Project Overview & Quickstart (piqnt/testbed) # Piqnt Runtime Piqnt Runtime is a collection of middlewares that power Piqnt.com, and Planck.js Testbed. You can use it to run your code, or mix-and-match middlewares to create your own runtime environment. ### Middleware Architecture To learn more about middlewares, check out the [Polymatic](https://github.com/piqnt/polymatic) project. ### Usage Examples To learn how you can use it in your project, see following examples: [Testbed](https://github.com/piqnt/runtime/blob/main/packages/planck-testbed/src/testbed/TestbedMain.ts) - Includes a preset of middlewares for running Planck.js physics engine examples. Pinball game ([Play](https://piqnt.github.io/polymatic-example-pinball/), [Source](https://github.com/piqnt/polymatic-example-pinball/)) - Uses a subset of Testbed middlewares, and adds custom middlewares for loading svg table design, loading data into physics, user input handing, etc. ## 2.
