+# Getting Started
+
+Welcome to your new project.
+
+It contains these folders and files, following our recommended project layout:
+
+| File or Folder   | Purpose                              |
+| ---------------- | ------------------------------------ |
+| `app/`           | will contain compiled front bundles  |
+| `app/front/`     | contains frontend app on react       |
+| `app/deployers/` | contains deployment stuff            |
+| `db/`            | your domain models and data go here  |
+| `srv/`           | your service models and code go here |
+| `test/`          | your services tests                  |
+| `package.json`   | project metadata and configuration   |
+| `mta.yaml`       | deployment config                    |
+| `readme.md`      | this getting started guide           |
+| `server.js`      | initial server set up                |
+
+## Development
+
+- Start cds service on 4004 port in watch mode:
+
+```json
+cds watch
+```
+
+- Open `app/front` folder and run next commands. This will install dependencies and run frontend src files watcher. When you will change src files your bundles in app directory will re-compiled. Now you can enjoy development:
+
+```json
+npm install
+npm run watch
+```
+
+> For better frontend development experience use below command instead of watcher. This will start frontend dev server on 3000 port. Now your bundles will be hot reloaded, this means you do not need reload the page to see changes:
+>
+> ```json
+> npm run start
+> ```
+
+## Test
+
+- Change package.json db section
+
+```json
+  "db": {
+    "kind": "sql"
+  }
+```
+
+- Run tests
+
+```json
+npm run test
+```
+
+## Deployment
+
+- Make sure you already have hana trial instance in your cockpit dashboard (SAP Cloud Platform).
+  Or if you are using hana instance - change it in mta.yaml config file from hanatrial to hana
+- Change package.json db section
+
+```json
+  "db": {
+    "kind": "hana"
+  }
+```
+
+- Authenticate to the Cloud Foundry:
+
+```json
+cf login
+```
+
+- Open `app/front` folder and run the following commands. This will create frontend production bundles in app subfolder:
+
+```json
+npm install
+npm run build:prod
+```
+
+- Clean up app/deployers/html5Deployer/resources folder from the previous frontend build
+
+- From root directory run:
+
+```json
+mbt build -t ./
+cf deploy media-store_1.0.0.mtar
+```
+
+- Now your services should be deployed with hanatrial instance and filled with initial data
+
