-If you want to use the Espressif toolchain (esp32 or esp32c3), you can most conveniently install it with `west`:
-
-``` Bash
-cd $ZEPHYR_BASE
-west espressif install

-After that set `ESPRESSIF_TOOLCHAIN_PATH` according to the output, for example `~/.espressif/tools/zephyr`.
+The [Zephyr SDK](https://github.com/zephyrproject-rtos/sdk-ng) provides toolchains for all supported targets. Follow the instructions in the [documentation](https://docs.zephyrproject.org/latest/develop/getting_started/index.html#install-zephyr-sdk) to ensure it is installed and configured correctly.
 
 Note:
 WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](../doc/build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in Zephyr, interpreter, AOT and builtin libc are enabled by default.
