Google docs being probably the most popular service for managing online documents, I am going to show you how with no flash or PDF browser plug-ins you can embed Google Docs, spreadsheets, documents, forms and presentations into your Joomla website and this works for Joomla 2.5 up to 3.0 and beyond.
Step 1: Setting up your documents
Before you start you have to make sure that your documents are labeled as public and not private otherwise this will not work. Open the document that you want to share and click the Share link that the top of the browser to make it public readable.
