- [pandoc-fignos](https://github.com/tomduck/pandoc-fignos): Numbers figures and figure references.
The images section will walk you through how to add and reference images so that the pandoc system can properly number them. For example, this [figure](./ch0_1_images.md#fig:ch0_1_images-1) illustrates a VOD curve for a packaged watergel explosive and this [figure](./ch0_1_images.md#fig:ch0_1_images-2) depicts a circular arc.
## [Equations](./ch0_2_equations.md#sec:ch0_2_equations-1)
The equations section will discuss how to use equations and reference them properly. See the [internal energy equation](./ch0_2_equations.md#eq:ch0_2_equations-1) or the [detonation pressure](./ch0_2_equations.md#eq:ch0_2_equations-2)
