+# Pipenv Example
+
+## Overview
+This example demonstrates how to build a Python Pipenv project with Artifactory, while collecting build-info.
+
+## Before Running the Example
+### Set Up the Environment 
+1. Make sure **Python** is installed and the **python** command is in your PATH.
+2. Install **pipenv**. You can use the [Pip Documentation](https://pipenv.pypa.io/en/latest/) and also [Installing packages using pip and virtual environments](https://realpython.com/pipenv-guide/)
+3. Create three Pypi repositories in Artifactory - a local, remote and a virtual repository. You can use the [PyPi Repositories Documentation](https://www.jfrog.com/confluence/display/RTF/PyPI+Repositories).
+* The remote repository should proxy *https://files.pythonhosted.org* (the default when creating a Pypi remote repository). 
+* Name the virtual repository *pipy*.
+* The virtual repository should include the remote repository.
+* The virtual repository should have the local repository set as the *Default Deployment Repository*.
+4. Make sure **wheel** and **setuptools** are installed. You can use the [Installing Packages Documentation](https://packaging.python.org/tutorials/installing-packages/).
+5. Make sure version 1.28.0 or above of [JFrog CLI](https://jfrog.com/getcli/) is installed.
+
+### Validate the Setup
+In your terminal, validate that the following commands work.
+```console
+Output Python version:
+> python --version
+
+Output pipenv version:
+> pipenv --version
+
+Output JFrog CLI version:
+> jfrog --version
+```
+
+## Running the Example
+CD to the root project directory
+
+```console
+Configure Artifactory:
+> jfrog c add
+
+Configure the project's resolution repository. You shoud set the virtual repository you created.
+> jfrog pipec
+
+Install project dependencies with pip from Artifactory:
+> jfrog pipenv install --build-name=my-pipenv-build --build-number=1 --module=jfrog-pipenv-example
+
+Package the project, create distribution archives (tar.gz and whl):
+> python setup.py sdist bdist_wheel
+
+Upload the packages to the pypi repository in Artifactory:
+> jfrog rt u dist/ pypi/ --build-name=my-pipenv-build --build-number=1 --module=jfrog-pipenv-example
+
+Collect environment variables and add them to the build info:
+> jfrog rt bce my-pipenv-build 1
+
+Publish the build info to Artifactory:
+> jfrog rt bp my-pipenv-build 1
+
+Install published package by installing it from Artifactory using pip:
+> jfrog pipenv-install jfrog-pipenv-example
