 ## Readme - English
 
-- coming soon -
+
+
+This firmware configuration activates many new features of the Marlin firmware:
+
+ * Mesh bed calibration
+ * S-curve acceleration
+ * "Juction Deviation" instead of the classic "Jerk"
+ * Baby stepping during printing
+ * Bilinear Bed Leveling (BBL)
+ * Manual editing of the measuring points
+ * Full Anycubic touchscreen support
+ * Pause & filament change function
+ * Automatic EEPROM initialization
+ * Filament Runout Sensor can be deactivated in the menu
+ * Power outage support
+
+What's better in coparison to other firmwares (bug fixes):
+ * Tidy special menu
+ * Printer does not freeze if you have files with special characters (umlauts, Chinese..) on your SD card
+ * No stupid "wobble" of the nozzle after stopping printing
+ * No firmware crash when there are too many files on the SD card
+ * No crash with SD cards over 16 GB
+ * Acoustic alarm in case of a thermal runaway
+ * No freezing when SD card + USB is used at the same time
+ * No freezing when you press pause and try to resume
+ * No freezing when the filament is empty
+
+Known bugs:
+ * Filament Runout Sensor is reactivated with every reboot
+ * Power outage support does not work reliably
+
+---
+
+### FAQ:
+
+> Knutwurst, why are you still doing such a firmware? Aren't there already so many?
+
+Because I've never seen one that doesn't contain the stupid bugs like the crashes when you have files with special characters on the SD card.
+
+>Why is my printer so much louder than before?
+
+Your component fan is now running at full speed, which it did no before. Simply set the speed to 70% in the slicer (e.g. Cura) and you will have the old speed again. This modification is necessary if you want to replace the fan. Many aftermarket fans do not run properly or at all with the original 8V.
+
+> Is your firmware better than others?
+
+No. But certainly not worse either.
+
+
+> Where are the downloads?
+
+Further down.
+
+
+> Do I have to turn the plugs for TMC drivers?
+
+Nope, just download the correct version.
+
+
+> Which TMC motor drivers should I buy? The V2 or the Bigtreetech V3?
+
+Neither! There is no "V2" or "V3". The official last version of Trinamic is v1.2 and the two major primary manufacturers for the real SilentStepSticks are FYSTEC and WATTERROTT. Just stay away from Bigtreetech.
+
+
+> When I installed the drivers, my mainboard gave me the "magic smoke". Is that normal?
+
+No. You installed the drivers the wrong way round. Now the Zener diode (733A) is burned. Exchange it and everything works again. You can probably throw away your wrongly inserted drivers.
+
+
+> As with other firmwares, do I still have to set the E-Steps if I have a Mega S?
+
+No, just download the correct version. Nevertheless, you should still calibrate the e-steps.

+### 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 with PlatformIO or the Arduino IDE.
+
+-> `i3_Mega.hex` is for the unmodified original Anycubic i3 MEGA (without S).
+
+-> `i3_Mega_TMC.hex` has optimizations and inverted outputs for TMC2100 and TMC2208 motor drivers.
+
+-> `i3_Mega_S.hex` is used if you use the newer "S" version with titan extruder.
+
+-> `i3_Mega_S_TMC.hex` you use if you use both the "S" version with titan extruder and TMC motor driver.
+
+
