 ### Prerequisites
 
-Ruby (see .ruby-version) and PostgreSQL.
+Docker
 
 ### Local setup
 
 1. Clone the repo
+
 2. Navigate to the root directory of the project.
-3. `bundle install` to install Ruby dependencies.
-4. `rails db:create db:schema:load` to set up the database.
-5. `bin/dev` to start a local development server.
 
-Most features should work locally though for some you may need to add the appropriate credentials - see the `.env.test` for an example. You may need to set up accounts for the relevant services or contact a maintainer for the keys.
+3. Install Ruby dependencies and start the local development server.
+```shell
+docker compose build
+docker compose up
+```
+
+4. Run the database migrations and seed the database
+```shell
+docker compose exec app.local bash
+rails db:schema:load
+```
+
+The local development server will now be accessible at http://localhost:3000.
