   == Contributing
   
  -Spring Cloud is released under the non-restrictive Apache 2.0 license. If you would like
  -to contribute something, or simply want to hack on the code this document should help
  -you get started.
  +Spring Cloud is released under the non-restrictive Apache 2.0 license,
  +and follows a very standard Github development process, using Github
  +tracker for issues and merging pull requests into master. If you want
  +to contribute even something trivial please do not hesitate, but
  +follow the guidelines below.
   
   === Sign the Contributor License Agreement
   Before we accept a non-trivial patch or pull request we will need you to sign the
  
positive.code: implement common patterns like single sign on, token relay and token
  exchange.
  
  == Building
  
  :jdkversion: 1.7
  
  === Basic Compile and Test
  
  To build the source you will need to install
  http://maven.apache.org/run-maven/index.html[Apache Maven] v3.0.6 or above and JDK {jdkversion}.
  
  Spring Cloud uses Maven for most build-related activities, and you
  should be able to get off the ground quite quickly by cloning the
  project you are interested in and typing
  
  ----
  $ mvn install -s .settings.xml
  ----
  
  NOTE: You may need to increase the amount of memory available to Maven by setting
  a `MAVEN_OPTS` environment variable with the value `-Xmx512m -XX:MaxPermSize=128m`
  
  The `.settings.xml` is only required the first time (or after updates
  to dependencies). It is there to provide repository declarations so
  that those do not need to be hard coded in the project poms.
  
  For hints on how to build the project look in `.travis.yml` if there
  is one. There should be a "script" and maybe "install" command. Also
  look at the "services" section to see if any services need to be
  running locally (e.g. mongo or rabbit).  Ignore the git-related bits
  that you might find in "before_install" since they will be able git
  credentials and you already have those.
  
  If you need mongo, rabbit or redis, see the README in the https://github.com/spring-cloud-samples/scripts[scripts
  demo repository] for
  instructions. For example consider using the "fig.yml" with
  http://www.fig.sh/[Fig] to run them in Docker containers.
  
  === Documentation
  
  
negative.code: any changes in the README it will then show up after a Maven build as
  a modified file in the correct place. Just commit it and push the change.
  
  === Working with the code
  If you don't have an IDE preference we would recommend that you use
