+
+These configurations activate many of the new advanced features of the Marlin firmware:
+
+ * Auto Calibration
+ * Auto Bed Leveling
+ * Pause & Filament Change
+
+**Important**: Before doing anything else after updating the firmware, go to  
+`Configuration > Advanced Settings > Initialize EEPROM` to get rid of old configurations
+
+After that you should connect the Z-Probe and start `Configuration > Delta Calibration > Auto Calibration`. When it's done don't forget to also do `Configuration > Delta Calibration > Store Settings` to make it permanent.
+
+You should also do a `Motion > Bed Leveling > Level bed` followed by `Store Settings` to ensure a perfect leveling.
+
+Please do a manual paper test (moving the nozzle slowly down to Z0 and checking with a piece of paper) - if it's not perfect, use `Configuration > Advanced Settings > Probe Z Offset` to correct the difference and execute the calibration again.
+
+**Also Important**: if you value your Z-Probe do NOT execute `Configuration > Delta Configuration > Probe Z-offset` - this can destroy the Z-Probe, see issue [#11337](https://github.com/MarlinFirmware/Marlin/issues/11337)

+# Selection of firmware version
+
+Please select the correct subdirectory for your printer.
+
+The Kossel comes in 3 versions:
+
+ * Pulley
+ * Linear
+ * Linear Plus
+
+ Pulley and Linear use the same configuration, the Linear Plus is bigger and uses slightly different configurations.
+
+The probe attachment is also available in different versions:
+Typically the probes for the Anycubic Delta Kossel printers come in two different versions:
+
+  * Version 1: Z Height of -19.0mm
