+title: "Usage"
+---
+
+<Note>
+  We're currently expanding the functionality of the Javascript SDK and working
+  on mirror SDKs for other languages like Python as well. Follow this GitHub
+  [issue](https://github.com/Infisical/infisical/issues/320) to stay updated.
+</Note>
+
+Infisical provides a [Node SDK](https://github.com/Infisical/infisical-node) that users can easily install into their applications and use to fetch their secrets.
+
+With the SDK, users can currently fetch back secrets and define default values.
+
+<Tabs>
+    <Tab title="Javascript">
+
+## Installation
+
+```bash
+$ npm install infisical-node
+```
+
+## Import
+
+```js
+// ES6 syntax
+import infisical from "infisical-node";
+
+// ES5 syntax
+const infisical = require("infisical-node");
+```
+
+## Initialization
+
+If your app only needs to connect to one Infisical project, you should use `infisical.connect`. If you need to connect to multiple Infisical projects, use `infisical.createConnection`.
+
+Both `connect` and `createConnection` take a parameter `token` and pull in the secrets accessible by that Infisical token.
+
+```js
+// using async-await (recommended)
+await infisical.connect({
+  token: "your_infisical_token",
+});
+```
+
+```js
+// using promise chaining
+infisical.connect({
+    token: "your_infisical_token"
+})
+.then(() => {
+    console.log('Success!)
+})
+.catch(err => {
+    console.error('Error: ', err);
+})
+```
+
+Options:
+
+| Option               | Description                                                 | Default Value               |
+| -------------------- | ----------------------------------------------------------- | --------------------------- |
+| `token`              | ❗️ An Infisical Token to be used to fetch secrets          | `None`                      |
+| `siteURL`            | Site URL of Infisical to connect to                         | `https://app.infisical.com` |
+| `attachToProcessEnv` | Whether or not to attach fetched secrets to `process.env`   | `False`                     |
+| `defaultValues`      | Default values for secrets if they aren't fetched/passed in | `{}`                        |
+
+## Access a Secret Value
+
+```js
+const dbURL = infisical.getSecretValue("DB_URL");
+```
+
+## Example with Express
+
+```js
+const express = require("express");
+const port = 3000;
+const infisical = require("infisical-node");
+
+app.get("/", (req, res) => {
+  // access value
+  const name = infisical.getSecret("NAME");
+
+  res.send(`Hello! My name is: ${name}`);
+});
+
+app.listen(port, async () => {
+  // initialize client
+  await infisical.connect({
+    token: "YOUR_INFISICAL_TOKEN",
+  });
+
+  console.log(`App listening on port ${port}`);
+});
