+## Introduction
+
+FlinkML is designed to make learning from your data a straight-forward
process, abstracting away
+the complexities that usually come with having to deal with big data
learning tasks. In this
+quick-start guide we will show just how easy it is to solve a simple
supervised learning problem
+using FlinkML. But first some basics, feel free to skip the next few lines
if you're already
+familiar with Machine Learning (ML).
+
+As defined by Murphy [1] ML deals with detecting patterns in data, and
using those
+learned patterns to make predictions about the future. We can categorize
most ML algorithms into
+two major categories: Supervised and Unsupervised Learning.
+
+* **Supervised Learning** deals with learning a function (mapping) from a
set of inputs
+(features) to a set of outputs. The learning is done using a *training
set* of (input,
+output) pairs that we use to approximate the mapping function. Supervised
learning problems are
+further divided into classification and regression problems. In
classification problems we try to
+predict the *class* that an example belongs to, for example whether a user
is going to click on
+an ad or not. Regression problems one the other hand, are about predicting
(real) numerical
+values, often called the dependent variable, for example what the
temperature will be tomorrow.
+
+* **Unsupervised Learning** deals with discovering patterns and
regularities in the data. An example
+of this would be *clustering*, where we try to discover groupings of the
data from the
+descriptive features. Unsupervised learning can also be used for feature
selection, for example
+through [principal components
analysis](https://en.wikipedia.org/wiki/Principal_component_analysis).
+
+## Linking with FlinkML
+
+In order to use FlinkML in you project, first you have to
+[set up a Flink
program](http://ci.apache.org/projects/flink/flink-docs-master/apis/programming_guide.html#linking-with-flink).
+Next, you have to add the FlinkML dependency to the `pom.xml` of your
project:
+
+{% highlight xml %}
+<dependency>
+ <groupId>org.apache.flink</groupId>
+ <artifactId>flink-ml</artifactId>
+ <version>{{site.version }}</version>

Hmm I was not aware of this ;-)

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastruct...@apache.org or file a JIRA ticket
with INFRA.
