-          Please redo this PR starting with the `bugfix-2.0.x` branch and be careful to target `bugfix-2.0.x` when resubmitting the PR.

-          It may help to set your fork's default branch to `bugfix-2.0.x`.

+ *
+ * Algorithm & Implementation: Scott Mudge - mail@scottmudge.com
+ * Date: Dec. 2020
+ *
+ * Specifically optimized for 3D printing G-Code, this is a zero-cost data compression method
+ * which packs ~180-190% more data into the same amount of bytes going to the CNC controller.
+ * As a majority of G-Code can be represented by a restricted alphabet, I performed histogram
+ * analysis on a wide variety of 3D printing gcode samples, and found ~93% of all gcode could
+ * be represented by the same 15-character alphabet.
+ *
+ * This allowed me to design a system of packing 2 8-bit characters into a single byte, assuming
+ * they fall within this limited 15-character alphabet. Using a 4-bit lookup table, these 8-bit
+ * characters can be represented by a 4-bit index.
+ *
+ * Combined with some logic to allow commingling of full-width characters outside of this 15-
+ * character alphabet (at the cost of an extra 8-bits per full-width character), and by stripping
+ * out unnecessary comments, the end result is gcode which is roughly half the original size.
+ *
+ * Why did I do this? I noticed micro-stuttering and other data-bottleneck issues while printing
+ * objects with high curvature, especially at high speeds. There is also the issue of the limited
+ * baud rate provided by Prusa's Atmega2560-based boards, over the USB serial connection. So soft-
+ * ware like OctoPrint would also suffer this same micro-stuttering and poor print quality issue.

-# Downloads
-
-Du kannst die fertigen Binärdateien hier herunterladen: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/releases. Natürlich kannst du die Firmware mit PlatformIO auch [selbst kompilieren](https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/wiki/Howto:-Compile-Firmware-with-PlatformIO).
-
-Um es übersichtlich zu gestalten, beinhalten die Dateinamen die einzelnen Features.
-
-`_1G` steht für die erste Generation des i3 Mega mit nur einem Z Endstop. Diese Firmware ist nicht für den normalen i3 Mega geeignet!
-
-`_S` steht für den Mega S mit dem Titan Extruder.
-
-`_P` steht für den Mega P mit dem BMG Extruder.
-
-`_X` steht für den Mega X.
-
-`_TMC` steht für Trinamic TMC Motortreiber. Hierbei wird auch die Drehrichtung der Motoren invertiert.
-
-`_DGUS` steht für das "neue" blau/gelbe DGUS II Display, welches sonst kein Special-Menü anzeigen kann.
-
-`_BLT` steht für die BL-Touch Version mit Autoleveling-Sensor. Das manuelle Mesh-Leveling ist hier deaktiviert.
-
-`_10` steht für das Trigorilla_14 v1.0 Mainboard, welches normalerweise der Standard sein sollte.
-
-`_11` steht für das Trigorilla_14 v1.1 Mainboard, bei welchem sich die Pinbelegung für den Server-Port geändert hat.
-
-
-Für (fast) jede Kombination gibt es eine passende Firmware im Download-Bereich. ;)

-# Download
-
-You can download the precompiled binary files from here: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/releases. Of course you can also [compile the firmware yourself](https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/wiki/Howto:-Compile-Firmware-with-PlatformIO) with PlatformIO.
-
-In order to make it clear, the file names contain the individual features.
-
-`_1G` stands for the firt generation i3 Mega with only one Z endstop. Do NOT use this Firmware on the regular i3 Mega!
-
-`_S` stands for the Mega S with the titan extruder.
-
-`_P` stands for the Mega P with the BMG extruder.
-
-`_X` stands for the Mega X.
-
-`_TMC` stands for Trinamic TMC motor driver. The direction of rotation of the motors is also inverted.
-
-`_DGUS` stands for the "new" blue / yellow DGUS II display, which otherwise cannot show a special menu.
-
-`_BLT` stands for the BL-Touch version with auto-leveling sensor. Manual mesh leveling is deactivated here.
-
-`_10` stands for the Trigorilla_14 v1.0 mainboard, which should normally be the standard.
-
-`_11` stands for the Trigorilla_14 v1.1 mainboard, on which the pin assignment for the server port has changed.
-
-
-For (almost) every combination there is a suitable firmware in the download area. ;)
