Getting Started
Sym is a tool for creating and manipulating symbolic content. By symbolic content, we mean both mathematical expressions and other symbolic content (source code is one example). Almost anything that can be represented as a tree of symbols can potentially be content in Sym. The topics in the Getting Started section of the documentation cover installing Sym and starting to use Sym.
Installing Sym
Sym includes a Windows installer. The installation requirements and info about the install destination are listed below.

- Using Sym
  To get started using Sym, you need to understand the basics of how documents and content are created and edited.
- Documents
  Every document has two main components; the document content that you create and the libraries that define the objects and functionality available in the document. Documents will nearly always have a reference to least one library. Without any libraries loaded there would be virtually no functionality available in the document.
- Commands
  Commands are used both to construct and manipulate expressions. Typically, single-character keystrokes are used to invoke commands. For example, the "s" keystroke normally runs the Simplify command on the highlighted expression.
