 ## General Instructions
 
 You don't have to clone this repo, you should be able to use this image as a base image for your project.
 
-There are four image tags:
+There are several image tags, for each one, there's a template repo (a `.zip` file that you can download from above, in the "**Examples**" section):
 
-* **`flask`** (also `latest`): An image based on the [**tiangolo/uwsgi-nginx**](https://hub.docker.com/r/tiangolo/uwsgi-nginx/) image. This image includes Flask and a sample app.
+* **`flask`** (also `latest` and `flask-python2.7`): An image based on the [**tiangolo/uwsgi-nginx**](https://hub.docker.com/r/tiangolo/uwsgi-nginx/) image. This image includes Flask and a sample app.
 
 The image [**tiangolo/uwsgi-nginx**](https://hub.docker.com/r/tiangolo/uwsgi-nginx/) has uWSGI and Nginx installed in the same container and is made to be the base of this image.
 
 Use `FROM tiangolo/uwsgi-nginx-flask:flask` in your `Dockerfile` to use this image. (This would be the most general purpose tag image).
 
-You can also use the example template project: [**example-flask**](<https://github.com/tiangolo/uwsgi-nginx-flask-docker/releases/download/v0.1.1/example-flask.zip>).
-
 * **`flask-upload`**: The same as **`flask`** but configuring Nginx to allow uploads of up to 100 MB (the default is 1 MB).
 
 Use `FROM tiangolo/uwsgi-nginx-flask:flask-upload` in your `Dockerfile` to use this image. (This would be the most general purpose tag image).
 
-You can also use the example template project: [**example-flask-upload**](<https://github.com/tiangolo/uwsgi-nginx-flask-docker/releases/download/v0.1.2/example-flask-upload.zip>).
-
 * **`flask-index`**: An image based on the **`flask`** image (above), but optimizing the configuration to make Nginx serve `/app/static/index.html` directly (instead of going through uWSGI and your code) when requested for `/`.
 
 This is specially helpful (and efficient) if you are building a single-page app without Jinja2 templates (as with Angular JS) and using Flask as an API / back-end.
 
 Use `FROM tiangolo/uwsgi-nginx-flask:flask-index` in your `Dockerfile` to use this image.
 
-You can also use the example template project: [**example-flask-index**](<https://github.com/tiangolo/uwsgi-nginx-flask-docker/releases/download/v0.1.1/example-flask-index.zip>).
-
 * **`flask-index-upload`**: The same as **`flask-index`** but configuring Nginx to allow uploads of up to 100 MB (the default is 1 MB).
 
 Use `FROM tiangolo/uwsgi-nginx-flask:flask-index-upload` in your `Dockerfile` to use this image. (This would be the most general purpose tag image).
 
-You can also use the example template project: [**example-flask-index-upload**](<https://github.com/tiangolo/uwsgi-nginx-flask-docker/releases/download/v0.1.2/example-flask-index-upload.zip>).
+* **Python 3.5**: There is a version of all the images and example templates above using Python 3.5. The usage is very similiar to the usage of the normal (Python 2.7) version, but using the equivalent `python3.5` tag (you can see all the available tags on the top). Nevertheless, [Python 2.7 is still the default as the Flask maintainers use it as default and port the code to Python 3.5](http://flask.pocoo.org/docs/0.11/python3/) and Python 2.7 is still the most used and supported version.
