Navigate to your WordPress Dashboard and click on Appearance > Themes.
Now click on the Add New button on top of the page and then click Upload Theme.
Choose the Paris.zip file from the MadridTheme-CM.zip file you downloaded. Please make sure to unzip the zip file first when you download it. The zip file you need to upload is Paris.zip (zipped within the ParisTheme-CM.zip).
Important! Don’t upload the whole ParisTheme-CM.zip folder! If you get a ‘Theme is missing the style.css stylesheet’ error you have probably uploaded the wrong folder.
Click on Install Now and once it is installed, click the Activate button. Congrats! You successfully installed your new Design.
