Summary
Review of what you've learned
To insert a reference, first activate VisualEditor by clicking "edit" at the top of an article. Once the toolbar has appeared, click where you wish to insert the reference. Clicking the 
button will open up a dialog box that allows you to enter the details of your reference.
There are two simple ways to add the information for a reference: Fully automatic (by just inserting the web URL) or manually by filling in a template (where you add each piece of information separately).
The automatic option is the easiest. Wikipedia con often auto-format a reference citation if you just insert the website URL and click "Generate". Take a look at the citation that it then suggests. To accept it, click "Insert". You can always modify the details if it has got something wrong (e.g. the publication date), by clicking "Edit".
(Note, dates should be YYYY-MM-DD)
Sometimes the reference you want to add doesn't fall into any of these categories (for example, perhaps you wish to cite a speech). In this case, you can enter the information fully manually using the "Basic form"
