 ### Open source app dependency projects
+[pip and venv](https://docs.python.org/3/library/venv.html) are part of 
+Python 3's standard library as of version 3.3. However, there are numerous
+other open source libraries that can be helpful when managing application
+dependencies in your projects, as listed below.
+
 * [Autoenv](https://github.com/kennethreitz/autoenv) is a tool for activating
   environment variables stored in a `.env` file in your projects' home
   directories. Environment variables aren't managed by virtualenv and although
   virtualenvwrapper has some hooks for handling them, it's often easiest to
   use a shell script or `.env` file to set them in a development environment.
 
+* [Pipenv](https://pipenv.readthedocs.io/en/latest/) is a newer Python 
+  packaging and dependency management library that has seen some adoption
+  in place of the standard `pip` library.
+
 * [Pipreqs](https://github.com/bndr/pipreqs) searches through a project for
   dependencies based on imports. It then generates a `requirements.txt` file
   based on the libraries necessary to run those dependencies. Note though that
