 3. Install [esp-open-sdk](https://github.com/pfalcon/esp-open-sdk), build it with `make toolchain esptool libhal STANDALONE=n`, then edit your PATH and add the generated toolchain bin directory. The path will be something like /path/to/esp-open-sdk/xtensa-lx106-elf/bin. (Despite the similar name esp-open-sdk has different maintainers - but we think it's fantastic!)
 
 4. Install [esptool.py](https://github.com/themadinventor/esptool) and make it available on your PATH. If you used esp-open-sdk then this is done already.
+
+From this point, you can either run the "build.sh" script that will guide you through the next steps, or otherwise just keep reading on. 
+Remember to make the script executable by running:
+```shell
+chmod -x /path/to/build.sh 
+```
 5. Checkout [esp-open-rtos](https://github.com/SuperHouse/esp-open-rtos) and set SDK_PATH environment variable pointing to it.
 6. Configure settings:
