-1. Install [**@sap/cds-dk**](https://cap.cloud.sap/docs/get-started/) globally:
+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)
 
-   ```sh
-   npm i -g @sap/cds-dk

-When asked to log in, type `alice` as user and leave the password field blank, which is the [default user](https://cap.cloud.sap/docs/node.js/authentication#mocked).
-
 ### 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.
 
 
-### Serve `npm`
-
-We've included a simple npm registry mock, which allows you to do an `npm install @capire/<package>` locally. Use it as follows:
-
-1. Start the @capire registry:
-```sh
-npm run registry
-```
-> While running this will have `@capire:registry=http://localhost:4444` set with npmrc.
-
-2. Install one of the @capire packages wherever you like, for example:
-
-```sh
-npm add @capire/common @capire/bookshop
-```

-/** ------------------------------------------
- * This is a peg.js adaptation of the https://github.com/oasis-tcs/odata-abnf/blob/master/abnf/odata-abnf-construction-rules.txt
- * which directly constructs CQN out of parsed sources.
- *
- * NOTE:
- * In contrast to the OData ABNF source, which uses very detailedsemantic rules,
- * this adaptation uses rather generic syntactic rules only, e.g. not distinguishing
- * betwenn Collection Navigation or not knowing individual function names.
- * This is to be open to future enhancements of the OData standard, as well as
- * to improve error messages. For example a typo in a function name could be
- * reported specifically instead of throwing a generic parser error.
- *
- * See also: https://docs.microsoft.com/en-us/odata/concepts/queryoptions-overview
- * Future test cases http://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/abnf/odata-abnf-testcases.xml
- *
- * Limitations: Type, Geo functions are not supported,
- * maxdatetime, mindatetime, fractionalseconds,
- * totaloffsetminutes, date, totalseconds,
- * floor, ceiling also are not supported by CAP
- *
- * Examples:
- * Books
- * Books/201
