At startup, kitty detects if the shell you have configured (either system wide
or in kitty.conf) is a supported shell. If so, kitty injects some shell specific
code into the shell, to enable shell integration. How it does so varies for
different shells.
.. tab:: bash/zsh
.. tab:: zsh
For these shells, kitty adds a couple of lines to
the bottom of the shell's rc files (in an atomic manner) to load the shell
integration code.
For zsh, kitty sets the ``ZDOTDIR`` environment variable to make zsh load
kitty's :file:`.zshenv` which in turn loads the shell integration code then
restores the original value of ``ZDOTDIR`` and finally sources the original
:file:`.zshenv`. The remainder of zsh's startup process proceeds as normal.
