# Chhoto URL Extension This extension allows for easy, shortened URL link generation using a [Chhoto URL server][chhoto-github]. ## Requirements ### Chhoto URL server In order to use this extension, a [Chhoto URL server][chhoto-github] is required. If you don't have one already, refer to the [installation instructions][install-instructions]. ### Set the `api_key` environment variable The `api_key` environment variable must be configured in the [Chhoto URL server][chhoto-github] configuration. For example, using Docker Compose, you can add the `api_key` environment variable under `environment:` like so: ```yaml environment: - api_key=SECURE_API_KEY ``` Alternatively, using Docker Run, you can add `-e api_key="SECURE_API_KEY" \` to the command arguments. **Note:** The Chhoto URL server will output a warning if this is insecure, and a generated API key will be output. You may use that value if you can't think of a secure key, or you may generate an API key using your operating system's terminal. For example, on Linux, you could generate an API key by running `tr -dc A-Za-z0-9
