+== Customizing nudging PRs
+Nudging feature is using renovate `https://docs.renovatebot.com/` to actually do the job,
+for which you can supply your own renovate config, which will be used during nudging.
+Renovate config has to be specified in ConfigMap in your namespace.
+
+.There are two possible options:
+. Create namespace wide config in ConfigMap named `namespace-wide-nudging-renovate-config` which will be used for all nudged components in your namespace,
+unless component specific config exists.
+. Create config for specific nudged component in ConfigMap named `nudging-renovate-config-<component-name>` and
+it will be used for the component in your namespace.
+
+Both ConfigMaps have the same format, can contain `config.json` or `config.js` keys, if both specified `config.json` has precedence.
+In the value of the key is js or json in the string.
+
+When you have either of ConfigMaps, your config will be used unmodified and it is user's responsibility to fix it when renovate pipeline will be failing because of it.
+
+.Examples
+`config.json: '{"platform":"gitlab","username":"red-hat-konflux",`
+
+`config.js: 'module.exports = {platform: "gitlab",\n\t\tusername: "red-hat-konflux",`
