I would enjoy reading it and learning about what you do. You can look thru the Hubpages help section about how to write a Hub.
Or you can write it on your computer and then cut and paste in to the hub format.
go to "start a new hub" at the top right of your page once you are logged into hubpages and start there. The one thing that got me was the number 2. where it asks you to make a unique webaddress for your hub. It will do that automatically from your title. If it doesn't - the the title you have chosen has been taken already so just change the title.
I look forward to reading your work.
