+swtpm (TPM emulation)
+
+swtpm emulates a TPM (Trusted Process Module) in software; once
+running, QEMU can attach TPMs to virtual machines (to run Windows 11,
+for example). See specs/tpm.rst in the QEMU doc directory for more
+details.
+
+Please note that the swtpm command will emulate TPM 1.2 unless it is
+called with "--tpm2".
+
+For more information about the different tools provided by swtpm, see
+the documents in /usr/doc/swtpm-0.8.2/readmes.
+
+The user and group for TSS are both "tss" by default, and should have
+been created before compiling the trousers package.
+
+It is not possible to install Windows 11 to a virtual machine without
+Secure Boot-enabled UEFI firmware and variables. See edk2-ovmf on SBo.
