Models are generators that know how to create certains types of components. Models use input provided by you, as a web developer, to configure the generated code to your exact needs. Models allow developers to inherit the skills of the PHP experts who coded the model.
GenHelm ships with over 70 models which we describe below. The supplied models are generally sufficient to create most websites. Nevertheless, one of the most powerful features of GenHelm is that it is fully extensible. This means that if you have a need to create a certain class of component for which there is no supplied model, you can easily create a new model designed to satisfy your exact requirements.
In the sections below we describe various groups of models and provide links to the pages that describe these models in detail.

Many models are used to build different types of content pages. Your goal when using GenHelm should be to choose the page-oriented model that best aligns with the type of page you want to build. For example, if you are building an Frequently Asked Questions page, you will want to use the FAQ model since this model was developed for this exact purpose. In other cases, you may not find a model that is an exact match so you will use one of the general-purpose page-oriented models. Follow this link to learn about all of the page-oriented models that are available.
Several models are used to define and render images, galleries and widgets associated with images. Visit this link to learn about image handling in GenHelm.
