+# Transcoder API Python Samples
+
+This directory contains samples for the Transcoder API. Use this API to transcode videos into a variety of formats. The Transcoder API benefits broadcasters, production companies, businesses, and individuals looking to transform their video content for use across a variety of user devices. For more information, see the [Transcoder API documentation](https://cloud.google.com/transcoder/).
+
+## Setup
+
+To run the samples, you need to first follow the steps in [Before you begin](https://cloud.google.com/transcoder/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-docs-samples and change directory to the sample directory you want to use.
+
+        $ git clone https://github.com/googleapis/python-video-transcoder.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
+
+## The client library
+
+This sample uses the [Google Cloud Client Library for Python](https://googlecloudplatform.github.io/google-cloud-python/).
+You can read the documentation for more details on API usage and use GitHub
+to [browse the source](https://github.com/GoogleCloudPlatform/google-cloud-python) and [report issues](https://github.com/GoogleCloudPlatform/google-cloud-python/issues).
+
+## Testing
+
+Make sure to enable the Transcoder API on the test project. Set the following environment variables:
+
+*   `GOOGLE_CLOUD_PROJECT`
+*   `GOOGLE_CLOUD_PROJECT_NUMBER`
