Installing Projectopia is as simple as uploading the plugin to your WordPress website. Firstly though, you’ll need to obtain the files from CodeCanyon.
Now that you have your zip file, you need to extract the main plugin file from within the zip. Unzip the file and you will be left with a folder containing readme.txt and projectopia.zip
Log in to your WordPress website and go to Plugins -> Add New -> Upload Plugin. Browse for the projectopia.zip file that you downloaded and click Install Now.
