+Managing Published Scala Dependencies
+=====================================
+
+In preparation for Chisel 3.5, in Chipyard 1.5 Chisel, FIRRTL, the FIRRTL
+interpreter, and Treadle, were transitioned from being built-from-source to
+managed as published dependencies. Their submodules have been removed.
+Switching between published versions can be achieved by changing the versions
+specified in Chipyard's ``build.sbt``.
+
+Lists of available artifacts can be using search.maven.org or mvnrepository.org:
+
+- `Chisel3 <https://mvnrepository.com/artifact/edu.berkeley.cs/chisel3>`_
+- `FIRRTL <https://mvnrepository.com/artifact/edu.berkeley.cs/firrtl>`_
+- `FIRRTL Interpreter <https://mvnrepository.com/artifact/edu.berkeley.cs/firrtl-interpreter>`_
+- `Treadle <https://mvnrepository.com/artifact/edu.berkeley.cs/treadle>`_
+
+
+Publishing Local Changes
+-------------------------
+
+Under the new system, the simplest means to make custom source modifications to the packages
+above is to run ``sbt +publishLocal`` from within a locally modified clone of each
+of their respective repositories. This will post your custom variant
+to your local ivy2 repository, which can generally be found at ``~/.ivy2``.  See the `SBT
+documentation <https://www.scala-sbt.org/1.x/docs/Publishing.html#Publishing+locally>`_
+for more detail.
+
+In practice, this will require the following steps:
+
+#. Check out and modify the desired projects.
+#. Take note of, or modify, the versions of each projects (in
+   their ``build.sbt``). If you're cloning from ``master`` generally
+   these will have default versions of ``1.X-SNAPSHOT``, where ``X`` is
+   not-yet-released next major version. You can modify the version string, to say ``1.X-<MYSUFFIX>``, to uniquely identify your
+   change.
+#. Call ``sbt +publishLocal`` in each subproject. You may need to rebuild other
+   published dependencies. SBT will be clear about what it is publishing and
+   where it is putting it. The ``+`` is generally necessary and ensures that
+   all cross versions of the package are published.
+#. Update the Chisel or FIRRTL version in Chipyard's ``build.sbt`` to match the
+   versions of your locally published packages.
+#. Use Chipyard as you would normally. Now when you call out to make in
+   Chipyard you should see SBT resolving dependencies to the locally
+   published instances in your local ivy2 repository.
+#. When you're finished, consider removing your locally published packages (by
+   removing the appropriate directory in your ivy2 repository) to prevent
+   accidentally reusing them in the future.
+
+A final word of caution: packages you publish to your local ivy repository will
+be visible to other projects you may be building on your system. For example,
+if you locally publish Chisel 3.5.0, other projects that depend on Chisel 3.5.0
+will preferentially use the locally published variant over the version
+available on Maven (the "real" 3.5.0).  Take care to note versions you are
+publishing and remove locally published versions once you are done with them.
