+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+      reproduction, and distribution of the Work otherwise complies with

-# cloud-cap-samples
+# Welcome to cap/samples
 
-This is a monorepository for sample projects on [SAP Cloud Application Programming Model](https://cap.cloud.sap).
+Find here a collection of samples for the [SAP Cloud Application Programming Model](https://cap.cloud.sap) organized in a simplistic [monorepo setup](samples.md#all-in-one-monorepo). → See [**Overview** of contained samples](samples.md)
 
-## Description
+![](https://github.com/SAP-samples/cloud-cap-samples/workflows/CI/badge.svg)
 
-This repository provides a list of samples and reusable packages created based on SAP Cloud Application Programming Model.
-The SAP Cloud Application Programming Model enables you to quickly create business applications by allowing you to focus on your domain logic. It offers a consistent end-to-end programming model that includes languages, libraries and APIs tailored for full-stack development on SAP Cloud Platform.
+### Preliminaries
 
-The samples provided can be run in a local setup on SQLite Database.
+1. [Install @sap/cds-dk](https://cap.cloud.sap/docs/get-started/) as documented in [capire](https://cap.cloud.sap)
+2. _Optional:_ [Use Visual Studio Code](https://cap.cloud.sap/docs/get-started/in-vscode)
 
 
-## Requirements
-* [Node.js](https://nodejs.org/en/) v8 or higher
-* [Git](https://git-scm.com)
-* [SQLite DB](https://www.sqlite.org/download.html) (Windows only; pre-installed on Mac/Linux)
+### Download
 
-#### Optional (if you want to import the code into an editor)
-* [VS Code](https://code.visualstudio.com)
-* [Add CDS extension to VS](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/be944d6d51f343f6b3f53c29c44ff00a.html)
+Clone this repo as shown below, if you have [git](https://git-scm.com/downloads) installed,
+otherwise [download as zip file](archive/master.zip).
 
-## Download and Installation
-
-#### Install `cds` development kit
 ```sh
-# sets the registry for `@sap` packages
-npm set @sap:registry=https://npm.sap.com
-
-npm install -g @sap/cds-dk
-cds  #> test-run it
+git clone https://github.com/sap-samples/cloud-cap-samples samples
+cd samples
 ```
-Got issues?  Check out the [documentation](https://cap.cloud.sap/docs/get-started/).
 
-#### Clone and build the application
-`git clone https://github.com/SAP-samples/cloud-cap-samples samples && cd samples && npm i`
+### Setup
 
-#### Run the samples
+In the samples folder run:
 
-With that you're ready to run the samples, e.g. start the [_bookshop_](./packages/bookshop) sample as follows:
+```sh
+npm install
+```
 
-`npm run bookshop`
+### Run
 
-## Test
+With that you're ready to run the samples, for example:
 
-For example, try these links in your browser:
-- <http://localhost:4004> to test with generic index page.
-- <http://localhost:4004/fiori.html> to test with Fiori sandbox.
+```sh
+cds watch bookshop
+```
+
+After that open this link in your browser: [http://localhost:4004](http://localhost:4004)
+
+### Testing
+
+Run the provided tests with [_jest_](http://jestjs.io) or [_mocha_](http://mochajs.org), for example:
+```sh
+npx jest
+```
+> While mocha is a bit smaller and faster, jest runs tests in parallel and isolation, which allows to run all tests.

+# Bookshop Getting Started Sample
+
+This stand-alone sample introduces the essential tasks in the development of CAP-based services as also covered in the [Getting Started guide in capire](https://cap.cloud.sap/docs/get-started/in-a-nutshell).
+
+## Hypothetical Use Cases
+
+1. Build a service that allows to browse _Books_ and _Authors_.
+2. Books have assigned _Genres_ which are organized hierarchically.
+3. All users may browse books without login.
+4. All entries are maintained by Administrators.
+5. End users may order books (the actual order mgmt being out of scope)
+
+## Running the Sample
+
+```sh
+npm run watch
+```
+
+## Content & Best Practices
