How to set up signature on my posts

I have yet to set up my posts so that my signature, i.e. my company logo information, shows up on my posts. or would I have to always type or insert it each posts? Can anyone help?

Thanks.

Click on quick links above and click edit signature. Add your info and your done.

Upper left: control pane,
then, settings and options,
then, edit signature…

Thanks. This is a test post to see if signature shows up.

Looks great well done
