+# Live Stream API Python Samples
+
+This directory contains samples for the Live Stream API. Use this API to
+transcode live, linear video streams into a variety of formats. The Live Stream
+API benefits broadcasters, production companies, businesses, and individuals
+looking to transform their live video content for use across a variety of user
+devices. For more information, see the
+[Live Stream API documentation](https://cloud.google.com/livestream/).
+
+## Setup
+
+To run the samples, you need to first follow the steps in
+[Before you begin](https://cloud.google.com/livestream/docs/how-to/before-you-begin).
+
+For more information on authentication, refer to the
+[Authentication Getting Started Guide](https://cloud.google.com/docs/authentication/getting-started).
+
+## Install Dependencies
+
+1. Clone python-video-live-stream and change directories to the sample directory
+you want to use.
+
+        $ git clone https://github.com/googleapis/python-video-live-stream.git
+
+1. Install [pip](https://pip.pypa.io/) and
+[virtualenv](https://virtualenv.pypa.io/) if you do not already have them. You
+may want to refer to the
+[Python Development Environment Setup Guide](https://cloud.google.com/python/setup)
+for Google Cloud Platform for instructions.
+
+1. Create a virtualenv. Samples are compatible with Python 3.6+.
+
+        $ virtualenv env
+        $ source env/bin/activate
+
+1. Install the dependencies needed to run the samples.
+
+        $ pip install -r requirements.txt
+
+## Testing
+
+Make sure to enable the Live Stream API on the test project. Set the following
+environment variable:
+
+*   `GOOGLE_CLOUD_PROJECT`
