Hello

The documentation [here](https://docs.ansible.com/ansible/latest/modules/yum_module.html) , specifically states

Package groups are specified as “@development-tools”

During the DO407 exam I was explicitly asked to intsall the Development Tools group. By following the documentation I did this

**ansible servera -m yum -a “name=‘@development-tools’ state=present” --become -vv**

and did not work. This resulted in me failing this task.

When I went back home I actually discovered that what works is this:

**ansible servera -m yum -a “name=‘@Development Tools’ state=present” --become -vv**

I am inclined to say that I have failed this task during the exam BECAUSE of the documentation, but before making up my mind I would like to ask for your opinion 🙂

Thank you  
Davide

In the link you mentioned I can see:

```auto
- name: install the 'Development tools' package group
  yum:
    name: "@Development tools"
    state: present

```

```auto

```

oh wow…well, my problems is also that i stopped reading at the blue box, this is why I did not read further in the examples given.

Isn’t it misleading though? In the blue-box, the Notes section it actually says:

“Package groups are specified as **“@development-tools”** and environment groups are “@^gnome-desktop-environment”. Use the “yum group list hidden ids” command to see which category of group the group you want to install falls into.”

This is why I stopped reading there…

Yeah, indeed … may be you can raise a PR to address this issue?  
It’s not very clear to me as well.  
For DO407 exam my advice is using _ansible-doc_ as much as you can 🙂
