Open your site.
Then click on Upload Files.

Then upload your file. The file name will work
better if you don’t use a long one like this:
The Evidence for the Ressurection--
McDowell.pdf
I would change this to something like: resurrection.pdf
Then upload it.
Then go to your Site-Weaver and create or
select the page you want to put the link on.
Click on add link.
Select area you want to put the link in and
click on the Add Here button.
Then enter the name of the link like the below
example:

Also click on the Link Url: Browser… and
select any file in that directory. This is to get the path to the
.pdf file for you. Then where I circled the insert1.shtml above.
(because this is the file I choose.) replace that file name with the
file name you uploaded. I uploaded resurection.pdf.
Click done.
And the link is there and people can click on
the link and read the file.
