+## Dependencies of hook libraries
+Pumptool's hook libraries aim for having no dependencies other than what is already required by the
+different games to run.
+
+However, there are some exceptions that require additional libraries in order to allow the following
+features to work correctly:
+* Hook libraries, e.g. `nx2hook` that support network features, e.g. usb profiles with pumpnet
+* IO API implementations that support real devices, e.g. real PIUIO, which use libusb-1.0

+Taken from [the Dockerfile for building pumptools](../../Dockerfile), the following commands install
+the dependencies that you need on an Ubuntu-based system:

+```bash
+dpkg --add-architecture i386
+apt-get update && apt-get install -y \
