 ## Usage
 
+### Using Models
+
+Using the celebrity face recognition model to predict the celebrity in a given picture. For list of all available models visit [our models page](https://clarifai.com/explore/models).
+
+```ts
+import { Input, Model } from "clarifai-nodejs";
+
+const input = Input.getInputFromUrl({
+  inputId: "test-image",
+  imageUrl:
+    "https://samples.clarifai.com/celebrity.jpeg",
+});
+
+const model = new Model({
+  authConfig: {
+    pat: process.env.CLARIFAI_PAT!,
+    userId: process.env.CLARIFAI_USER_ID!,
+    appId: process.env.CLARIFAI_APP_ID!
+  },
+  modelId: "celebrity-face-recognition",
+});
+
+model
+  .predict({
+    inputs: [input],
+  })
+  .then((response) => {
+    const result = response?.[0].data?.conceptsList[0].name ?? "unrecognized";
+    console.log(result);
+  })
+  .catch(console.error);
+```
+
+### Using Workflows
+
+Using a custom workflow built on [clarifai.com](https://docs.clarifai.com/portal-guide/workflows/) to analyze sentiment of a given image. For list of all available workflows visit [our workflows page](https://clarifai.com/explore/workflows)
+
+```ts
+import { Input, Workflow } from "clarifai-nodejs";
+
+const input = Input.getInputFromUrl({
+  inputId: "test-image",
+  imageUrl:
+    "https://samples.clarifai.com/celebrity.jpeg",
+});
+
+const workflow = new Workflow({
+  authConfig: {
+    pat: process.env.CLARIFAI_PAT!,
+    userId: process.env.CLARIFAI_USER_ID!,
+    appId: process.env.CLARIFAI_APP_ID!
+  },
+  workflowId: "workflow-238a93",
+});
+
+workflow
+  .predict({
+    inputs: [input],
+  })
+  .then((response) => {
+    const result =
+      response.resultsList[0].outputsList[0].data?.regionsList[0].data

+### Listing available apps in an user account
+
+On Clarifai, apps act as a central repository for models, datasets, inputs and other resources and information. Checkout how to create apps on [our portal](https://docs.clarifai.com/clarifai-basics/applications/create-an-application/).

 This library doesn't use semantic versioning. The first two version numbers (`X.Y` out of `X.Y.Z`) follow the API (backend) versioning, and whenever the API gets updated, this library follows it.
 
 The third version number (`Z` out of `X.Y.Z`) is used by this library for any independent releases of library-specific improvements and bug fixes.
