+# Max warnings
+
+An error will be thrown if the total number of warnings exceeds the `max-warnings` setting.
+
+## Examples
+
+This can be set as a command-line option:
+
+``` bash
+$ sass-lint --max-warnings 50
+```
+
+In `.sass-lint.yml`:
+
+``` yaml
+options:
+  max-warnings: 50

+``` javascript
+var sassLint = require('sass-lint'),
+    config = {options: {'max-warnings': 50}};
+
+results = sassLint.lintFiles('sass/**/*.scss', config)
+sassLint.failOnError(results, config);
