
 
-If you plan on submitting a PR to improve the Addon Manager, please write unit tests as appropriate for your development
-work. Network and filesystem access should be mocked, and the tests should be able to run without access to FreeCAD (always
-use the `addonmanager_freecad_interface.py` file to mediate FreeCAD interactions).

 ## Roadmap
 
-This module is under active development, with the following rough plan (the order of priorities is only approximate,
-and actual development may happen out of order).
-
-1. Handle download interruption and allow resumption
-2. Automatic update check for Addon Manager to update itself, even if it's not installed as an Addon
-3. Implement automatic Python dependency resolution on FreeCAD/Python version switching
-4. Construct `requirements.txt` for <depends> to ensure correct Python module installation
-5. FreeCAD in Virtual Env to eliminate `--user` option to `pip`
-6. Add/remove macro toolbar button
-7. Add option to perform background update checks and recaches
-8. Implement "offline mode" for uninstallation
-9. Add option to run Preference Pack after install
-10. Redesign the GUI
-
-Bug reports and pull requests are welcome. Please make sure you are familiar with
-[the contributing process](https://github.com/FreeCAD/FreeCAD/blob/main/CONTRIBUTING.md).
