+### Feature Request
+Please put [FR] in the issue title: `[FR] Add-on that goes 'ping'`
+
+------------------------------------------------------------
+### Compile Error
+When I compile with `FEATURE_X` I get an error:
+```
+Paste_the_error_text_here
+```

+### Bug Report
+- Description: ---
+- Expected behaviour: ---
+- Actual behaviour: ---
+- Steps to reproduce:
+  - Do this
+  - Do that
+
+Attach a ZIP of `Configuration.h` and `Configuration_adv.h` by dropping here.
+
+------------------------------------------------------------
+### Bug Report Tips
+- When troubleshooting, use `M502` followed by `M500` to reset EEPROM to defaults.
+- Use `DEBUG_LEVELING_FEATURE` with `M111 S247` for detailed logging of homing/leveling.
+- Format text with: **bold**, _italic_, `code`.
+- Format C++ with three backticks, plus "cpp":
+```cpp
+void my_function(bool do_it) {
+  // Hold this spot
+}
+```

+ *   #define MAX7219_LOAD_PIN  79

+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))

- * Thermal Protection protects your printer from damage and fire if a
- * thermistor falls out or temperature sensors fail in any way.
+ * Thermal Protection provides additional protection to your printer from damage
+ * and fire. Marlin always includes safe min and max temperature ranges which
+ * protect against a broken or disconnected thermistor wire.
  *
- * The issue: If a thermistor falls out or a temperature sensor fails,
- * Marlin can no longer sense the actual temperature. Since a disconnected
- * thermistor reads as a low temperature, the firmware will keep the heater on.
+ * The issue: If a thermistor falls out, it will report the much lower
+ * temperature of the air in the room, and the the firmware will keep
+ * the heater on.
  *
  * The solution: Once the temperature reaches the target, start observing.
- * If the temperature stays too far below the target (hysteresis) for too long (period),
- * the firmware will halt the machine as a safety precaution.
+ * If the temperature stays too far below the target (hysteresis) for too

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:
+ *
+ *    Y                     Z                     Z

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:
+ *
+ *    Y                     Z                     Z

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:

- * If the temperature stays too far below the target (hysteresis) for too long (period),
