See Your First Site Tutorial for a complete walkthrough.

Architecture

Clerk uses a distributed task queue (RQ) with specialized worker types:

• fetch - Download meeting data from city websites
• ocr - Extract text from PDFs (parallel, CPU-intensive)
• compilation - Build databases and coordinate pipeline
• extraction - Entity and vote extraction (optional, memory-intensive)
• deploy - Upload to storage/CDN

Workers can run on a single machine or distributed across multiple machines for better performance.

See Worker Architecture Guide for details.
