The toolchain will be extracted into ``~/esp/xtensa-esp32-elf/`` directory.
2. The toolchain will be extracted into ``~/esp/xtensa-esp32-elf/`` directory.
To use it, you will need to update your ``PATH`` environment variable in ``~/.bash_profile`` file. To make ``xtensa-esp32-elf`` available for all terminal sessions, add the following line to your ``~/.bash_profile`` file::

Alternatively, you may create an alias for the above command. This way you can get the toolchain only when you need it. To do this, add different line to your ``~/.bash_profile`` file::

alias get_esp32="export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin"

Then when you need the toolchain you can type ``get_esp32`` on the command line and the toolchain will be added to your ``PATH``.

3. Finally, run the following command to verify if ``PATH`` is correctly set::
printenv PATH
You are looking for similar result containing toolchain's path at the end of displayed string::
$ printenv PATH
/home/user-name/bin:/home/user-name/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/user-name/esp/xtensa-esp32-elf/bin
Instead of ``/home/user-name`` there should be a home path specific to your installation.
