 # redirection.io nginx module Docker example
 
-It is quite common to use Docker in development or production environments. As this has been requested by several of our users, we have set up a short example of a Docker stack for the redirection.io agent and nginx module.

    * [for the compiled nginx module version](./services/nginx-compiled/etc/nginx/nginx.conf#L35)

-	redirectionio_project_key PUT HERE YOUR PROJECT KEY;

-   The `project key` can be found on the "Instances" screen of your project: simply click on "Setup on your infrastructure".
