+Alibaba Cloud Compute Services Guide
+====================================
+
+Introduction
+````````````
+
+The community.general collection contains several modules for controlling and managing Alibaba Cloud Compute Services (Alicloud).  This guide
+explains how to use the Alicloud Ansible modules together.
+
+All Alicloud modules require ``footmark`` - install it on your control machine with ``pip install footmark``.
+
+Cloud modules, including Alicloud modules, are usually executed on your local machine (the control machine) with ``connection: local``, rather than on remote machines defined in your hosts.
+
+Normally, you'll use the following pattern for plays that provision Alicloud resources:
+
+.. code-block:: yaml
+
+    - hosts: localhost
+      connection: local
+      vars:
+        - ...
+      tasks:
+        - ...
+
+Authentication
+``````````````
+
+You can specify your Alicloud authentication credentials (access key and secret key) by passing them as
+environment variables or by storing them in a vars file.
+
+To pass authentication credentials as environment variables:
+
+.. code-block:: console
+
+    export ALICLOUD_ACCESS_KEY='Alicloud123'
+    export ALICLOUD_SECRET_KEY='AlicloudSecret123'
+
+To store authentication credentials in a vars file, encrypt them with :ref:`Ansible Vault <vault>` to keep them secure, then list them:
+
+.. code-block:: yaml
+
+    ---
+    alicloud_access_key: "--REMOVED--"
+    alicloud_secret_key: "--REMOVED--"
+
+Note that if you store your credentials in a vars file, you need to refer to them in each Alicloud module. For example:
+
+.. code-block:: yaml+jinja
+
+    - community.general.ali_instance:
+        alicloud_access_key: "{{ alicloud_access_key }}"
+        alicloud_secret_key: "{{ alicloud_secret_key }}"
+        image_id: "..."
+
+Provisioning
+````````````
+
+Alicloud modules create Alicloud ECS instances (:ansplugin:`community.general.ali_instance#module`) and retrieve information on these (:ansplugin:`community.general.ali_instance_info#module`).
+
+You can use the ``count`` parameter to control the number of resources you create or terminate. For example, if you want exactly 5 instances tagged ``NewECS``, set the ``count`` of instances to 5 and the ``count_tag`` to ``NewECS``, as shown in the last task of the example playbook below. If there are no instances with the tag ``NewECS``, the task creates 5 new instances. If there are 2 instances with that tag, the task creates 3 more. If there are 8 instances with that tag, the task terminates 3 of those instances.
+
+If you do not specify a ``count_tag``, the task creates the number of instances you specify in ``count`` with the ``instance_name`` you provide.
+
+.. code-block:: yaml+jinja
+
+    # alicloud_setup.yml
+
+    - hosts: localhost
+      connection: local
+
+      tasks:
+        - name: Create a set of instances
+          community.general.ali_instance:
+             instance_type: ecs.n4.small
+             image_id: "{{ ami_id }}"
+             instance_name: "My-new-instance"
+             instance_tags:
+                 Name: NewECS
+                 Version: 0.0.1
+             count: 5
+             count_tag:
+                 Name: NewECS
+             allocate_public_ip: true
+             max_bandwidth_out: 50
+          register: create_instance
+
+In the example playbook above, data about the instances created by this playbook is saved in the variable defined by the ``register`` keyword in the task.
+
+Each Alicloud module offers a variety of parameter options. Not all options are demonstrated in the above example. See each individual module for further details and examples.
