+### Gyro Alignment Settings
+
+Gyro alignment configuration is mutual exclusive.
+
+Default we use #define `USE_GYRO_1_ALIGN` `ALIGNMENT`
+
+where `ALIGNMENT` preset is one of
+```bash
+CW0_DEG
+CW90_DEG
+CW180_DEG
+CW270_DEG
+CW0_DEG_FLIP
+CW90_DEG_FLIP
+CW180_DEG_FLIP
+CW270_DEG_FLIP
+ALIGN_CUSTOM
+```
+
+When using `ALIGN_CUSTOM` specify orientation in `DECIDEGREES` ranging from -3600-3600:
+
+```
+#define ALIGN_1_GYRO_ROLL DECIDEGREES
+#define ALIGN_1_GYRO_PITCH DECIDEGREES
+#define ALIGN_1_GYRO_ROLL DECIDEGREES
+```

 ### Serial Receiver Provider
 
 BNF boards may want to configure the serial receiver provider on the flight controller. Example:
