You get an “About Me” widget that gives you the option to upload a portrait photo and to write a brief introduction of yourself.
In your admin, go to Appearance >> Widgets
Drag the Clarified About Me widget into the sidebar of your choice (I recommend the Blog, Left, or Right Sidebar). Please note that if you are using this in the blog area of your website, then you would choose the Blog Sidebar position.
Now you can fill out the information and using the image upload, you can add your portrait to the widget. If you decide to add a signature (an image-based one), you can use the other image upload setting to do that. If you want a button to link to another information source, fill in the Link URL field.
Note: The link field shows a # symbol which is only a fake link; you will want to put in a full URL into this field.
Click Save on your widget and you are done!
