 ## Developer tasks
 
 We use `npm` to manage the dependencies and to run build tasks.
 You should run all these tasks from the `rxjs/docs_app` folder.
 Here are the most important tasks you might need to use:
 
-* `npm install` - install all the dependencies.
-* `npm run setup` - install all the dependencies and run dgeni on the docs.

-* `npm run serve-and-sync` - run both the `docs-watch` and `start` in the same console.
-* `npm run lint` - check that the doc-viewer code follows our style rules.
-* `npm test` - watch all the source files, for the doc-viewer, and run all the unit tests when any change.
-* `npm test -- --watch=false` - run all the unit tests once.
-* `npm run e2e` - run all the e2e tests for the doc-viewer.

 ## Running on Docker
 
-The docs app (rxjs.dev) can run as a docker container. 
-In order to run the docs app on docker, use the following commands (**run from the rxjs folder**):  
-* `docker build -t rxjs-docs:6.4.1 .` - building the rxjs docs app image
-* `docker run -p <host-port>:4200 rxjs-docs:6.4.1` - starting the container, listening on *<host-port>* for your choice.

 ## Guide to authoring
 
 There are two types of content in the documentation:
 
-* **API docs**: descriptions of the modules, classes, interfaces, etc that make up RxJS.
-API docs are generated directly from the source code.
-The source code is contained in TypeScript files, located in the `rxjs/src` folder.
-Each API item may have a preceding comment, which contains JSDoc style tags and content.
-The content is written in markdown.
