 The AM32 firmware is designed for STM32 ARM processors to control a brushless motor (BLDC).
-The firmware is intended to be safe and fast with smooth fast startups and linear throttle. It is meant for use with multirotor aircraft and a flight controller. The firmware can also be built with support for crawlers.

 ## Features
 
 AM32 has the following features:
 
-- Firmware upgradable via betaflight passthrough - only support G4, F4 and F7 FCs, and make sure your betaflight firmware is up to date when you trying to use passthrough
+- Firmware upgradable via betaflight passthrough, single wire serial or arduino
 - Servo PWM, Dshot(300, 600) motor protocol support
 - Bi-directional Dshot
 - KISS standard ESC telemetry
 - Variable PWM frequency
 - Sinusoidal startup mode, which is designed to get larger motors up to speed
+## Build instructions
+-"make" - builds all targets
+-"make AM32_XXX_F051 builds" a speciic target
+-Github actions
+-Fork project and run the build action within github itself.
 
 ## Firmware Release & Configuration Tool
 
@@ -29,27 +34,58 @@ To configure AM32 and upload firmware you can use the Multi_ESC config tool usin
 
 Alternately you can use the [Online-ESC Configurator](https://esc-configurator.com/) to flash or change settings with any web browser that supports web serial.

 ## Hardware
-Target compatibility List can be found [here](https://github.com/AlkaMotors/AM32-MultiRotor-ESC-firmware/wiki/List-of-Supported-Hardware) (DEC 2020)
+AM32 currently has support for STSPIN32F0, STM32F051, STM32G071, GD32E230, AT32F415 and AT32F421.
+The CKS32F051 is not recommended due to too many random issues.

-## Installation & Documentation
+## Installation & Bootloader
 
-To use AM32 firmware on a blank ESC, a bootloader must first be installed using a ST-LINK. Choose the bootloader that matches the signal input pin of the ESC.
+To use AM32 firmware on a blank ESC, a bootloader must first be installed using an ST-LINK, GD-LINK , CMIS-DAP or AT-LINK.  THe bootloader will be dependant on the MCU used ont he esc . Choose the bootloader that matches the MCU type and signal input pin of the ESC.
 The compatibility chart has the bootloader pinouts listed.
-Current bootloaders can be found [here](https://github.com/AlkaMotors/AM32_Bootloader_F051/releases/tag/V6).
+Current bootloaders can be found [here](https://github.com/AlkaMotors/AM32_Bootloader_F051/tree/main/Bootloaders).
 
+After the bootloader has been installed the main firmware from can be installed either with the configuration tools and a Betaflight flight controller or a direct connection with a usb serial adapter modified for one wire.
+
+To update an existing AM32 bootloader an update tool can be found [here](https://github.com/AlkaMotors/F051_Bootloader_Updater/releases).
