+### Data used
+
+- 25 GiB random file
+- 25 GiB empty file
+- 1024 1 KiB random files
+- 1024 1 KiB empty files
+- Linux kernel source (compressed and non-compressed)
+- 100 million-sided regular polygon, generated by the `headless-deterministic` branch of [confused_ace_noises/maths-demos](https://git.askiiart.net/confused_ace_noises/maths-demos)
+
+## Usage
+
+You can put the data in folders in `./data/mountpoints/`, which can be on different filesystems (including stuff like [DwarFS](https://github.com/mhx/dwarfs) archives mounted with FUSE). Running `grab-data` and `prep-dirs` will create all the necessary files it can, at which point you just add the polygon data, put the stuff to be benchmarked in the `mountpoints` dir, then run it with the `benchmark` argument.
