+# Development setup
+
+Libre Wedding Planner is made of two main pieces:
+
+- The backend (this repo), built with Ruby (on Rails)
+- The frontend (repo [here](https://gitea.bustikiller.com/bustikiller/wedding-planner-frontend/)), built with NextJS and React. You will need both to have the service fully working.
+
+Both repositories are expected to live have a common parent directory:
+
+```
+projects <or anything else>
+  |-> wedding-planner 
+  |-> wedding-planner-frontend 
+```
+
+## Docker compose
+
+Docker compose is the recommended way to run Libre Wedding Planner for development purposes. After downloading both repositories, `cd` to the root of `wedding-planner` and run:
+
+```bash
+docker compose build
+docker compose up
+```
+
+Several containers will be started:
+
+- backend: starts a Rails server that will act as an API.
+- workers: starts a runner of [solid queue](https://github.com/rails/solid_queue/) that takes .care of async tasks.
+- frontend: starts a NextJS application in charge of the frontend.
+- nginx: A reverse proxy that the backend and frontend under the same domain, and routes all requests to the upstream services.
+- db: A Postgres instance used by the backend service.
+
+The backend service will seed the database with fake data. It's worth noting that the Postgres container does not have a volume, so the application will be seeded every time the container is created.
+
+The backend, frontend and workers have hot-reloading enabled, so changes made to the codebase should be reflected in the application on the next request.
+
+Once all containers have started, visit http://libre-wedding-planner.app.localhost/dashboard to load the application.
+
+## Testing
+
+Unit tests can be executed with
+
+```
+bundle exec rspec
+```
