+# Heroku Buildpack: Python
+
+This is the official [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [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 (e.g. scipy) are [not compatible](https://devcenter.heroku.com/articles/python-c-deps). 
+
+See it in Action
+----------------
+
+Deploying a Python application couldn't be easier:
+
+    $ ls
+    Procfile  requirements.txt  web.py
+
+    $ heroku create --buildpack heroku/python
+
+    $ git push heroku master
+    ...
+    -----> Python app detected
+    -----> Installing python-2.7.12
+         $ pip install -r requirements.txt
+           Collecting requests (from -r requirements.txt (line 1))
+             Downloading requests-2.10.0-py2.py3-none-any.whl (501kB)
+           Installing collected packages: requests
+           Successfully installed requests-2.10.0
+           
+    -----> Discovering process types
+           Procfile declares types -> (none)
+
+A `requirements.txt` file must be present at the root of your application's repository.
+
+You can also specify the latest production release of this buildpack for upcoming builds of an existing application:
+
+    $ heroku buildpacks:set heroku/python
+
+
+Specify a Python Runtime
+------------------------
+
+Specific versions of the Python runtime can be specified with a `runtime.txt` file:
+
+    $ cat runtime.txt
+    python-3.5.2
+
+Runtime options include:
+
+- `python-2.7.12`
+- `python-3.5.2`
+- `pypy-5.3.1` (unsupported, experimental)
+
+Other [unsupported runtimes](https://github.com/heroku/heroku-buildpack-python/tree/master/builds/runtimes) are available as well. Use at your own risk.

-Heroku buildpack: Python
-========================
-
-This is a [Heroku buildpack](http://devcenter.heroku.com/articles/buildpacks) for Python apps, powered by [pip](http://www.pip-installer.org/).
-
-
-Usage
-----
-
-Example usage:
-
-    $ ls
-    Procfile  requirements.txt  web.py
-
-    $ heroku create --buildpack git://github.com/heroku/heroku-buildpack-python.git
-
-    $ git push heroku master

-    -----> Python app detected
-    -----> No runtime.txt provided; assuming python-2.7.8.
-    -----> Preparing Python runtime (python-2.7.8)
-    -----> Installing Setuptools (3.6)
-    -----> Installing Pip (1.5.6)
-    -----> Installing dependencies using Pip (1.5.6)
-           Downloading/unpacking requests (from -r requirements.txt (line 1))
-           Installing collected packages: requests
-           Successfully installed requests
-           Cleaning up...
-    -----> Discovering process types
-           Procfile declares types -> (none)
-
-You can also add it to upcoming builds of an existing application:
-
-    $ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git
-
-The buildpack will detect your app as Python if it has the file `requirements.txt` in the root.
-
-It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
-
-Specify a Runtime
-----------------
-
-You can also provide arbitrary releases Python with a `runtime.txt` file.
-
-    $ cat runtime.txt
-    python-3.4.1
-
-Runtime options include:
-
- python-2.7.8
- python-3.4.1
- pypy-1.9 (experimental)
-
-Other [unsupported runtimes](https://github.com/heroku/heroku-buildpack-python/tree/master/builds/runtimes) are available as well.
