codecrafters-io/build-your-own-redis

This repository holds the definition for CodeCrafters' Build Your Own Redis challenge. Redis is a well known in-memory data store that many applications use for fast caching and temporary storage, and the challenge invites a learner to build a small working version of it themselves rather than just reading about how Redis works. The README itself is very short. It states plainly that the repository contains content for the challenge and that the challenge is developed using a separate tool called course-sdk, hosted at codecrafters-io/course-sdk. Anyone who wants to add support for another programming language or submit a solution is pointed to that other repository's README for instructions, rather than finding those instructions here. Because the README does not describe the challenge stages, the grading approach, or any setup steps in detail, this repository on its own reads more like internal configuration for a larger platform than a project meant to be cloned and run directly. There is no description of what languages are supported, what the pass or fail criteria look like, or how a participant actually starts. If your goal is to take the Build Your Own Redis challenge, the practical starting point is the CodeCrafters website, where this content is presented as a guided course. If your goal is to contribute new language support or infrastructure to the challenge itself, the course-sdk repository referenced in the README is where that work happens, not this one. This repo mainly exists as a data source that other tooling reads from.
