Open <a href="http://issues.apache.org/jira/browse/FLINK">Flink’s JIRA</a> and click on the blue <strong>Create</strong> button at the top. Please give detailed information about the problem you encountered and, if possible, add a description that helps to reproduce the problem. Thank you very much.</p>
 
-<p>This section gives you a brief introduction in how to contribute code and documentation to Flink. We maintain both the code and the documentation in the same repository, so the process is essentially the same for both. We use <a href="http://git-scm.com/">git</a> for the code and documentation version control. The documentation is located in the <code>docs/</code> subdirectory of the git repository.</p>

If you have an idea how to improve Flink or have a new feature in mind that would be beneficial for Flink users, please open an issue in <a href="http://issues.apache.org/jira/browse/FLINK">Flink’s JIRA</a>. The improvement or new feature should be described in appropriate detail and include the scope and its requirements if possible. Detailed information is important for a few reasons:</p>

-<ol>
-  <li>
-    <p>The first step is to create yourself a copy of the Flink code base. We suggest to fork the <a href="https://github.com/apache/flink">Flink GitHub Mirror Repository</a> into your own <a href="https://github.com">GitHub</a> account. You need to register on GitHub for that, if you have no account so far.</p>
-  </li>
-  <li>
-    <p>Next, clone your repository fork to your local machine.</p>
-
-    <div class="highlight"><pre><code>git clone https://github.com/&lt;your-user-name&gt;/flink.git
-</code></pre></div>
-  </li>
-  <li>
-    <p>It is typically helpful to switch to a <em>topic branch</em> for the changes. To create a dedicated branch based on the current master, use the following command:</p>
-
-    <div class="highlight"><pre><code>git checkout -b myBranch master
-</code></pre></div>
-  </li>
-  <li>
-    <p>Now you can create your changes, compile the code, and validate the changes. Here are some pointers on how to <a href="https://github.com/apache/flink/#building-apache-flink-from-source">build the code</a>.
-In addition to that, we recommend setting up Eclipse (or IntelliJ) using the “Import Maven Project” feature:</p>
-
-    <ul>
-      <li>Select “Import” from the “File” menu.</li>
-      <li>Expand the “Maven” node, select “Existing Maven Projects”, and click the “Next” button.</li>
-      <li>Select the root directory by clicking on the “Browse” button and navigate to the top folder of the cloned Flink git repository.</li>
-      <li>Ensure that all projects are selected and click the “Finish” button.<br /><br /><!-- newline hack --></li>
-    </ul>
-
-    <p>If you want to work on the Scala code you will need the following plugins:</p>
-
-    <p><strong>Eclipse 4.x</strong>:</p>
-
-    <ul>
-      <li>scala-ide: <code>http://download.scala-ide.org/sdk/e38/scala210/stable/site</code></li>

-    <p>After you have finalized your contribution, verify the compliance with the contribution guidelines (see below), and make the commit. To make the changes easily mergeable, please rebase them to the latest version of the main repository’s master branch. Assuming you created a topic branch (step 3), you can follow this sequence of commands to do that:
-switch to the master branch, update it to the latest revision, switch back to your topic branch, and rebase it on top of the master branch.</p>
-
-    <div class="highlight"><pre><code>git checkout master
-git pull https://github.com/apache/flink.git master
-git checkout myBranch
-git rebase master
-</code></pre></div>
-    <p>Have a look <a href="https://help.github.com/articles/using-git-rebase">here</a> for more information about rebasing commits.</p>
-  </li>
-  <li>
-    <p>Push the contribution back into your fork of the Flink repository.</p>
-
-    <div class="highlight"><pre><code>git push origin myBranch
-</code></pre></div>
-    <p>Go the website of your repository fork (<code>https://github.com/&lt;your-user-name&gt;/flink</code>) and use the “Create Pull Request” button to start creating a pull request. Make sure that the base fork is <code>apache/flink master</code> and the head fork selects the branch with your changes. Give the pull request a meaningful description and send it.</p>
-  </li>
-</ol>
+<p>Detailed information is also required, if you plan to contribute the improvement or feature you proposed yourself. Please read the <a href="/contribute-code.html">Contribute code</a> guide in this case as well. </p>
 
-<h3 id="verifying-the-compliance-of-your-code">Verifying the Compliance of your Code</h3>
+<hr />
 
