+## Important Notes for Local Development
+
+**GoReleaser Environment Requirements**: When testing GoReleaser locally, you need to set GitHub environment variables since it's designed for CI/CD pipelines:
+
+```bash
+# For local testing of GoReleaser builds (wheel only, skip Docker):
+GITHUB_REPOSITORY_OWNER=testuser goreleaser build --snapshot --clean --skip=validate
+
+# Full GoReleaser test requires Docker and GitHub container registry access
+# This is best done in CI/CD environment or with proper GitHub credentials
+```
+
+The GoReleaser configuration is primarily designed for automated CI/CD workflows. Local testing should focus on:
+- `uv build` for Python package building
+- `docker build -t test .` for containerization (requires pre-built wheel)
+- GoReleaser snapshot builds for wheel generation testing
