-## 3. History
-
-- 1996-10-01: Carsten Sørensen (a.k.a. SurfSmurf) releases
-  [xAsm](http://otakunozoku.com/RGBDSdocs/asm.htm),
-  [xLink](http://otakunozoku.com/RGBDSdocs/link.htm), and
-  [RGBFix](http://otakunozoku.com/RGBDSdocs/fix.htm),
-  a Game Boy SM83 (GBZ80) assembler/linker system for DOS/Win32.
-- 1997-07-03: Sørensen releases [ASMotor](http://otakunozoku.com/RGBDSdocs/geninfo.htm),
-  packaging the three programs together and moving towards making them a
-  general-purpose target-independent system.
-- 1999-08-01: Justin Lloyd (a.k.a. Otaku no Zoku) adapts ASMotor to re-focus
-  on SM83 assembly/machine code, and releases this version as
-  [RGBDS](http://otakunozoku.com/rednex-gameboy-development-system/).
-- 2009-06-11: Vegard Nossum adapts the code to be more UNIX-like and releases
-  this version as [rgbds-linux](https://github.com/vegard/rgbds-linux).
-- 2010-01-12: Anthony J. Bentley [forks](https://github.com/bentley) Nossum's
-  repository. The fork becomes the reference implementation of RGBDS.
-- 2010-09-25: Sørensen continues development of
-  [ASMotor](https://github.com/asmotor/asmotor) to this day.
-- 2015-01-18: stag019 begins implementing [RGBGFX](https://github.com/stag019/rgbgfx),
-  a PNG-to-Game Boy graphics converter, for eventual integration into RGBDS.
-- 2016-09-05: RGBGFX is
-  [integrated](https://github.com/gbdev/rgbds/commit/c3c31138ddbd8680d4e67957e387f2816798a71b)
-  into Bentley's repository.
-- 2017-02-23: Bentley's repository is moved to the [rednex](https://github.com/rednex)
-  organization.
-- 2018-01-26: The codebase is [relicensed](https://github.com/gbdev/rgbds/issues/128)
-  under the MIT license.
-- 2020-09-15: The repository is [moved](https://github.com/gbdev/rgbds/issues/567)
-  to the [gbdev](https://github.com/gbdev) organization.
-- 2022-05-17: The [rgbds.gbdev.io](https://rgbds.gbdev.io) website for RGBDS
-  documentation and downloads is published.
