Conceptual Documentation

Introduction:

1. [Why use ADAL4J](https://github.com/AzureAD/azure-activedirectory-library-for-java/wiki/Why use ADAL4J?)?

2. Pre-requisite: Before using ADAL4J you will have to register you applications with Azure AD through the Azure portal (https://portal.azure). If you are not familiar with application registration, reading the following article will be valuable: Integrating applications with Azure Active Directory

3. Instantiate a AuthenticationContext : a connection to Azure AD

4. Acquire a token for a user. This returns an AuthenticationResult

5. Use an access token to call a protected Web API

6. Follow best practices for a robust enterprise ready application
