To change your logo start by going to the customizer menu. The customizer menu is where all of your websites settings live and let you quickly and easily customize your website to match your church's brand.
Step 1. Go to the customizer menu and click on General Settings > Site Identity.
Step 2. Make sure to keep the "hide site title" and "hide site tagline" checked as to keep the minimal design on your website header.
Click "change logo" and add your own logo in. The default size for the logo is 250 pixels by 50 pixel.
To change the retina size logo, follow the same steps for the main logo but double the size. The default size for the retina logo is 500 pixels by 100 pixels.
After adding both logos make sure to click the green "publish" button to save your changes.
