## What it is
A free, community-curated online guide that teaches competitive programming for USACO contests from Bronze to Platinum, with curated tutorials, problemsets, and progress tracking. The repository contains the MDX/Next.js website powering usaco.guide.

## Use cases
- prepare for USACO contests from Bronze to Platinum
- learn algorithms and data structures for competitive programming
- find curated practice problems with solutions
- track progress through a competitive programming curriculum
- get answers to USACO contest FAQs
- contribute to or improve competitive programming educational content

## When to choose
- you are a USACO contestant wanting an organized learning roadmap
- you want free, vetted tutorials and problem lists for algorithms and data structures
- you want to contribute to open-source educational content

## When to avoid
- you need a runnable library or tool rather than a website of learning material
- you need commercial-use licensed content (CC BY-NC-SA)
- you are looking for general software engineering tutorials outside competitive programming

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: education, tutorials
- platform: -
- tags: competitive-programming, usaco, codeforces, algorithms, data-structures, mdx, nextjs, problemsets, web-server, nodejs
