+*********************************************
+Guidelines for VMware REST module development
+*********************************************
+
+The Ansible VMware REST collection (on `Galaxy <https://galaxy.ansible.com/vmware/vmware_rest>`_, source code `repository <https://github.com/ansible-collections/vmware.vmware_rest>`_) is maintained by Red Hat and the community.

+
+Contribution process
+====================
+
+The modules of the vmware_rest collection are autogenerated by another tool called `vmware_rest_code_generator <https://github.com/ansible-collections/vmware_rest_code_generator>`.
+
+If you would like to contribute a change, we would appreciate if you:
+
+- submit a GitHub Pull Request (PR) against the vmware_rest_code_generator project
+- but also ensure the generated modules are compliant with our quality criteria.
+
+Requirements
+============
+
+You will need:
+
+- Python 3.6 or greater
+- the `tox <https://tox.readthedocs.io/en/latest/install.html>` command
+
+
+vmware_rest_code_generator
+==========================
+
+Your contribution should follow the coding style of `Black <https://github.com/psf/black>`.
+To run the code formatter, just run:
+
+.. code-block:: shell
+
+    tox -e black
+
+To regenerate the vmware_rest collection, you can use the following commands:
+
+.. code-block:: shell
+
+    tox -e refresh_modules -- --target-dir ~/.ansible/collections/ansible_collections/vmware/vmware_rest
+
+If you also want to update the EXAMPLE section of the modules, run:
+
+.. code-block:: shell
+
+    tox -e refresh_examples -- --target-dir ~/.ansible/collections/ansible_collections/vmware/vmware_rest
+
+Testing with ansible-test
+=========================
+
+All the modules are covered by a functional test. The tests are located in the `tests/integration/targets/`.
+
+To run the tests, you will need a vcenter instance and an ESXi.
+
+black code formatter
+^^^^^^^^^^^^^^^^^^^^
+
+We follow the coding style of `Black <https://github.com/psf/black>`.
+You can run the code formatter with the following command.
+
+
+.. code-block:: shell
+
+    tox -e black
+
+sanity tests
+^^^^^^^^^^^^
+
+Here we use Python 3.8, the minimal version is 3.6.
+
+.. code-block:: shell
+
+    tox -e black
+    ansible-test sanity --debug --requirements --local --skip-test future-import-boilerplate --skip-test metaclass-boilerplate --python 3.8 -vvv
+
+
+integration tests
+^^^^^^^^^^^^^^^^^
+
+These tests should be run against your test environment.
+
+..warning:: The test suite will delete all the existing DC from your test environment. 
+
+First, prepare a configuration file, we call it `/tmp/inventory-vmware_rest` in
+this example:
+
+.. code-block:: ini
+
+    [vmware_rest]
+    localhost ansible_connection=local ansible_python_interpreter=python
+    
+    [vmware_rest:vars]
+    vcenter_hostname=vcenter.test
+    vcenter_username=administrator@vsphere.local
+    vcenter_password=kLRy|FXwZSHXW0w?Q:sO
+    esxi1_hostname=esxi1.test
+    esxi1_username=zuul
+    esxi1_password=f6QYNi65k05kv8m56
+
+
+To run the tests, use the following command. You may want to adjust the Python version.
+
+.. code-block:: shell
+
+    ansible-test network-integration --diff --no-temp-workdir --python 3.8 --inventory /tmp/inventory-vmware_rest zuul/
