+
+Easily tap into a pipeline.
+
+## Uses
+
+Some filters like `gulp-coffee` process all files. What if you want to process
+all JS and Coffee files in a single pipeline. Use `tap` to filter out `.coffee`
+files and process them through the `coffee` filter and let JavaScript files
+pass through.
+
+```js
+gulp.src("src/**/*.{coffee,js}")
+    .pipe(tap(function(file, t) {
+        if (path.extname(file.path) === '.coffee') {
+            return t.through(coffee, []);
+        }
+    }))
+    .pipe(gulp.dest('build'));
+```
+
+What if you want to change content like add a header? No need for a separate
+filter, just change the content.
+
+```js
+tap(function(file) {
+    file.contents = Buffer.concat([
+        new Buffer('HEADER'),
+        file.contents
+    ]);
+});
+```
+
+If you do not return a stream, tap forwards your changes.
