Abstract: Methods and systems, including computer program products, implementing techniques for generating documentation for a product. The techniques include receiving a set of feature descriptions for a product, receiving a document template, receiving user data about a first user and different user data about a second user, and receiving mapping information that maps user data values to product features; then, for each user, using the mapping information and the respective user data to identify product features that are of interest to the user, and generating documentation for the product specific to the user, including reading the document template, and for each feature description referred to in the document template, adding the feature description to the documentation if the feature description describes one of the product features identified as being of interest to the user, otherwise, not adding the feature description to the documentation.
