Upload and activate the parent and child theme.
In this tutorial I will show you how to install Luanda Service.
The theme comes as a zip containing the parent theme (Luanda Service) and a child theme (Luanda Service Child). Install both and activate the child.
1. Go to Appearance > Themes, click Add New, then Upload Theme.
2. Choose the zip file and click Install Now.
3. Activate Luanda Service Child. Keep the child active: it is the safe home for custom changes, and parent updates will not overwrite them.
4. Go to Settings > Permalinks and click Save Changes once, so the team archive address works.