-<p>Before sending a patch or pull request, please verify that it complies with the guidelines of the project. While we try to keep the set of guidelines small and easy, it is important to follow those rules in order to guarantee good code quality, to allow efficient reviews, and to allow committers to easily merge your changes.</p>
+<h2 id="help-others-and-join-the-discussions">Help others and join the discussions</h2>
 
-<p>Please have a look at the <a href="/coding-guidelines.html">coding guidelines</a> for a guide to the format of code and pull requests.</p>
+<p>Most communication in the Apache Flink community happens on two mailing lists:</p>
 
-<p>Most important of all, verify that your changes are correct and do not break existing functionality. Run the existing tests by calling <code>mvn verify</code> in the root directory of the repository, and make sure that the tests succeed. We encourage every contributor to use a <em>continuous integration</em> service that will automatically test the code in your repository whenever you push a change. Flink is pre-configured for <a href="http://docs.travis-ci.com/">Travis CI</a>, which can be easily enabled for your private repository fork (it uses GitHub for authentication, so you don’t need an additional account). Simply add the <em>Travis CI</em> hook to your repository (<em>settings –&gt; webhooks &amp; services –&gt; add service</em>) and enable tests for the “flink” repository on <a href="https://travis-ci.org/profile">Travis</a>.</p>
+<ul>
+  <li>The user mailing lists <code>user@flink.apache.org</code> is the place where users of Apache Flink ask questions and seek for help or advice. Joining the user list and helping other users is a very good way to contribute to Flink’s community. Furthermore, there is the <a href="http://stackoverflow.com/questions/tagged/apache-flink">[apache-flink]</a> tag on Stack Overflow if you’d like to help Flink users (and harvest some points) there.</li>
+  <li>The development mailing list <code>dev@flink.apache.org</code> is the place where Flink developers exchange ideas and discuss new features, upcoming releases, and the development process in general. If you are interested in contributing code to Flink, you should join this mailing list.</li>
+</ul>
 
-<p>When contributing documentation, please review the rendered HTML versions of the documents you changed. You can look at the HTML pages by using the rendering script in preview mode.</p>
+<p>You are very welcome to <a href="/community.html#mailing-lists">subscribe to both mailing lists</a>. In addition to the user list, there is also a <a href="/community.html#irc">Flink IRC</a> channel that you can join to talk to other users and contributors.</p>
 
-<div class="highlight"><pre><code>cd docs

-<h2 id="contribute-changes-to-the-website">Contribute changes to the Website</h2>
+<h2 id="test-a-release-candidate">Test a release candidate</h2>
 
-<p>The website of Apache Flink is hosted in a separate Git repository. We suggest making a fork of the <a href="https://github.com/apache/flink-web">flink-web GitHub mirror repository</a>.</p>
+<p>Apache Flink is continuously improved by its active community. Every few weeks, we release a new version of Apache Flink with bug fixes, improvements, and new features. The process of releasing a new version consists of the following steps:</p>
 
-<p>To make changes to the website, you have to checkout its source code first. The website resides in the <code>asf-site</code> branch of the repository:</p>
+<ol>
+  <li>Building a new release candidate and starting a vote (usually for 72 hours).</li>
+  <li>Testing the release candidate and voting (<code>+1</code> if no issues were found, <code>-1</code> if the release candidate has issues).</li>
+  <li>Going back to step 1 if the release candidate had issues otherwise we publish the release.</li>
+</ol>
 
-<div class="highlight"><pre><code>git clone -b asf-site https://github.com/&lt;your-user-name&gt;/flink-web.git
-cd flink-web
-</code></pre></div>
+<p>Our wiki contains a page that summarizes the <a href="https://cwiki.apache.org/confluence/display/FLINK/Releasing">test procedure for a release</a>. Release testing is a big effort if done by a small group of people but can be easily scaled out to more people. The Flink community encourages everybody to participate in the testing of a release candidate. By testing a release candidate, you can ensure that the next Flink release is working properly for your setup and help to improve the quality of releases. </p>
 
-<p>The <code>flink-web</code> directory contains the files that we use to build the website. We use <a href="http://jekyllrb.com/">Jekyll</a> to generate static HTML files for the website.</p>
+<hr />
 
-<h3 id="files-and-directories-in-the-website-git-repository">Files and Directories in the website git repository</h3>
+<h2 id="contribute-code">Contribute code</h2>
 
