1 - Extract the files in the zip you downloaded from the zip.
2 - Log in to the Perfect panel admin panel, then follow the steps > appearance > themes > theme you want to edit > edit code.
3 - We went to the editing area by choosing the theme you want to edit and saying edit code.

Then let's open the twig files and other files in the file you extracted from the zip with notepad.

Replace the codes of the theme you selected in your admin panel with the codes you downloaded and save it.

eg;

If the layout.twig is extracted from the zip, the layout.twig part in the admin panel theme editing area will be completely deleted and the codes in the unzipped layout.twig will be pasted and saved. This will be done for all files.
