-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::
+
+ export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
+
+ 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``.

- export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
+ printenv PATH

+ You are looking for similar result containing toolchain's path at the end of displayed string::
- alias get_esp32="export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin"
+ $ 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
-Then when you need the toolchain you can type ``get_esp32`` on the command line and the toolchain will be added to your ``PATH``.
+ Instead of ``/home/user-name`` there should be a home path specific to your installation.
