+## ADB location resolution
+
+By default the extension is looking for ADB in the following locations:
+- Linux - `$HOME/Android/Sdk`
+- MacOS - `$HOME/Library/Android/sdk/platform-tools`
+- Windows - `%USERPROFILE%\AppData\Local\Android\Sdk\platform-tools` (if the `%USERPROFILE%` environment variable is not defined the path to the profile directory of the current user will be used as the starting point)
+
+The extension will resolve the ADB location each time an ADB command is executed.
+
+The ADB location can be customized using the `Setup custom ADB location` command. The custom ADB location can be cleared using  the `Remove custom ADB location` command.
