-README for the verdin-mx8mp Relax
-============================
-
-  The directory provides board support for the Toradex Verdin mx8mp.
-  Note: this port works on the internal Cortex-M7 auxiliary core, NOT the main Cortex-53 complex!
-
-  LEDs and buttons shall be connected to header pins like this:
-  - LED21 on GPIO_4
-  - LED22 on GPIO_3
-  - LED23 on GPIO_2
-  - LED24 on GPIO_1
-  - SW11 on GPIO_5_CSI
-  You can adjust this pinout in verdin_mx8mp.h
-
-Status
-======
-
-  2023-08-23:   The Verdin mx8mp boots into NSH, provides the NSH prompt.
-  2023-09-04:   gpio support, i2c support (tested with on-board ina219 sensor)

+verdin-mx8mp
+=============
+
+This directory provides board support for the Toradex Verdin i.MX8MP. This
+port runs on the internal Cortex-M7 auxiliary core, not on the main
+Cortex-A53 complex.
+
+GPIO Connections
+================
+
+Connect LEDs and buttons to the header pins as follows:
+
+* ``LED21`` on ``GPIO_4``
+* ``LED22`` on ``GPIO_3``
+* ``LED23`` on ``GPIO_2``
+* ``LED24`` on ``GPIO_1``
+* ``SW11`` on ``GPIO_5_CSI``
+
+You can adjust this pin mapping in ``verdin_mx8mp.h``.

+Status
+======
+
+* 2023-08-23: boots into NSH and provides the NSH prompt
+* 2023-09-04: GPIO and I2C support work, including the on-board INA219 sensor
