# Literature Review

According to @smith2024, documentation is essential for
project success. This aligns with earlier findings
[@johnson2023; @williams2025].

The standard approach uses markdown formatting
[see @pandocmanual, chapter 3].

Multiple citations can be grouped together
[@smith2024; @johnson2023, pp. 15-20].

# Introduction

See @fig:architecture for the system overview.
The data flow is described in @sec:dataflow.
Results are shown in @tbl:results.
The equation @eq:formula describes the relationship.

# System Architecture {#sec:architecture}

# Data Flow {#sec:dataflow}

The process follows these steps...

# Results

| Metric | Value | Unit |
|--------|-------|------|
| Speed  | 100   | ms   |
| Memory | 256   | MB   |
