qgis - Create a hyperlink to a pdf file in the attribute table

I want to add a hyperlink to a pdf file into the attribute table of a vector layer. I already read the documentation about evis and the answered questions about this here. It didn't seem difficult, but I still can't create a hyperlink...can someone give me a short step by step information about this? Unfortunately I have no access to youtube...

I'm using Qgis (2.0.1) and evis is a plugin that should allow to create such hyperlinks via a event browser. I first added a column "Link" to the attribute table and put the link to the document in this column. this is the link to the documentation for evis: http://www.qgis.org/en/docs/user_manual/plugins/plugins_evis.html#figure-evis-2

Thanks a lot! G.H.