-<p>The files and directories in the website git repository have the following roles:</p>
+<p>Apache Flink is maintained, improved, and extended by code contributions of volunteers. The Apache Flink community encourages anybody to contribute source code. In order to ensure a pleasant contribution experience for contributors and reviewers and to preserve the high quality of the code base, we follow a contribution process that is explained in our <a href="/contribute-code.html">Contribute code</a> guide. The guide does also include instructions to setup a development environment, our coding guidelines and code style, and explains how to submit a code contribution.</p>
 
-<ul>
-  <li>all files ending with <code>.md</code> are <a href="http://daringfireball.net/projects/markdown/">Markdown</a> files. Those are the input for the HTML files.</li>
-  <li>regular directories (not starting with an underscore (<code>_</code>)) contain also <code>.md</code> files. The directory structure is also represented in the generated HTML files.</li>
-  <li>the <code>_posts</code> directory contains one Markdown file for each blog post on the website. To contribute a post, just add a new file there.</li>
-  <li>the <code>_includes/</code> directory contains includeable files such as the navigation bar or the footer.</li>
-  <li>the <code>docs/</code> directory contains copies of the documentation of Flink for different releases. There is a directory inside <code>docs/</code> for each stable release and the latest SNAPSHOT version. The build script is taking care of the maintenance of this directory.</li>
-  <li>the <code>content/</code> directory contains the generated HTML files from Jekyll. It is important to place the files in this directory since the Apache Infrastructure to host the Flink website is pulling the HTML content from his directory. (For committers: When pushing changes to the website repository, push also the updates in the <code>content/</code> directory!)</li>
-  <li>see the section below for the <code>build.sh</code> script.</li>
-</ul>
+<p><strong>Please read the <a href="/contribute-code.html">Contribute code</a> guide before you start to work on a code contribution.</strong></p>
 
-<h3 id="the-buildsh-script">The <code>build.sh</code> script</h3>
+<p>Please do also read the <a href="/how-to-contribute.html#submit-a-contributor-license-agreement">Submit a Contributor License Agreement</a> Section.</p>
 
-<p>The <code>build.sh</code> script creates HTML files from the input Markdown files. Use the <code>-p</code> flag to let Jekyll serve a <strong>p</strong>review of the website on <code>http://localhost:4000/</code>.</p>
+<h3 class="no_toc" id="looking-for-an-issue-to-work-on">Looking for an issue to work on?</h3>
 
-<p>The build script also takes care of maintaining the <code>docs/</code> directory. Set the <code>-u</code> flag to <strong>u</strong>pdate documentation. This includes fetching the Flink git repository and copying different versions of the documentation.</p>
+<p>We maintain a list of all known bugs, proposed improvements and suggested features in <a href="https://issues.apache.org/jira/browse/FLINK/?selectedTab=com.atlassian.jira.jira-projects-plugin:issues-panel">Flink’s JIRA</a>. Issues that we believe are good tasks for new contributors are tagged with a special “starter” tag. Those tasks are supposed to be rather easy to solve and will help you to become familiar with the project and the contribution process. </p>
 
-<h2 id="how-to-become-a-committer">How to become a committer</h2>
+<p>Please have a look at the list of <a href="https://issues.apache.org/jira/issues/?jql=project%20%3D%20FLINK%20AND%20resolution%20%3D%20Unresolved%20AND%20labels%20%3D%20starter%20ORDER%20BY%20priority%20DESC">starter issues</a>, if you are looking for an issue to work on.

Feel free to ask questions about issues that you would be interested in working on.</p>
 
-<p>There is no strict protocol for becoming a committer. Candidates for new committers are typically people that are active contributors and community members.</p>
+<hr />
 
-<p>Being an active community member means participating on mailing list discussions, helping to answer questions, being respectful towards others, and following the meritocratic principles of community management. Since the “Apache Way” has a strong focus on the project community, this part is very important.</p>
+<h2 id="contribute-documentation">Contribute documentation</h2>
 
-<p>Of course, contributing code to the project is important as well. A good way to start is contributing improvements, new features, or bugfixes. You need to show that you take responsibility for the code that you contribute, add tests/documentation, and help maintaining it.</p>
+<p>Good documentation is crucial for any kind of software. This is especially true for sophisticated software systems such as distributed data processing engines like Apache Flink. The Apache Flink community aims to provide concise, precise, and complete documentation and welcomes any contribution to improve Apache Flink’s documentation.</p>
 
