Project layout

As a Django newcomer I'm still confused about project layout naming
conventions. Following the author's layout in '2 Scoops' chapter 3 for a
project I'm building for my own use to manage prospects and clients, I ran
cookiecutter pointing to pydanny's cookiecutter-django. I have several
subdirectory layers with two of them having the same name, and I need
clarification for these.

My directory tree looks like this (plain ASCII text in my MUA, alpine):

clientmgmtsystem_project/
└── clientmgmtsystem
├── clientmgmtsystem
│   ├── contrib
│   │   └── sites
│   │   └── migrations
│   ├── static
│   │   ├── css
│   │   ├── fonts
│   │   ├── images
│   │   ├── js
│   │   └── sass
│   ├── templates
│   │   ├── account
│   │   ├── bootstrap4
│   │   │   └── layout
│   │   ├── pages
│   │   └── users
│   └── users
│   ├── migrations
│   └── tests
├── config
│   └── settings
├── docs
├── requirements
└── utility

Directly under the top-level directory are the clientmgmtsystem/
subdirectory which contains another subdirectory with the same name. I
assume the topmost one is the Django project name, but what is the second
one? If I want to invoke the application using 'edb' as the application
name, which directory needs to be renamed?

Looking forward to learning,
