 If you want to help contribute to ``trio-websocket``, then you will need to
 install additional dependencies that are used for testing and documentation. The
 following sequence of commands will clone the repository, create a virtual
-environment, and install the developer dependencies.
-
-::
+environment, and install the developer dependencies::
 
     $ git clone [email protected]:HyperionGray/trio-websocket.git
     $ cd trio-websocket
     $ python3 -m venv venv
     $ source venv/bin/activate
-    (venv) $ pip install --editable .[dev]
+    (venv) $ pip install -r requirements-dev.txt
+
+This example uses Python's built-in ``venv`` package, but you can of course use
+other virtual environment tools such as ``virtualenvwrapper``.
+
+Development Dependencies
+------------------------
+
+You may have noticed in the developer installation instructions that the project
+is installed from ``requirements-dev.txt`` and not from ``setup.py``. This
+requirements file contains extra dependencies only needed for development, such
+as PyTest, Sphinx, etc. The requirements file is generated from
+``requirements-dev.in`` using `pip-tools
+<https://pypi.org/project/pip-tools/>`__, which pins each dependency to an exact
+version. This helps developers make reproducible builds across all environments,
+including Travis CI.
+
+If you need to modify the library's dependencies or modify the dev dependencies,
+you will need to regenerate the requirements file::
+
+    $ pip-compile --output-file requirements-dev.txt setup.py requirements-dev.in
+
+The ``pip-compile`` tool can also upgrade packages, which may be useful if you
+want to update pinned versions without changing the declared dependencies in
+``setup.py`` or ``requirements-dev.in``. The following command upgrades only the
+named packages::
+
+    $ pip-compile -P package1 -P package2 requirements-dev.txt
+
+Or you can upgrade all packages::
+
+    $ pip-compile --upgrade requirements-dev.txt
+
+
+After making changes to dependencies, you should check in the file you changed
+(e.g. ``setup.py`` or ``requirements-dev.txt``) as well as the generated
+``requirements-dev.txt``.
 
+In the future, when you checkout new branches or update existing branches, you
+should use ``pip-sync`` to synchronize dependencies. This command will add,
+upgrade, and even *remove* packages in order to make your environment match the
+expected development environment.
