# Installing Integrations

Integrations can be installed by moving the integration into the `integrations` directory on your Polarity Server. The integrations directory defaults to `/app/polarity-server/integrations`. There should be a directory for each integration.

```
/app/polarity-server/integrations
├── generic-rest/
├── virustotal/
├── google-maps/
└── crits
```

As an example, the above directory structure has four installed integrations (`generic-rest`, `virustotal`, `google-maps`, and `crits`).

{% hint style="info" %}
If you have changed the default integration directory you can check your Polarity Server configuration file `/app/polarity-server/config/config.js` and check the `integrations.path` property to find your integration installation path.
{% endhint %}

Once you have copied the integration to your integrations folder you will need to install the node modules that the integration depends on.

Navigate into the integration directory and run the command `npm install` to install all the dependencies. 

```bash
cd /app/polarity-server/integrations/generic-rest
npm install --production
```

You will notice that after the `npm install` command there will be a `node_modules` directory inside your integration directory. You also need to ensure that all files in your integration are owned by the `polarityd` user. You can do this with the following command:

```bash
chown -R polarityd:polarityd /app/polarity-server/integrations/generic-rest
```

Finally, you need to restart Polarity Server for the integration to be loaded the first time.

```bash
systemctl restart polarityd
```

{% hint style="info" %}
Note that after the first time an integration is installed you can restart the integration from the Polarity Integration user interface and do not need to restart the Polarity Server in the event that you make changes to the integration.
