+## Two Trees BlueR Configurations
+
+This folder contains default configurations for the Two Trees BlueR.
+
+Three different configurations are provided, suitable for the different BlueR release versions:
+
+- `BlueR V1` : First version of BlueR with a metal extruder.
+- `BlueR V2` : (Formerly "BlueR" out of the box.) BMG extruder with Blue parts and integrated endstop for X and Z.
+- `BlueR V3` : (Formerly "BlueR V2" out of the box.) BMG extruder and more Black parts as your predecessor.
+
+Extra options are provided for BlueR stepper driver variants:
+
+- Enable `BLUER_TMC2209` if your board has TMC2209 drivers.
+- Enable `BLUER_INVERTED_E` for the BlueR V2 if the E motor goes in reverse.
+- Enable `BLUER_BLTOUCH` if you want to enable BLTOUCH. (BLTOUCH Will Replace Z_Min_Plug)

+## Two Trees Sapphire Configurations
+
+This folder contains two default configurations for the Two Trees Sapphire Plus V2. The V2 has Dual Z Axis limit switches, and the V2.1 has a single Z limit switch, as well as a different board.
+
+## Supported Versions
+
+|Version|Board|Z-axis switches|
+|---|---|---|
+| V2|MKS Robin Nano V1.2|2|
+| V2.1| MKS Robin Nano V1.3|1|
+
+Make sure you always test the endstops/limit switches after using this configuration, as newer printers may have slight electrical and mechanical differences.
+
+#### Configuration differences on V2.1
+
+- Build with BOARD_MKS_ROBIN_NANO_V1_3_F4;
+- Disable ZMAX plug (Z increments lower the bed);
+- Enable INVERT_Z_DIR (Z increments lower the bed);
+- Disable PRINTCOUNTER (not supported with current settings);
+- Rotate TFT 180º;
+- Enable endstops always on;
+- Disable multiple Z endstops;
+
+## Available options
+
+By default the standard Marlin Touch UI will be used. Enable the `SAPPHIRE_PLUS_MKS_UI` option for the MKS UI.
+
+Enable the `SAPPHIRE_PLUS_BLTOUCH` option for BLTouch support.
+
+Enable the `SAPPHIRE_PLUS_TMC_UART` option for TMC UART support for the X, Y and E steppers. Note: you will need some hardware modification skills to modify the stepper sticks. A solder pad needs to be bridged to connect PDN to USART pin. Then a 1K resistor and wire is needed to connect the USART pin to the appropriate spare pin on MKS Robin Nano V1.2 board.
