Workflow Approval 2013

Hello,

First off I am new to SharePoint.

I have installed a new installation of SharePoint 2013 STD with a separate server running SQL. I have added the Workflow manager and everything seems fine but I have some questions.

What I would like to create is a Leave Request Workflow. The first Issue that I have is that I am missing "Approval - SharePoint 2010" from the list of available workflows. So many of the guides I have found online won't help because they reference this.

Here is the process I am trying to create.

1. User goes to SharePoint site and clicks on a link that takes them to a form to fill out.
2. This form asks for details about time off, start and end date, as well as any comments.
3. Once the user hits save, the information is sent to a designated user via email  to approve the time off. (A copy would also be sent to requesting user)
4. The "Approver" would then accept or reject.
5. If rejected an email would be sent to the requester notifying them.
6. If Accepted, an email would be sent to the requester notifying them as well as entering the details into a vacation calendar on the SharePoint site.

Is this possible? Can anyone offer any insight to create something like this?

Thanks!

Ryan
