+## Developing locally
+If you want to only run the postgres container run:
+```bash
+docker compose up postgresdb -d
+```
+
+Then you can run the application using [nodemon](https://www.npmjs.com/package/nodemon). This allows you to devop in the application and it will automatically restart when you save a file.
+
+To add the config for the applciation, create a `.env` file inside the `bezkoder-app` folder with the following contents:
+
+```ini
+DB_HOST=localhost
+DB_USER=postgres
+DB_PASSWORD=123456
+DB_NAME=bezkoder_db
+DB_PORT=5433
+
+NODE_DOCKER_PORT=8080
+```
+
+Note this has the same keys as the `.env.sample` file and the same values as the `.env` file from the root of the repo.
+
+To run the application, first navigate to the application folder where `package.json` resides. e.g.
+
+```bash
+cd bezkoder-app
+```
+
+Then download the dependencies and run the application locally (provided [nodeJS](https://nodejs.org/en/download) is installed):
+
+```bash
+npm install
+npm run dev
+```
