The amount of French I know could fit inside a thimble and still have room left over and yet I use the website all the time. Many of the words have similar English spellings and/or meanings. It also helps that you know in what context the words are used that is census, vital records and navigating the website. For instance "Retour" means return. "Imprimer" means print. For what you cannot figure out use a French/English dictionary. I have a hard-copy, but there are tons of websites and even Google will translate words. For that matter Google will translate any typed words on the page for you. Once you get the hang of it, it is easy.
If you're not sure what a link does try it and find out. The worst that can happen is you start over or have to go back.
