## Modules & Tasks

If playbooks are the instruction manual for setting up and managing your infrastructure, Ansible modules are the tools in your toolkit.

Modules are executable bits of code that operate on hosts; however, we don’t need to understand the underlying implementation to get them to work. Modules do the heavy-lifting in Ansible and abstract users from the complexity of the underlying details.

For more details see the Introduction to Modules and Module Index page in the Ansible documentation.
