Question about sharing with Google Docs

I have recently started to use Google Docs with the intent of using it to easily Share content I create. I have problems with the process that trying online help didn't fix.
I want to set up a document so that I can make a link to it that allows anybody with the link access to view the document. I would rather avoid having to add people to the permissions list manually. Every link I make according to the online help's instructions leads to an access denied page.
I know what I want to do is possible, as I frequent many other people's documents with alink, and I'm sure they have never heard of me to add a permission. I would prefer the process used with the Google Docs iOS app, but I'll take any tips that get the job done in an accessible manner.
Thanks in advance.
