 instance, in the example above the first execution of `trixi_include` takes about
 20 seconds, while subsequent runs require less than 60 *milli*seconds.
 
+### Showcase of advanced features
+The presentation [From Mesh Generation to Adaptive Simulation: A Journey in Julia](https://youtu.be/_N4ozHr-t9E),
+originally given as part of JuliaCon 2022, outlines how to use Trixi for an adaptive simulation
+of the compressible Euler equations in two spatial dimensions on a complex domain. More details
+as well as code to run the simulation presented can be found at the
+[reproducibility repository](https://github.com/trixi-framework/talk-2022-juliacon_toolchain)
