First things first. You will need an image of yourself. The image may be png or jpg, and must be square. Size is less important, but aim for a sensible resolution. Nothing pixellated or an unnecessarily high resolution.
The author pictures should be placed in
Author info is added as a section in the YAML file
Copy the example block and then customise:
Dave Placeholder: name : Dave Placeholder bio : Goat Herder.<br/>Cheese, goats cheese, other types of cheese, mostly cheese avatar : images/authors/dave.jpg email : firstname.lastname@example.org twitter : Coffee_Dad github : monsieurfromage linkedin : daveplaceholder links: - label: "Blogsite" icon : "fas fa-fw fa-link" url : "http://monsieurfromageblog.com"
Indentation is important with YAML.
Note that you can incorporate multiple website links. Just repeat the three lines and customise. The icon uses the free Font Awesome 5 set if you want to use something other than the link icon. Only link to blog sites particular to the author, rather than general company sites.
