Unable to run playbook

[iyushaw]

I created an inventory file with the ip of the desired host. I do
**ansible-playbook -i inventory tasks/main.yml**

This is the error I get.. I am using ubuntu 22.04 and my ansible version is ansible [core 2.13.4]

ERROR! 'include' is not a valid attribute for a Play

The error appears to be in '/home/pipi/Dev/CIS-Ubuntu-20.04-Ansible/tasks/main.yml': line 2, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
- include: section_1_Initial_Setup.yaml
