+## MSG Style Guide
+
+### ---- For Discussion and Comment Only ---
+
+Grbl has a standard for [non queried feedback](https://github.com/gnea/grbl/wiki/Grbl-v1.1-Interface#message-summary). It uses the use a [MSG: xxxx] format. Senders can do what they want with these messages, but must be able to deal with or ignore any that are in this format.
+
+### Grbl ESP32
+
+Grbl_ESP32 uses a lot of MSGs to show the setup and at key events. It may not be of use to senders but, it is crucial for effective support. 
+
+### Style Guide
+
+While anything in the [MSG:xxxxx] format should be fine, to make messages as clear and consistent as possible use this style guide.
+
+### Problem
+
+Here are the current messages in a typical startup. Note the mix of styles.
+

+**Capitalization inconsistency**

+[MSG:Axis count 3]
+```
+
+**Parameter listing method inconsistency**
+
+```
+[MSG:X  Axis Standard Stepper Step:I2SO(2) Dir:I2SO(1) Disable:I2SO(0) Limits(0.000,300.000)]
+[MSG:Macro Pin 0 GPIO(2)]
+[MSG:X  Axis limit switch on pin GPIO(33)]
+```
+
+**Punctuation Inconsistency**
+
+```
+[MSG:X  Axis Standard Stepper Step:I2SO(2) Dir:I2SO(1) Disable:I2SO(0) Limits(0.000,300.000)]
+[MSG:Laser spindle on Pin:GPIO(15), Enbl:GPIO(12), Freq:5000Hz, Res:13bits Laser mode:On]
+```
+
+### Initial Thoughts.
+
+I think the stepper MSG is one of the clearest.
+
+```
+[MSG:X  Axis Standard Stepper Step:I2SO(2) Dir:I2SO(1) Disable:I2SO(0) Limits(0.000,300.000)]
+```
+
+That could  change 
+
+```
+[MSG:X  Axis limit switch on pin GPIO(33)]
+to
+[MSG:X  Limit Switch:GPIO(33)]
+
+[MSG:Macro Pin 0 GPIO(2)]
+to
+[MSG:0 Macro Pin:GPIO(2)]
+
+[MSG:User Digital Output:0 on Pin:I2SO(24)]
+to
+[MSG:0 User Digital Output:I2SO(24)]
+
+[MSG:Axis count 3]
+to
+[MSG:Axis Count:3]
+```
+
+That makes the capitalization format a  leading uppercase character on each word.
