-This is the official [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [Pipenv](http://docs.pipenv.org/en/latest/), [pip](https://pip.pypa.io/) and other excellent software.
+This is the official [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [Pipenv](http://docs.pipenv.org/), [pip](https://pip.pypa.io/) and other excellent software.
 
 Recommended web frameworks include **Django** and **Flask**. The recommended webserver is **Gunicorn**. There are no restrictions around what software can be used (as long as it's pip-installable). Web processes must bind to `$PORT`, and only the HTTP protocol is permitted for incoming connections.
 
-Some Python packages with obscure C dependencies are [not compatible](https://devcenter.heroku.com/articles/python-c-deps).
+Python packages with C dependencies that are not [available on the stack image](https://devcenter.heroku.com/articles/stack-packages) are generally not supported, unless `manylinux` wheels are provided by the package maintainers (common). For recommended solutions, check out [this article](https://devcenter.heroku.com/articles/python-c-deps) for more information.

+# Python: Getting Started
+
+A barebones Django app, which can easily be deployed to Heroku.
+
+This application supports the [Getting Started with Python on Heroku](https://devcenter.heroku.com/articles/getting-started-with-python) article - check it out.
+
+## Running Locally
+
+Make sure you have Python [installed properly](http://install.python-guide.org). Also, install the [Heroku CLI](https://devcenter.heroku.com/articles/heroku-cli) and [Postgres](https://devcenter.heroku.com/articles/heroku-postgresql#local-setup).
+
+```sh
+$ git clone git@github.com:heroku/python-getting-started.git
+$ cd python-getting-started
+
+$ pipenv install
+
+$ createdb python_getting_started
+
+$ python manage.py migrate
+$ python manage.py collectstatic
+
+$ heroku local
+```
+
+Your app should now be running on [localhost:5000](http://localhost:5000/).
+
+## Deploying to Heroku
+
+```sh
+$ heroku create
+$ git push heroku master
+
+$ heroku run python manage.py migrate
+$ heroku open
+```
+or
+
+[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)
+
+## Documentation

+      <ul>
+        <li>This app was deployed to Heroku, either using Git or by using <a href="https://github.com/heroku/python-getting-started">Heroku Button</a> on the repository.</li>
+
+        <li>When Heroku received the source code, it fetched all the dependencies in the <a href="https://github.com/heroku/python-getting-started/blob/master/Pipfile">Pipfile</a>, creating a deployable slug.</li>
+        <li>The platform then spins up a dyno, a lightweight container that provides an isolated environment in which the slug can be mounted and executed.</li>
+        <li>You can scale your app, manage it, and deploy over <a href="https://addons.heroku.com/">150 add-on services</a>, from the Dashboard or CLI.</li>

+        <li>If you deployed this app by deploying the Heroku Button, then in a command line shell, run:</li>
+        <ul>
+          <li><code>git clone https://github.com/heroku/python-getting-started.git</code> - this will create a local copy of the source code for the app</li>
+          <li><code>cd python-getting-started</code> - change directory into the local source code repository</li>
+          <li><code>heroku git:remote -a &lt;your-app-name></code> - associate the Heroku app with the repository</li>
+          <li>You'll now be set up to run the app locally, or <a href="https://devcenter.heroku.com/articles/getting-started-with-python#push-local-changes">deploy changes</a> to Heroku</li>
