-# Cow Web Services
+# BFF (Backend For Frontend)
+
+Backend for frontend is a series of backend services and libraries that enhance user experience for the frontend. 
+
+## Getting Started
+
+Install dependencies:
+
+```bash
+yarn
+```
+
+Create the `.env` file:
+
+```bash
+# If you are not using docker
+cp .env.example .env
+
+# If you are using docker (handy to launch a service directly using NX)
+cp .env.example .env.docker
+```
+
+Start docker:
+```bash
+yarn compose:up
+```
+
+# Develop
+## Notification Producer
+Make sure your `.env` file is defined, if not create one using `.env.example` as a template.
+
+```bash
+# Start RabbitMQ
+docker-compose up -d queue
+
+# Start the notification producer
+yarn producer
+```
+## Create a new service or library
+
+To add a new app or library, you can run the following command;
+
+```bash
+# New API
+yarn new:fastify
+
+# New Library
+yarn new:lib
+
+# New Node app
+yarn new:node
+```
+
+For APIs and apps, it will create a Dockerfile. Please, remember to update:
+- The `docker-compose.yml` file to include the new service.
+- The github actions to include the new service (`.github/workflows/ci.yml`)
+
+For more info, see:
+- [@nx/node:application](https://nx.dev/packages/node/generators/application): Generator for Applications
+- [@nx/node:application (Fastify)](https://nx.dev/showcase/example-repos/add-fastify): Generator for API Applications using Fastify 
+- [@nx/node:setup-docker](https://nx.dev/nx-api/node/generators/library): Generator for NodeJS Libraries
+- [@nx/node:setup-docker](https://nx.dev/nx-api/node/generators/setup-docker): Docker Generator
+
+
+# Build
+## Docker
+
+Build docker containers and publish to a local registry:
+
+```bash
+yarn docker-build:affected
+```
 
-Collection of typescript based services, mainly for the use of CoW Swap.
