 ## STM32 core sources files location
 
-By installing the stm32 core thanks the [[Boards Manager|Getting-Started#About-Boards-manager-concept]], the extracted package is located here:
+The install directory of Arduino IDE can be found here:
+
+* `/home/\<USERNAME>/.arduino15/` _(Linux)_
+* `/Users/\<USERNAME>/Library/Arduino15/` _(Mac)_
+* `C:\Users\<USERNAME>\AppData\Local\Arduino15\` _(Windows 10 and 11)_
 
-Go to the local Arduino directory.<br>
-> [!TIP]
-> The location is displayed in the "**Preferences**" dialog.
+First make sure you have installed the stm32 core using the
+[[Arduino Boards Manager|Getting-Started#About-Boards-manager-concept]].
 
-It should be:
+The stm32 core files can then be found in this directory:
 
-* `/home/\<USERNAME\>/.arduino15/` _(Linux)_
-* `/Users/\<USERNAME\>/Library/Arduino15/` _(Mac)_
-* `c:\Users\\<USERNAME\>\AppData\Local\Arduino15\` _(Windows 10, Windows 7)_
-* `c:\Users\\<USERNAME\>\AppData\Roaming\Arduino15\` _(Windows Vista)_
-* `c:\Documents and Settings\\<USERNAME\>\Application Data\Arduino15\` _(Windows XP)_
+`<Arduino IDE install directory>/packages/STMicroelectronics/hardware/stm32/2.8.1`.
 
-Then, go to "**_\<local Arduino directory\>/packages/STMicroelectronics/hardware/stm32/_**" directory.<br>
-Directory named with the STM32 Core version installed is present. Example: 2.0.0
+The `2.8.1` changes depending on your installed stm32 core version.
 
-If you use the portable IDE as described [here](https://www.arduino.cc/en/Guide/PortableIDE) then the location is in your Arduino install directory:
+If you use the portable IDE, as described [here](https://www.arduino.cc/en/Guide/PortableIDE),
+then the location is here instead:
 
-* `\<Arduino IDE install path\>/portable/` _(Linux/Mac)_
-* `\<Arduino IDE install path\>\portable\` _(Windows)_
+* `<Arduino IDE install directory>/portable/` _(Linux/Mac)_
+* `<Arduino IDE install directory>\portable\` _(Windows 10 and 11)_
 
 ## STM32 Tools files location
 
-Go to the local Arduino directory. See above.<br>
-Then, go to "**_\<local Arduino directory\>/packages/STMicroelectronics/tools/STM32Tools/_**" directory.<br>
-Directory named with the STM32 Tools version installed is present. Example: 1.4.0
+Go to the Arduino IDE install directory. See above.
 
+Then, go to the `<Arduino install directory>/packages/STMicroelectronics/tools/STM32Tools/2.2.3` directory.
 
+The `2.2.3` changes depending on your installed stm32 tools version.
