The Coaching Pro theme comes with the option to use styled text for your site title and tagline or to upload a logo image of your choice.
To use the text options, from your WordPress dashboard click on Appearance > Customize.
Open the “Site Identity” menu. Enter your site title and tagline, then click “Save.”
To use the logo option, from your WordPress dashboard click on Appearance > Customize.
Click on the “Logo Image” menu. Upload your logo file. The recommended logo size is 300px x 60px for the theme, so upload an image that is 600px × 120px to accommodate for Retina and HDPI displays.
