+Combining multiple Manifest trees (informational)
+-------------------------------------------------
+
+This specification permits nesting multiple hierarchical Manifest trees.
+In this layout, the specific directories of the Manifest tree can
+be verified both as a part of another top-level Manifest,
+and as an independent Manifest tree (when obtained without the parent
+directory).
+
+For this to work, the sub-Manifest file in the directory must also
+satisfy the requirements for the top-level Manifest file. That is:
+
+- it must be named ``Manifest`` and not compressed,
+
+- it must cover all the files in this directory and its subdirectories
+  (i.e. no files from the directory tree can be covered by parent
+  Manifest),
+
+- if authenticity verification is desired, it must be OpenPGP-signed.
+
+It should be noted that if such a directory is a subdirectory of a valid
+Manifest tree, the sub-Manifest needs to be valid according
+to the top-level Manifest and the OpenPGP signature is disregarded
+as detailed in `Manifest file locations and nesting`_. The top-level
+behavior is exhibited only when the directory is obtained without parent
+directories.
