+A person represents one of the human users of your software system (e.g. actors, roles, personas, etc).

+# Software system
+
+A software system is the highest level of abstraction and describes something that delivers value to its users,
+whether they are human or not. This includes the software system you are modelling, and the other software systems
+upon which your software system depends (or vice versa).
+
+Unfortunately the term "software system" is the hardest of the C4 model abstractions to define, and this isn't helped
+by the fact that each organisation will also have their own terminology for describing the same thing, typically using
+terms such as "application", "product", "service", etc. One way to think about it is that a software system is
+something a single software development team is building, owns, has responsibility for, and can see the internal
+implementation details of. Perhaps the code for that software system resides in a single source code repository,
+and anybody on the team is entitled to modify it. In many cases, the boundary of a software system will correspond to
+the boundary of a single team. It may also be the case that everything inside the boundary of a software system is
+deployed at the same time.

+# Container
+
+Not Docker! In the C4 model, a container represents an __application__ or a __data store__. A container is something
+that needs to be running in order for the overall software system to work. In real terms, a container is something like:
+
+- __Server-side web application__: A Java EE web application running on Apache Tomcat, an ASP.NET MVC application running on Microsoft IIS, a Ruby on Rails application running on WEBrick, a Node.js application, etc.
+- __Client-side web application__: A JavaScript application running in a web browser using Angular, Backbone.JS, jQuery, etc.
+- __Client-side desktop application__: A Windows desktop application written using WPF, an OS X desktop application written using Objective-C, a cross-platform desktop application written using JavaFX, etc.
+- __Mobile app__: An Apple iOS app, an Android app, a Microsoft Windows Phone app, etc.
+- __Server-side console application__: A standalone (e.g. "public static void main") application, a batch process, etc.
+- __Serverless function__: A single serverless function (e.g. Amazon Lambda, Azure Function, etc).
+- __Database__: A schema or database in a relational database management system, document store, graph database, etc such as MySQL, Microsoft SQL Server, Oracle Database, MongoDB, Riak, Cassandra, Neo4j, etc.
+- __Blob or content store__: A blob store (e.g. Amazon S3, Microsoft Azure Blob Storage, etc) or content delivery network (e.g. Akamai, Amazon CloudFront, etc).
+- __File system__: A full local file system or a portion of a larger networked file system (e.g. SAN, NAS, etc).
+- __Shell script__: A single shell script written in Bash, etc.
