-    "In Devito, an `Operator` carries out three fundamental tasks: generation of low-level code, JIT compilation, and execution. Overall, the lowering process performed by an `Operator` – from high-level equations to dynamically compiled and executable code – consists of multiple compiler passes, summarized in the Figure bellow. The following series of notebooks will describe these compilation passes in a hands-on fashion. We will explore the heart of the `Operator` class, which orchestrates code generation and compilation. For more details, see the [Operator class](https://github.com/devitocodes/devito/blob/master/devito/operator.py).\n",
