Now that our files are downloaded, we are ready to install them into WordPress. Navigate to your site’s login page and login. Typically, you can go to http://yoursite.com/wp-login.php (remember to replace “yoursite.com” with your site’s actual url)
You can upload Cornerstone starting at Appearance > Themes and clicking “Add New” and then again “Upload Theme” (both of these buttons appear at the top of the screen). Drag and drop the “cornerstone.zip” file here or choose the file by clicking “Choose File” and then once located Click “Install Now”.
After WordPress does the heavy lifting of installing, simply click “Activate”.
Once activated, you’ll see a notice for recommended plugins. We will cover these in-depth later but for right now we need to install the WP for Church Sidekick which you should have downloaded earlier.
