 /// For example, `LDA #$C8` is represented as:

-/// ```text
-/// Instruction::new(

+/// let instruction = Instruction::new(

 /// Transforms 6502 assembly code to machine code.

 /// The steps are:
 /// 1. **[Lexing][assembler::lexer::Lexer]** - converting a string into tokens
 /// 2. **[Parsing][assembler::parser::Parser]** - converting tokens into an AST
-/// 3. **[Compiling][assembler::codegen::Generator]** - converting an AST into machine code in multiple passes
-///     - Pass 1: Symbol resolution - resolving labels
-///     - Pass 2: Code generation - generating machine code
+/// 3. **[Symbol resolution][assembler::symbols]** - resolving symbols like constants and labels in the AST
+/// 4. **[Code generator][assembler::codegen]** - converting an AST into machine code
