+# Ansible Collection - jackbenny.demo
+This is a simple demonstration of what a collection looks like and works. The
+collection is made as a part of my Swedish book about Ansible.
+
+The `base` role installs some common package and sets the timezone according to
+the `timezone`-variable. The default timezone is set to Europe/Stockholm. The
+`base`-role uses the `update_cache`-role to update the package manager cache.
+
+The `dummy` module demonstrates a simple module and doesn't do anything except
+check if a value is greater than 50.
+
+## Content
+This collection contains the following:
+
+* roles
+  * base
+  * update_cache
+
+* modules
+  * dummy
+
+## Example usage
+
+```
+- hosts: ankeborg
+  become: true
+  vars:
+    timezone: Europe/Stockholm
+
+  tasks:
+    - name: Test my dummy module
+      jackbenny.demo.dummy:
+        number: 51
+      register: the_num
+    
+    - name: Print the return value
+      debug:
+        msg: "{{ the_num }}"
+
+  roles:
+    - jackbenny.demo.base
+
+```
+
+or, if your prefer to use the `collections` keyword:
+
+```
+- hosts: ankeborg
+  become: true
+  vars:
+    timezone: Europe/Stockholm
+
+  collections: 
+    - jackbenny.demo
+
+  tasks:
+    - name: Test my dummy module
+      dummy:
+        number: 51
+      register: the_num
+    
+    - name: Print the return value
+      debug:
+        msg: "{{ the_num }}"
+
+  roles:
+    - base
