-By default, hiSHtory is installed in `~/.hishtory/`. If you want to customize this, you can do so by setting the `HISHTORY_PATH` environment variable to a path relative to your home directory (e.g. `export HISHTORY_PATH=.config/hishtory`). This must be set both when you install hiSHtory and when you use hiSHtory, so it is recommend to set it in your `.bashrc`/`.zshrc`/`.fishrc` before installing hiSHtory.