-<p>Finally, candidates for new committers are suggested by current committers, mentors, or PMC members, and voted upon by the PMC.</p>
+<ul>
+  <li>Please report missing, incorrect, or out-dated documentation as a <a href="http://issues.apache.org/jira/browse/FLINK">JIRA issue</a>.</li>
+  <li>Flink’s documentation is written in Markdown and located in the <code>docs</code> folder in <a href="/community.html#main-source-repositories">Flink’s source code repository</a>. See the <a href="/contribute-documentation.html">Contribute documentation</a> guidelines for detailed instructions for how to update and improve the documentation and to contribute your changes.</li>

+<p>Please submit a contributor license agreement to the Apache Software Foundation (ASF) if you would like to contribute to Apache Flink. The following quote from <a href="http://www.apache.org/licenses/#clas">http://www.apache.org/licenses</a> gives more information about the ICLA and CCLA and why they are necessary.</p>
 
-<h2 id="snapshots-nightly-builds">Snapshots (Nightly Builds)</h2>
+<blockquote>
+  <p>The ASF desires that all contributors of ideas, code, or documentation to the Apache projects complete, sign, and submit (via postal mail, fax or email) an <a href="http://www.apache.org/licenses/icla.txt">Individual Contributor License Agreement</a> (CLA) [ <a href="http://www.apache.org/licenses/icla.pdf">PDF form</a> ]. The purpose of this agreement is to clearly define the terms under which intellectual property has been contributed to the ASF and thereby allow us to defend the project should there be a legal dispute regarding the software at some future time. A signed CLA is required to be on file before an individual is given commit rights to an ASF project.</p>
 
-<p>Apache Flink <code>0.10-SNAPSHOT</code> is our latest development version.</p>
+  <p>For a corporation that has assigned employees to work on an Apache project, a <a href="http://www.apache.org/licenses/cla-corporate.txt">Corporate CLA</a> (CCLA) is available for contributing intellectual property via the corporation, that may have been assigned as part of an employment agreement. Note that a Corporate CLA does not remove the need for every developer to sign their own CLA as an individual, to cover any of their contributions which are not owned by the corporation signing the CCLA.</p>
 
-<p>You can download a packaged version of our nightly builds, which include
-the most recent development code. You can use them if you need a feature

+
+<p>Committers are community members that have write access to the project’s repositories, i.e., they can modify the code, documentation, and website by themselves and also accept other contributions. </p>
+
+<p>There is no strict protocol for becoming a committer. Candidates for new committers are typically people that are active contributors and community members.</p>
+
+<p>Being an active community member means participating on mailing list discussions, helping to answer questions, verifying release candidates, being respectful towards others, and following the meritocratic principles of community management. Since the “Apache Way” has a strong focus on the project community, this part is <em>very</em> important.</p>

+<p>Of course, contributing code and documentation to the project is important as well. A good way to start is contributing improvements, new features, or bug fixes. You need to show that you take responsibility for the code that you contribute, add tests and documentation, and help maintaining it.</p>

+<p>The <a href="http://flink.apache.org">Apache Flink website</a> presents Apache Flink and its community. It serves several purposes including:</p>
+
+<ul>
+  <li>Informing visitors about Apache Flink and its features.</li>
+  <li>Encouraging visitors to download and use Flink.</li>
+  <li>Encouraging visitors to engage with the community.</li>
+</ul>
+
+<p>We welcome any contribution to improve our website. This document contains all information that is necessary to improve Flink’s website.</p>

