+# Making This Go Repository Private
+
+Notes on what changes when converting this public GitHub repo to private.
+
+## CI/CD - No Changes Required
+
+GitHub Actions workflows continue to work because:
+- `actions/checkout@v4` uses the built-in `GITHUB_TOKEN` which has access to its own repo
+- No external private dependencies are required
+
+## Local Development
+
+### Configure Go for Private Repos
+
+Tell Go to bypass the public module proxy:
+
+```bash
+go env -w GOPRIVATE=github.com/yourusername/go-jdenticon
+```
+
+### Git Authentication
+
+Ensure one of these is configured:
+- SSH key linked to your GitHub account
+- Personal Access Token (PAT) in git credential helper
+- `~/.netrc` file with GitHub credentials
+
+## Using as a Dependency in Other Projects
+
+Any project that imports this module needs:
+
+1. Set `GOPRIVATE`:
+   ```bash
+   go env -w GOPRIVATE=github.com/yourusername/go-jdenticon
+   ```
+
+2. Configure git authentication (see above)
+
+3. For CI in other repos, add to workflow:
+   ```yaml
+   - name: Configure git for private modules
+     run: git config --global url."https://${{ secrets.GH_PAT }}@github.com/".insteadOf "https://github.com/"
+   ```
+   (Requires a `GH_PAT` secret with `repo` scope)
+
+## What Breaks
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| pkg.go.dev documentation | Unavailable | Public proxy can't access private repos |
+| "Go Reference" badges | Broken | Remove from README or accept 404 |
+| Codecov | May need token | Add `CODECOV_TOKEN` secret if uploads fail |
+| Anonymous `go get` | Blocked | Users need authentication |
+
+## Codecov Fix (If Needed)
+
+If coverage uploads fail after going private:
+
+1. Get token from codecov.io for the repo
+2. Add as repository secret: `CODECOV_TOKEN`
+3. Update `.github/workflows/ci.yml`:
+   ```yaml
+   - name: Upload coverage to Codecov
+     uses: codecov/codecov-action@v4
+     with:
+       file: ./coverage.txt
+       token: ${{ secrets.CODECOV_TOKEN }}  # Add this line
+       flags: unittests
+       name: codecov-umbrella
+       fail_ci_if_error: false
+   ```
+
+## Reverting to Public
+
+Simply change the repository visibility back to public in GitHub settings. No code changes required.
