1. Unzip the downloaded theme and throw it into the wordpress folder /wp-content/themes/, and then go to your wordpress backstage to find the theme to enable.

2. "Appearance" in wordpress background > "Themes", see the interface of uploading and installing themes on the right, and then find the theme to upload and install on your own computer and enable Sanlian.

The rest is to try to use this template slowly. If you have any questions, you can exchange notes with Viasys. If you don't understand, we can study together and make progress together.