+
+<h2 id="obtain-the-website-sources">Obtain the website sources</h2>
+
+<p>The website of Apache Flink is hosted in a dedicated <a href="http://git-scm.com/">git</a> repository which is mirrored to Github at <a href="https://github.com/apache/flink-web">https://github.com/apache/flink-web</a>.</p>
+
+<p>The easiest way to contribute website updates is to fork <a href="https://github.com/apache/flink-web">the mirrored website repository on Github</a> into your own Github account by clicking on the fork button at the top right. If you have no Github account, you can create one for free.</p>
+
+<p>Next, clone your fork to your local machine.</p>
+
+<div class="highlight"><pre><code>git clone https://github.com/&lt;your-user-name&gt;/flink-web.git
+</code></pre></div>
+
+<p>The <code>flink-web</code> directory contains the cloned repository. The website resides in the <code>asf-site</code> branch of the repository. Run the following commands to enter the directory and switch to the <code>asf-site</code> branch.</p>
+
+<div class="highlight"><pre><code>cd flink-web
+git checkout asf-site
+</code></pre></div>
+
+<h2 id="directory-structure-and-files">Directory structure and files</h2>
+
+<p>Flink’s website is written in <a href="http://daringfireball.net/projects/markdown/">Markdown</a>. Markdown is a lightweight markup language which can be translated to HTML. We use <a href="http://jekyllrb.com/">Jekyll</a> to generate static HTML files from Markdown.</p>
+
+<p>The files and directories in the website git repository have the following roles:</p>
+
+<ul>
+  <li>All files ending with <code>.md</code> are Markdown files. These files are translated into static HTML files.</li>
+  <li>Regular directories (not starting with an underscore (<code>_</code>)) contain also <code>.md</code> files. The directory structure is reflected in the generated HTML files and the published website.</li>
+  <li>The <code>_posts</code> directory contains blog posts. Each blog post is written as one Markdown file. To contribute a post, add a new file there.</li>
+  <li>The <code>_includes/</code> directory contains includeable files such as the navigation bar or the footer.</li>
+  <li>The <code>docs/</code> directory contains copies of the documentation of Flink for different releases. There is a directory inside <code>docs/</code> for each stable release and the latest SNAPSHOT version. The build script is taking care of the maintenance of this directory.</li>
+  <li>The <code>content/</code> directory contains the generated HTML files from Jekyll. It is important to place the files in this directory since the Apache Infrastructure to host the Flink website is pulling the HTML content from his directory. (For committers: When pushing changes to the website git, push also the updates in the <code>content/</code> directory!)</li>
+</ul>
+
+<h2 id="update-or-extend-the-documentation">Update or extend the documentation</h2>
+
+<p>You can update and extend the website by modifying or adding Markdown files or any other resources such as CSS files. To verify your changes start the build script in preview mode.</p>
+
+<div class="highlight"><pre><code>./build.sh -p
+</code></pre></div>
+
+<p>The script compiles the Markdown files into HTML and starts a local webserver. Open your browser at <code>http://localhost:4000</code> to view the website including your changes. The served website is automatically re-compiled and updated when you modify and save any file and refresh your browser.</p>
+
+<p>Please feel free to ask any questions you have on the developer mailing list.</p>
+
+<h2 id="submit-your-contribution">Submit your contribution</h2>
+
+<p>The Flink project accepts website contributions through the <a href="https://github.com/apache/flink-web">GitHub Mirror</a> as <a href="https://help.github.com/articles/using-pull-requests">Pull Requests</a>. Pull requests are a simple way of offering a patch by providing a pointer to a code branch that contains the changes.</p>
+
+<p>To prepare and submit a pull request follow these steps.</p>
+
+<ol>
+  <li>
+    <p>Commit your changes to your local git repository. <strong>Please Make sure that your commit does not include translated files (any files in the <code>content/</code> directory).</strong> Unless your contribution is a major rework of the website, please squash it into a single commit.</p>
+  </li>
+  <li>
+    <p>Push the commit to a dedicated branch of your fork of the Flink repository at Github.</p>
+
+    <p><code>
+ git push origin myBranch
+</code></p>
+  </li>
+  <li>
+    <p>Go the website of your repository fork (<code>https://github.com/&lt;your-user-name&gt;/flink-web</code>) and use the “Create Pull Request” button to start creating a pull request. Make sure that the base fork is <code>apache/flink-web asf-site</code> and the head fork selects the branch with your changes. Give the pull request a meaningful description and submit it.</p>
+  </li>
+</ol>
+
+<h2 id="committer-section">Committer section</h2>

 <p>Our team has been working hard during the last few months to create an improved and stable Stratosphere version. The new version comes with many new features, usability and performance improvements in all levels, including a new Scala API for the concise specification of programs, a Pregel-like API, support for Yarn clusters, and major performance improvements. The system features now first-class support for iterative programs and thus covers traditional analytical use cases as well as data mining and graph processing use cases with great performance.</p>

 <p>The high-level language Meteor now natively serializes JSON trees for greater performance and offers additional operators and file formats. We greatly empowered the user to write crispier scripts by adding second-order functions, multi-output operators, and other syntactical sugar. For developers of Meteor packages, the API is much more comprehensive and allows to define custom data types that can be easily embedded in JSON trees through ad-hoc byte code generation.</p>
