 ASDF Unit Schemas
 **********************
 
-The ASDF Unit Schemas define a set of schemas for serializing the units defined by
-:ref:`astropy.units <astropy:astropy-units>` for the ASDF file format. These schemas
-are based upon the schemas in the :ref:`ASDF Standard <asdf-standard:asdf-standard>` and
-are packaged for use by the :ref:`ASDF <asdf:asdf>` library.
-
-.. note::
-   This is only a schema package, to use these schemas to serialize astropy units,
-   one must install the :ref:`asdf-astropy <asdf-astropy:asdf-astropy>` package.
-
-Included Resources
-==================
-
-The following are listings of all the schemas provided by this package for ASDF.
-
-.. note::
-  Typically, schemas are used in ASDF via their tag, which can be found in the manifest.
-  Using a transform in ASDF it is recommended that you use the tag instead of a direct
-  reference to the schema. When doing so make sure you are using the correct manifest version.
