+h2(#requirements). Compute image requirements
+
+Arvados comes with a build script to automate the creation of a suitable compute node image (see "The build script":#building below). It is provided as a convenience. It is also possible to create a compoute node image via other means. These are the requirements:
+
+* for AWS: the ssh public key for @arvados-dispatch-cloud@ (the one that corresponds with @Containers/DispatchPrivateKey@ in the Arvados config file) needs to go into ~/.ssh/authorized_keys for the ssh user you want @arvados-dispatch-cloud@ to use (cf. @CloudVMs/DriverParameters/AdminUsername@ in the Arvados config file) and that user needs to be able to sudo without password prompt, unless you use `root` in which case sudo is not used.
+* for Azure: @arvados-dispatch-cloud@ automatically extracts the ssh public key from the value of @Containers/DispatchPrivateKey@ and uses an API call to create the user specified in @CloudVMs/DriverParameters/AdminUsername@ with that ssh public key and password-less sudo enabled.
+* SSH needs to be running and reachable by @arvados-dispatch-cloud@ on port 22 (or a custom port, see @CloudVMS/SSHPort@ to in the Arvados config file)
+* the @python3-arvados-fuse@ package needs to be installed
+* @Docker@ or @Singularity@ needs to be installed and running (cf. @Containers/RuntimeEngine@ in the Arvados config file).
+* all available scratch space should be made available under `/tmp`.
