67-67: Environment variable documentation change is correct.

The README now correctly shows GITHUB_TOKEN=your_github_token. Verification confirms the codebase uses GITHUB_TOKEN as the primary environment variable across multiple API routes and libraries (app/api/github/route.js, app/api/repo-commits/[repo]/route.js, and app/lib/githubTechStack.js). The NEXT_PUBLIC_GITHUB_TOKEN is supported as an optional fallback in githubTechStack.js. The documentation change aligns with the actual implementation.

65-77: Documentation is consistent—no issues found.

The environment variable is correctly documented as GITHUB_TOKEN in README.md. The other markdown file in the repository (Contributing.md) does not reference token configuration, and no .env.example or .env.local files exist in the repository. The old variable name (NEXT_PUBLIC_GITHUB_TOKEN) is not present anywhere, so there are no mismatches for developers to encounter during setup.
