+# Markdown Link Checker
+
+Check links in markdown docs based on
+[`markdown-link-check`](https://github.com/tcort/markdown-link-check).
+The app in this repo has been updated to ignore 429 responses (too many
+requests).
+
+Update [config.json](./config.json) to exclude specific links from being
+checked (e.g. examples or links requiring authentication).  See
+[here](https://github.com/tcort/markdown-link-check/blob/master/README.md#config-file-format)
+for details and other options.
