# Quick Start

You can read [A Comprehensive Guide to Verifying Private Data with zkPass](https://medium.com/@jovells.appiah/a-comprehensive-guide-to-verifying-private-data-with-zkpass-0be35afec44a) before start to integrate zkPass TransGate-JS-SDK.[ ](https://medium.com/@jovells.appiah/a-comprehensive-guide-to-verifying-private-data-with-zkpass-0be35afec44a)

### Register and Config the Project in zkPass DevHub

***

Login [**zkPass DevHub**](http://dev.zkpass.org), connect the wallet.

Create a new project, enter project information.

After "Create", a project is created with an appID.

Click on 'Add Schema' and choose the schema category.

Choose a base schema (the base schema is a default template of schema without assertions).

Config the assertions based on the requirements.

After 'Submit', a schema is created automatically with an unique schemaId for the project.&#x20;

Developers can add multiple schemas for the project.

{% hint style="info" %}
Once the schema is successfully created, it cannot be modified but can be deleted. Please carefully review before submitting.
{% endhint %}

### Integrate TransGate JS-SDK

***

&#x20; Developers can install the package using either [NPM](https://www.npmjs.com/package/@zkpass/transgate-js-sdk) or [Yarn](https://yarnpkg.com/package?name=@zkpass/transgate-js-sdk)

&#x20; **Using NPM**

```
npm install @zkpass/transgate-js-sdk
```

&#x20; **Using Yarn**

```
yarn add @zkpass/transgate-js-sdk
```

Integrate the TransGate JS-SDK with your project

```javascript
const verify = async () => {
  try {
    // The appid of the project created in dev center
    const appid = "8fb9d43c-2f24-424e-a98d-7ba34a5532f5"

    // Create the connector instance
    const connector = new TransgateConnect(appid)
    // The schema id of the project
    const schemaId = "516a720e-29a4-4307-ae7b-5aec286e446e"

    // Launch the process of verification
    // When running the TransGate SDK on a PC, if the user has not installed TransGate,
    // a QR code will pop up. The user can scan it using the TransGate App on their 
    // phone to complete verification (iOS users can directly use the system scanner)
    // or install TransGate from the Google Play Store. On mobile DApps, 
    // TransGate will automatically invoke the TransGate App.
    // If it is not installed, the user will be prompted to install it.
    const res = await connector.launch(schemaId)
    
    //If you want to bind the user's address with the proof, the `launch` function
    //also accepts a second parameter, which is the user's wallet address.
    const address = "0xD038048D1AE4c04dF2759F33BFda969999999641"
    const responseWithAddress = await connector.launch(schemaId, address)

    // verifiy the res onchain/offchain based on the requirement  
    } catch (error) {
    console.log('transgate error', error)
  }
}
```

{% hint style="info" %}
TransGate download link is <https://chromewebstore.google.com/detail/zkpass-transgate/afkoofjocpbclhnldmmaphappihehpma>
{% endhint %}

{% hint style="info" %}
Please make sure the domain of DApp matches the configuration of the project in dev center.
{% endhint %}

### Validate the result

***

After receiving the verification result(`res`in code block), developers should validate it.

You can refer to [API References](/developer-guides/js-sdk/api-references.md#instance-methods) and [Generate proof and verify the result](/developer-guides/js-sdk/generate-proof-and-verify-the-result.md) for more information.
