+# Collections Plugins Directory
+
+This directory can be used to ship various plugins inside an Ansible collection. Each plugin is placed in a folder that
+is named after the type of plugin it is in. It can also include the `module_utils` and `modules` directory that
+would contain module utils and modules respectively.
+
+Here is an example directory of the majority of plugins currently supported by Ansible:
+
+```
+└── plugins
+    ├── action
+    ├── become
+    ├── cache
+    ├── callback
+    ├── cliconf
+    ├── connection
+    ├── filter

+    ├── netconf
+    ├── shell
+    ├── strategy
+    ├── terminal
+    ├── test
+    └── vars
+```
+
+A full list of plugin types can be found at [Working With Plugins](https://docs.ansible.com/ansible-core/2.17/plugins/plugins.html).
