-# Additional files
-
-This folder contains additional files that are used in the project.
-
-## `generate_configs.py`
-
-The script is used to generate configuration files for a benchmark setup
-consisting of a device under testing (DUT) and automatic test equipment (ATE),
-basically a strong machine capable of running multiple Rosenpass instances at
-once.
-
-At the top of the script multiple variables can be set to configure the DUT IP
-address and more. Once configured you may run `python3 generate_configs.py` to
-create the configuration files.
-
-A new folder called `output/` is created containing the subfolder `dut/` and
-`ate/`. The former has to be copied on the DUT, ideally reproducible hardware
-like a Raspberry Pi, while the latter is copied to the ATE, i.e. a laptop.
-
-### Running a benchmark
-
-On the ATE a run script is required since multiple instances of `rosenpass` are
-started with different configurations in parallel. The scripts are named after
-the number of instances they start, e.g. `run-50.sh` starts 50 instances.
-
-```shell
-# on the ATE aka laptop
-cd output/ate
-./run-10.sh
-```
-
-On the DUT you start a single Rosenpass instance with the configuration matching
-the ATE number of peers.
-
-```shell
-# on the DUT aka Raspberry Pi
-rosenpass exchange-config configs/dut-10.toml
-```
-
-Use whatever measurement tool you like to monitor the DUT and ATE.
