+## Gulp example
+
+An example use case for **merge-stream** is to combine parts of a task in a project's **gulpfile.js** like this:
+
+```js
+const gulp =          require('gulp');
+const htmlValidator = require('gulp-w3c-html-validator');
+const jsHint =        require('gulp-jshint');
+const mergeStream =   require('merge-stream');
+
+function lint() {
+  return mergeStream(
+    gulp.src('src/*.html')
+      .pipe(htmlValidator())
+      .pipe(htmlValidator.reporter()),
+    gulp.src('src/*.js')
+      .pipe(jsHint())
+      .pipe(jsHint.reporter())
+  );
+}
+gulp.task('lint', lint);
+```
