# Installing a Caplin Trader package

Caplin packages are stored locally in the `caplin-packages` directory of your workspace. To install a Caplin Package in your application, run the `yarn add` command and pass the relative path to the Caplin package you want to install.
For example, to install the Caplin Trader package `br-presenter` to the application `my-app`, run the command below from the root directory of the `my-app` application:
``````$cd ~/dev/ct5-workspace/apps/my-app$ yarn add file:../../packages-caplin/br-presenter``````
