 - presence of Docker on the build machine to run the build process, the guest OS needs to be able to mount host directories for Docker (i.e. on Linux, SELinux permissions might be needed).
 - presence on the target deploy server (i.e., at the machine designated at TESTFQDN) of a properly deployed [LetsEncrypt server certificate](https://letsencrypt.org/getting-started).
+- (optional) presence of a root CA certificate and key in `rootca/CA.crt` and `rootca/CA.key`, respectively. If the directory `rootca` is not present on the build machine, a new root CA will be generated by the build script.
 
 By default, the server is built to a specific set of versions of `liboqs`, `openssl`, `oqs-provider` and `nginx`. These versions are encoded in `build-ubuntu.sh` and may be changed/upgraded there.
