-##### Reformatting wolfSSL as a compatible Arduino Library
-This is a shell script that will re-organize the wolfSSL library to be 
-compatible with Arduino projects that use Arduino IDE 1.5.0 or newer. 
-The Arduino IDE requires a library's source files to be in the library's root 
-directory with a header file in the name of the library. This script moves all 
-src/ files to the `IDE/ARDUINO/wolfSSL/src` directory and creates a stub header
-file called `wolfssl.h` inside that directory.
+Many of the supported boards are natively built-in to the [Arduino IDE Board Manager](https://docs.arduino.cc/software/ide-v2/tutorials/ide-v2-board-manager/)
+and by adding [additional cores](https://docs.arduino.cc/learn/starting-guide/cores/) as needed.
 
-Step 1: To configure wolfSSL with Arduino, enter the following from within the
-wolfssl/IDE/ARDUINO directory:
+STM32 Support can be added by including this link in the "Additional Boards Managers URLs" field
+from [stm32duino/Arduino_Core_STM32](https://github.com/stm32duino/Arduino_Core_STM32?tab=readme-ov-file#getting-started)   .
 
-        `./wolfssl-arduino.sh`
+```
+https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json
+```
 
-Step 2: Copy the directory wolfSSL that was just created to:
-`~/Documents/Arduino/libraries/` directory so the Arduino IDE can find it.
+## Using wolfSSL from the Arduino IDE
 
-Step 3: Edit `<arduino-libraries>/wolfSSL/src/user_settings.h`
+Coming soon! https://github.com/wolfSSL/arduino-wolfSSL See [PR #1](https://github.com/wolfSSL/Arduino-wolfSSL/pull/1).
+
+This option will allow wolfSSL to be installed directly using the native Arduino tools.
+
+## Manually Reformatting wolfSSL as a Compatible Arduino Library
+
+Use [this](./wolfssl-arduino.sh) shell script that will re-organize the wolfSSL library to be 
+compatible with [Arduino Library Specification](https://arduino.github.io/arduino-cli/0.35/library-specification/)
+for projects that use Arduino IDE 1.5.0 or newer.
+
+The Arduino IDE requires a library's source files to be in the library's root directory with a
+header file in the name of the library. This script moves all `src/` files to the `IDE/ARDUINO/wolfSSL/src`
+directory and creates a stub header file called `wolfssl.h` inside that directory.
+
+### Step 1:
+
+To configure wolfSSL with Arduino, enter one of the following commands
+from within the `wolfssl/IDE/ARDUINO` directory:
+
+1. `./wolfssl-arduino.sh`
+    - Creates an Arduino Library directory structure in the local `wolfSSL` directory of `IDE/ARDUINO`.
+    - You can add your own `user_settings.h`, or copy/rename the [default](../../examples/configs/user_settings_arduino.h).
+
+2. `./wolfssl-arduino.sh INSTALL` (The most common option)
+    - Creates an Arduino Library in the local `wolfSSL` directory
+    - Moves that directory to the Arduino library directory:
+        - `$HOME/Arduino/libraries` for most bash environments
+        - `/mnt/c/Users/$USER/Documents/Arduino/libraries` (for WSL)
+    - Adds the [default](../../examples/configs/user_settings_arduino.h) as `user_settings.h`.
+    - The wolfSSL library is now available from the Arduino IDE.
+
+3. `./wolfssl-arduino.sh INSTALL /path/to/repository` (Used to update [arduino-wolfSSL](https://github.com/wolfSSL/arduino-wolfSSL))
+    - Creates an Arduino Library in `wolfSSL` directory
+    - Copies that directory contents to the specified `/path/to/repository`
+    - Adds the [default](../../examples/configs/user_settings_arduino.h) as `user_settings.h`. 
+
+4. `./wolfssl-arduino.sh INSTALL /path/to/any/other/directory`
+    - Creates an Arduino Library in `wolfSSL` directory
+    - Copies that directory contents to the specified `/path/to/any/other/directory`
+
+### Step 2:
+
+Edit `<arduino-libraries>/wolfSSL/src/user_settings.h`
 If building for Intel Galileo platform add: `#define INTEL_GALILEO`.
-Add any other custom settings, for a good start see the examples in wolfssl root
-"/examples/configs/user_settings_*.h"
+Add any other custom settings. For a good start see the examples in wolfssl root
+"[/examples/configs/user_settings_*.h](https://github.com/wolfssl/wolfssl/tree/master/examples/configs)"
+
+### Step 3:
 
-Step 4: If you experience any issues with custom user_settings.h see the wolfssl
