A method performed in a web-based environment on a computer system teaches a user to implement an application. The method includes providing predetermined applications and presenting an annotation page that includes one or more annotations descriptive of a predetermined application. Each annotation includes keyword links, annotation links, and detail of implementation of the application. The method includes permitting the user to select a link in an annotation. If the user selects a keyword link, reference documentation associated with that keyword is presented. If the user selects an annotation link, another annotation descriptive of another source file of a predetermined application is presented.
