## Install

Choose your favorite package manager:

<CodeGroup>
  ```bash npm theme={null}
  npm install @inco/js
  ```

  ```bash yarn theme={null}
  yarn add @inco/js
  ```

  ```bash bun theme={null}
  bun add @inco/js
  ```
</CodeGroup>

## Usage

A typical usage of `@inco/js` includes 3 steps:

1. Encrypting a value.
2. Posting the ciphertext to the contract, which will perform confidential computes on it.
3. Requesting a decryption of the result of the computation.

Next, follow the [Encryption guide](/js-sdk/encryption) for a full walkthrough of these steps.
