We're trying out a series at Sourcegraph doing walkthroughs and deep-dives into popular open-source projects:

1. How Caddy web server works: https://sourcegraph.com/notebooks/Tm90ZWJvb2s6MTM2Nw==

2. How TypeScript ESLint works: https://sourcegraph.com/notebooks/Tm90ZWJvb2s6MTA2OA==

The goal is to write these as if we were onboarding new contributors to the codebase. If there are maintainers of projects that'd like to be featured, please hit us up: https://discord.gg/SQCbGe6zTn. And you can subscribe here: https://tourdesource.substack.com.
