Pony Examples README Conventions

These conventions are derived from existing ponylang examples/README.md files (postgres, redis, lori, crdt, uri, web_link). Follow them when writing or updating an examples/README.md.

Load pony-prose for how the prose reads. This skill says what an examples README holds; pony-prose says how to write it plainly.

Structure

1. Title — Always # Examples.

1. Intro paragraph (no heading) — 1-3 sentences describing what the examples are and any useful context. Standard phrasing for library examples: "Each subdirectory is a self-contained Pony program demonstrating a different part of the X library." If examples are ordered by complexity or grouped by category, state that here.

1. Example entries — One ## heading per example, using the directory name as the heading text. Optionally link to the directory: ## [example-name](example-name/).

1. Category grouping (when applicable) — If examples fall into natural categories, use ## for category headings and ### for individual examples within each category.

1. Start-here marker — When one example is clearly the simplest entry point, end its description with: "Start here if you're new to the library."

Example Descriptions

Each example gets a paragraph of 2-4 sentences covering:

• What it does: The concrete workflow in present tense, third person ("Connects to Redis, executes SET, prints the response, and closes the session.")
• What it demonstrates: The specific APIs, interfaces, or patterns exercised, named with backtick formatting (e.g., "Session.prepare() and NamedPreparedQuery")
• Key concepts: Any non-obvious behavior, design pattern, or protocol detail the example illustrates

Ordering

Choose one strategy and make it clear from the intro paragraph or the order itself:

• By complexity (simplest first) — Best when examples build on each other conceptually. State the ordering in the intro: "Ordered from simplest to most involved."
• By category — Best when examples cover distinct feature areas. Use ## categories with ### examples.
• By directory name — Acceptable when no natural ordering exists.

What to Omit

• Build instructions — Build commands belong in the project's top-level README or Makefile. Exception: if examples have a separate build target (e.g., make build-examples), a one-line note in the intro is acceptable.
• Source code snippets — The README describes what each example does; the code speaks for itself.
• Detailed setup instructions — If an example needs external services (a database, Redis server, TLS certificates), mention it briefly in that example's description. Detailed setup belongs in the example's own directory.
