+
+This is a guide for those who want to learn more about Infix using a
+hands-on approach.  You need a Linux 🐧 system with Qemu installed, we
+recommend [Debian][] based systems, like [Ubuntu][] and [Linux Mint][].
+
+> For a pain-free experience we recommend enabling CPU virtualization in
+> your BIOS/UEFI, which for many computers is disabled by default.
+
+From this point we assume you have your x86_64/AMD64 based Linux system
+up and running.  Time to start your favorite terminal application! 😃
+
+
+### Installing Qemu
+
+```bash
+$ sudo apt install qemu-system-x86 virt-manager
+```
+
+### Download Infix
+
+Go to https://github.com/kernelkit/infix/releases/latest and scroll down
+to *Assets*.  Download the tarball named `infix-x86_64-VERSION.tar.gz`,
+where VERSION is the year+month+patch release number.
+
+It extracts to a subdirectory:
+
+
+```bash
+$ sudo apt install qemu-system-x86 virt-manager
+```
+
+
+### Running Infix
+
+> Depending on how you have [set up your Linux][sudo] installation, the
+> following may require being run with superuser privileges, i.e., you
+> may need to prepend the command with `sudo`.
+
+For more Ethernet ports in your emulated system you need to change the
+Qemu configuration used for Infix.  This can be done using a menuconfig
+interface, which requires the following extra package:
+
+```bash
+$ sudo apt install kconfig-frontends
+```
+
+We can now enter the configuration:
+
+```bash
+$ ./qemu.sh -c
+```
+
+Go down to *Networking*, select *TAP*, now you can change the *Number of
+TAPs*, e.g. to 10.  Exit and save the configuration, then you can start
+Qemu again:
+
+   ./qemu.sh
+
+> Make sure to do a factory reset from the CLI, otherwise you will be
+> stuck with that single interface from before.
