# Prerequisites
> Before using the library, you need to have a Nebuly Public key.
To find your available Public keys or create a new one, you need to go to Settings > Projects and click on the "View Nebuly keys" button in the row for the project you want to use.
Once you click on the button, a sheet will open with the list of your Public and Secret keys and a button to create a new one.
**Important Security Notice**: Always use your **Public key** when integrating the Nebuly library into your application. Never use your Secret key in client-side code, as this would expose it to users and create a security vulnerability. For safety reasons, the Nebuly client will not work with Secret keys and will throw an error if you attempt to use one.
Once you have the Public key, you can use the library in your project to embed the charts created in that project into your application.
