 ## Setup
 
-### Setup Requirements **OPTIONAL**
+### Setup Requirements
 
-If your module requires anything extra before setting up (pluginsync enabled,
-another module, etc.), mention it here.
+The puppet-hdm module needs puppetlabs/stdlib as we use some of the stdlib data types.
 
-If your most recent release breaks compatibility or requires particular steps
-for upgrading, you might want to include an additional "Upgrading" section here.
+If you want to make use of the docker container, you need the following module:
 
-### Beginning with hdm
-
-The very basic steps needed for a user to get the module up and running. This
-can include setup steps, if necessary, or it can be an example of the most basic
-use of the module.
-
-## Usage
-
-Include usage examples for common use cases in the **Usage** section. Show your
-users how to use your module to solve problems, and be sure to include code
-examples. Include three to five examples of the most important or common tasks a
-user can accomplish with your module. Show users how to accomplish more complex
-tasks that involve different types, classes, and functions working in tandem.
-
-## Reference
-
-This section is deprecated. Instead, add reference information to your code as
-Puppet Strings comments, and then use Strings to generate a REFERENCE.md in your
-module. For details on how to add code comments and generate documentation with
-Strings, see the [Puppet Strings documentation][2] and [style guide][3].
-
-If you aren't ready to use Strings yet, manually create a REFERENCE.md in the
-root of your module directory and list out each of your module's classes,
-defined types, facts, functions, Puppet tasks, task plans, and resource types
-and providers, along with the parameters for each.
+- puppetlabs/docker - min version 4.4.0
 
-For each element (class, defined type, function, and so on), list:
+If you want to install HDM using Puppet Ruby, you need the following modules:
 
-* The data type, if applicable.
-* A description of what the element does.
-* Valid values, if the data type doesn't make it obvious.
-* Default value, if any.
+- puppetlabs/vcsrepo - min version 5.2.0
+- puppet/systemd     - min version 3.10.0
 
-For example:
+### Beginning with hdm
 
-```
-### `pet::cat`
+The most simple approach is to just include the hdm class:
 
-#### Parameters
+    include hdm
 
-##### `meow`
+This will install HDM as docker container.
 
-Enables vocalization in your cat. Valid options: 'string'.
+## Reference
 
-Default: 'medium-loud'.
-```
+Please check the [REFERENCE.md](REFERENCE.md) file.
 
 ## Limitations
 
-In the Limitations section, list any incompatibilities, known issues, or other
-warnings.
-
-## Development
-
-In the Development section, tell other users the ground rules for contributing
-to your project and how they should submit their work.
-
-## Release Notes/Contributors/Etc. **Optional**
-
-If you aren't using changelog, put your release notes here (though you should
-consider using changelog). You can also add any additional sections you feel are
-necessary or important to include here. Please use the `##` header.

+On SLES we can not use the puppetlabs/docker module.
+Instead set the manage_docker parameter to false and take care on docker package and service by yourself.
