+
+To run the application in development, you'll first need a Redis server.
+
+The easiest way is to start a local Redis instance using Docker:
+
+```sh
+docker run --name mojo-redis -p 6379:6379 -d redis
+```
+
+Install Perl dependencies with [Carton](https://github.com/perl-carton/carton):
+
+```sh
+carton install
+```
+
+Add your changes and your tests, then start the application with `morbo`:
+
+```sh
+carton exec morbo bin/urupam
+```
+
+The application will listen on port `3000` by default.
+
+## Running tests
+
+As every perl project, tests are located in the `t` directory.
+
+To run tests, use the `carton` command:
+
+```sh
+carton exec prove -lr t/
+```
+
+To run specific tests (like integration tests), use:
+
+```sh
+carton exec prove -lr t/integration.t
+```
