+
+## Setup
+
+1.  Read [Prerequisites][prereq] and [How to run a sample][run] first.
+1.  Install dependencies:
+
+    With **npm**:
+
+        npm install
+
+    With **yarn**:
+
+        yarn install
+
+[prereq]: ../README.md#prerequisites
+[run]: ../README.md#how-to-run-a-sample
+
+## Samples
+
+### Video Intelligence
+
+View the [documentation][video_0_docs] or the [source code][video_0_code].
+
+__Usage:__ `node analyze.js --help`
+
+```
+Commands:
+  faces <gcsUri>        Analyzes faces in a video stored in Google Cloud Storage using the Cloud Video Intelligence API.
+  shots <gcsUri>        Analyzes shot angles in a video stored in Google Cloud Storage using the Cloud Video
+                        Intelligence API.
+  labels-gcs <gcsUri>   Labels objects in a video stored in Google Cloud Storage using the Cloud Video Intelligence API.
+  labels-file <gcsUri>  Labels objects in a video stored locally using the Cloud Video Intelligence API.
+  safe-search <gcsUri>  Detects explicit content in a video stored in Google Cloud Storage.
+
+Options:
+  --help  Show help                                                                                            [boolean]
+
+Examples:
+  node analyze.js faces gs://demomaker/larry_sergey_ice_bucket_short.mp4
+  node analyze.js shots gs://demomaker/sushi.mp4
+  node analyze.js labels-gcs gs://demomaker/tomatoes.mp4
+  node analyze.js labels-file resources/cat.mp4
+  node analyze.js safe-search gs://demomaker/tomatoes.mp4
