# Ledger Integration

This guide will help you connect your Ledger device to your Accumulate wallet (ACME) account. The Accumulate wallet enables you to send and receive ACME.

**Prerequisite**

* You need to have Docker installed on your system.
* You need to have Git installed.
* It works on a Linux Ubuntu OS only.
* The Accumulate CLI supports the following hardware device: Ledger Nano S plus and Ledger Nano X.

### Install the Accumulate Ledger (ACME) app on your Ledger device

**Step 1** 

Clone Ledger repo from GitHub

```
git clone https://github.com/LedgerHQ/ledger-app-builder.git
```

**Step 2**

Locate the builder folder.

```
cd ledger-app-builder
```

**Step 3**

Run the ledger builder.

```
sudo Docker build -t ledger-app-builder:latest .
```

**Step 4**

Compile the app.

```
sudo docker run --rm -ti -v "$(realpath .):/app" ledger-app-builder:latest
```

**Step 5**

Then exit the shell

```
exit
```

**Step 6**

Clone Accumulate repo from Gitlab in the ledger builder repo

```
git clone https://gitlab.com/accumulatenetwork/ledger/app-accumulate.git
```

**Step 7**

Locate the accumulate folder.

```
cd app-accumulate
```

**Step 8**

Run the below command to open the docker shell.

```
./docker-loader.sh
```

**Step 9**

Run the following command in the `app` folder.

{% hint style="info" %}
**Note:** You will need to connect the Nano s-plus to your laptop and ensure it's unlocked.
{% endhint %}

```
make
```

**Step 10**

Add the following to `ENV` by typing the following command.

```
BOLOS_SDK=/opt/nanosplus-secure-sdk make load
```

If it doesn't work, run `make clean` then rerun the **step 10** command.
