     ## Mesos without DC/OS
     
    -Let's take a look at how to setup Flink on Mesos without DC/OS. 
    +You can also run Mesos without DC/OS.
     
    -### Prerequisites
    +### Installing Mesos
     
    -Please follow the
    -[instructions on how to setup Mesos on the official 
website](http://mesos.apache.org/documentation/latest/). 
    +Please follow the [instructions on how to setup Mesos on the official 
website](http://mesos.apache.org/documentation/latest/getting-started/).
    +
    +After installation you have to configure the set of master and agent nodes 
by creating the files `MESOS_HOME/etc/mesos/masters` and 
`MESOS_HOME/etc/mesos/slaves`.
    +These files contain in each row a single hostname on which the respective 
component will be started (assuming SSH access to these nodes).
    +
    +Next you have to create `MESOS_HOME/etc/mesos/mesos-master-env.sh` or use 
the template found in the same directory.
    +In this file, you have to define
    +
    +    export MESOS_work_dir=WORK_DIRECTORY
    +
    +and it is recommended to uncommment
    +
    +    export MESOS_log_dir=LOGGING_DIRECTORY
    +
    +
    +In order to configure the Mesos agents, you have to create 
`MESOS_HOME/etc/mesos/mesos-agent-env.sh` or use the template found in the same 
directory.
    +You have to configure
    +
    +    export MESOS_master=MASTER_HOSTNAME:MASTER_PORT
    +
    +and uncomment
    +
    +    export MESOS_log_dir=LOGGING_DIRECTORY
    +    export MESOS_work_dir=WORK_DIRECTORY
    +
    +#### Mesos Library
    +
    +In order to run Java applications with Mesos you have to export 
`MESOS_NATIVE_JAVA_LIBRARY=MESOS_HOME/lib/libmesos.so`.
    +
    +#### Deploying Mesos
    +
    +In order to start your mesos cluster, use the deployment script 
`MESOS_HOME/sbin/mesos-start-cluster.sh`.
    +In order to stop your mesos cluster, use the deployment script 
`MESOS_HOME/sbin/mesos-stop-cluster.sh`.
    +More information about the deployment scripts can be found 
[here](http://mesos.apache.org/documentation/latest/deploy-scripts/).
    +
    +### Installing Marathon
    +
    +Optionally, you may also [install 
Marathon](https://mesosphere.github.io/marathon/docs/) which will be necessary 
to run Flink in high availability (HA) mode.
     
     ### Optional dependencies
    --- End diff --
    
    This title is a bit not synced with the other title changes: "Installing 
Marathon" was singled out if "Optional dependencies", even though Marathon is 
still optional.
    
    Perhaps "Installing Maration (Optional)" and change this also to 
"Installing a Distributed Filesystem (Optional)".
