+==== Build the SDK ====
+To build the SDK for an image, append ''-c populate_sdk'' to the bitbake build command.
+For example, to build the SDK for the **ntb-dev-image** run ''bitbake ntb-dev-image -c populate_sdk''. The built SDK is located at **<myWorkspace>/build/deploy/sdk/**.
+For more information check the [[ https://developer.toradex.com/knowledge-base/linux-sdks | Linux SDKs page]] on the Toradex knowledge base.

-For example, to build the SDK for the NTB dev image ''ntb-dev-image'' run ''bitbake ntb-dev-image -c populate_sdk''
+==== Install the SDK ====
+The SDK is installed by executing the shell script in the **sdk** folder. If it should be installed on a different computer, the whole **sdk** folder must be copied over and the script executed on the target computer.
-For more information check the [[ https://developer.toradex.com/knowledge-base/linux-sdks | Toradex guide ]].
+The shell script is asking for the location to install the SDK. The default is suitable for the most of the use cases.
-===== Extensible SDK =====
+Once it is installed, the installation folder (for example **/opt/tdx-x11/2.6.4/**) contains another shell script with name **environment-setup-<xyz>**. This script can be sourced so all needed path variables are set on the current shell session. This means the script sets all variables so a following ''make'' execution will use the compiler and libraries of the SDK. The script is sourced by the point operator (there must be a space following the point!) as shown by the example below.
+<code>
+. /opt/tdx-x11/2.6.4/environment-setup-armv7at2hf-neon-tdx-linux-gnueabi
