+Pkgbase
+=======
+
+Pkgbase is the new method for managing the base system on a FreeBSD host
+or jail. It is considered experimental for 15.0-RELEASE, but will be
+made the default for version 16.0-RELEASE and above.
+
+Bootstrap
+---------
+
+To bootstrap a release using pkgbase, run ``bastille bootstrap --pkgbase RELEASE``.
+For version 14, it is not supported. For version 15 it is optional, but
+for version 16 and above, it is the default method of bootstrapping a release.
+
+Update
+------
+
+To update a release created with pkgbase, simply run ``bastille update RELEASE`` as
+you would with legacy releases.
+
+To update a thick jail, run ``bastille update TARGET`` as you would with legacy
+releases. 
+
+To update a thin jail, you must update the release that it is based on.
+
+Upgrade
+-------
+
+Upgrading is not supported for releases. See ``bastille bootstrap RELEASE`` to
+bootstrap the required release.
+
+Upgrading is supported for both thin and thick jails. Thin jails will have their
+mount points adjusted, and you will need to run ``bastille etcupdate`` on them
+when upgrading from a major release to a newer major release. For example,
+15.0-RELEASE to 16.0-RELEASE.
+
+Converting to Pkgbase
+---------------------
+
+Thick jails that are running legacy releases will have to be converted to pkgbase
+before attempting to upgrade to 16.0-RELEASE. This can be done in two ways.
+
+1. Enter the jail, fetch the ``pkgbasify`` script, and run it.
+
+.. code-block:: shell
+
+     fetch https://github.com/FreeBSDFoundation/pkgbasify/raw/refs/heads/main/pkgbasify.lua
+     chmod +x pkgbasify.lua
+     ./pkgbasify.lua
+
+2. Fetch the ``pkgbasify`` script and run it from the host using ``--rootdir``.
+
+.. code-block:: shell
+
+     fetch https://github.com/FreeBSDFoundation/pkgbasify/raw/refs/heads/main/pkgbasify.lua
+     chmod +x pkgbasify.lua
+     ./pkgbasify.lua --rootdir /usr/local/bastille/jails/TARGET/root
+
+Converting a release to pkgbase can be done the same way, but we recommend simply destroying
+and re-bootstrapping it using pkgbase. This will not work if you are running thin jails
+based on the release in question. In such a case, follow step 2 above.
