 [![Build Status](https://travis-ci.org/dod-ccpo/atst.svg?branch=master)](https://travis-ci.org/dod-ccpo/atst)
 
+## Description
+
+This is the main user-facing web application for the ATAT stack. All end-user
+requests are handled by ATST, with it making backend calls to various
+microservices when appropriate.
+
 ## Installation
 
+### Requirements
+See the [scriptz](https://github.com/dod-ccpo/scriptz) repository for the shared 
+requirements and guidelines for all ATAT applications.
+Additionally, ATST requires a redis instance for session management. Have redis 
+installed and running. By default, ATST will try to connect to a redis instance 
+running on localhost on its default port, 6379.
+
+### Cloning
+This project contains git submodules. Here is an example clone command that will 
+automatically initialize and update those modules:
+
+    git clone --recurse-submodules git@github.com:dod-ccpo/atst.git
+
+If you have an existing clone that does not yet contain the submodules, you can 
+set them up with the following command:
+
+    git submodule update --init --recursive
+
+### Setup
+This application uses Pipenv to manage Python dependencies and a virtual
+environment. Instead of the classic `requirements.txt` file, pipenv uses a 
+Pipfile and Pipfile.lock, making it more similar to other modern package managers 
+like yarn or mix.
+
+To perform the installation, run the setup script:
+
     script/setup
 
-The setup script installs pipenv, which is what this application uses to manage its dependences and virtualenv. Instead of the classic `requirements.txt` file, pipenv uses a Pipfile and Pipfile.lock, making it more similar to other modern package managers like yarn or mix.
+The setup script creates the virtual environment, and then calls script/bootstrap 
+to install all of the Python and Node dependencies.
 
 To enter the virtualenv manually (a la `source .venv/bin/activate`):
 
     pipenv shell
 
-If you want to automatically load the virtual environment whenever you enter the project directory, take a look at [direnv](https://direnv.net/).  An `.envrc` file is included in this repository.  direnv will activate and deactivate virtualenvs for you when you enter and leave the directory.
