 This project aims to uphold Python [community norms](https://www.python.org/psf/conduct/) and make use of [recommended
 tooling](https://packaging.python.org/guides/tool-recommendations/).
 
+To get started, you'll want to:
+- clone the repo into a project directory
+- setup a virtual 3.5+ python environment in the project directory
+- activate that virtual environment
+- install the dependencies
+- validate your build environment with some sample commands
+
+While there are several different tools and techniques you can use to accomplish the
+steps listed above, the following is an example which uses `venv`.
+
+```bash
+# Clone the repo
+cd ~/dev
+git clone https://github.com/rstudio/rsconnect-python.git
+cd rsconnect-python
+# Setup a virtual python environment
+python3 -m venv .venv
+# Activate the virtual environment
+source .venv/bin/activate
+# install our requirements into the virtual environment
+pip install -r requirements.txt
+# install rsconnect-python with a symbolic link to the locations repository, 
+# meaning any changes to code in there will automatically be reflected
+pip install -e ./
+```
+
 ## Workflow
 
-The [`test` job in the default GitHub Actions workflow](.github/workflows/main.yml) reflects a typical set of steps for
-building and testing.
+With your venv setup and active, as described previously, running rsconnect-python using your codebase is as simple as running the `rsconnect` command from the terminal.
+
+Typical makefile targets are:
+
+```bash
+# verify code formats are correct
+make fmt
+# lint the codebase
+make lint
+# run the tests (w/ python 3.8)
+make test
+# run the tests with all versions of python
+make all-tests
+```
+
+As another example, the [`test` job in the default GitHub Actions workflow](.github/workflows/main.yml) 
+uses some of these targets during the CI for building and testing.
