Annotating PDF Documents

There are two ways to edit PDFs.

Kami is a great chrome extension:

https://chrome.google.com/webstore/detail/kami-extension-pdf-and-do/ecnphlgnajanjnkcmbpancdjoidceilk?hl=en

Or ReadWrite PDF Viewer which is available to all students:

https://chrome.google.com/webstore/detail/texthelp-pdf-reader/feepmdlmhplaojabeoecaobfmibooaid?hl=en-GB

Both allow you to annotate PDF documents.
