 # Chapter 1
-Simple start and end node for basic empty script.
 
+In this chapter we aim to compile simple scripts such as:
+
+```
+return 1;
+```
+
+The first statement to be implemented in the language is the `return` statement.
+The `return` statement shall accept an argument, which must be an `expression`.
+For this chapter, the language shall only have one type of `expression` - an integer literal, as
+shown in the example above. 
+
+Here is the [complete grammar](docs/01-grammar.md) of the language for this chapter. 
+
+To implement this simple language, we will need to introduce several components and data
+structures.
+
+## Implementation Language
+
+Our implementation language is Java. We chose Java as it is widely available and understood.
+
+## Architecture
+
+We will design our parser and compiler to illustrate some key aspects of the Sea of Nodes
+Intermediate Representation: 
+
+* We will construct the intermediate representation directly as we
+parse the language. There will not be an intermediate Abstract Syntax Tree representation.
+
+* The compiler will perform a few basic local optimizations as we build the
+IR; this is a key benefit of the Sea of Nodes IR.
+
+## Data Structures
+
+Our data structures will be based upon the descriptions provided in following papers:
+
+* [From Quads to Graphs: An Intermediate Representation's Journey](http://softlib.rice.edu/pub/CRPC-TRs/reports/CRPC-TR93366-S.pdf)
+* [Combining Analyses, Combining Optimzations](https://scholarship.rice.edu/bitstream/handle/1911/96451/TR95-252.pdf)
+* [A Simple Graph-Based Intermediate Representation](https://www.oracle.com/technetwork/java/javase/tech/c2-ir95-150110.pdf)
+* [Global Code Motion Global Value Numbering](https://courses.cs.washington.edu/courses/cse501/06wi/reading/click-pldi95.pdf)
+
+Following the lead from above, we will represent our intermediate representation using an object oriented data model. Details of the
+representation follow.
