Hello,
Thanks for the Purchase.
Since this is a Static HTML5/CSS3 Template, the changes are required to be done manually in the HTML/CSS/JS Files as these are pre-designed Templates that are provided with the Package and can be modified based on user requirements and their Website's content.
You can consider generating a Custom Package here: http://docs.semicolonweb.com/docs/getting-started/installation/ according to the HTML Files you need for your website and our Package Generator will sort the Files for you to download. Suppose, you need the demo-seo.html Template, simply choose this File in the Package Generator and then press the Generate button. A Custom Package will be generated for you only based on your selected file.
You can simply edit those HTML Files manually (pre-existing knowledge of HTML/CSS is required) according to your needs in a Text Editor like Sublime Text/VS Code and then upload it to your Servers using FTP. We recommend starting with a Localhost Setup on your personal PC/Macbook before you deploy using FTP.
HTML5/CSS3 Templates contain Codes that are self-explanatory and (as we have mentioned) pre-existing knowledge of HTML/CSS is required to Edit the Templates. The Documentations already includes all the Basic and some more required setup details on How to Edit/Customize the Templates and since HTML/CSS are generic languages, Documentations and Video Tutorials on these setups are not included. More Documentations on Logos can be found here: https://docs.semicolonweb.com/docs/getting-started/logo-settings/ . To change the Logo, you will need to change the Images (png):
