 ## Project Structure
 
 The repository contains several packages and apps:
- - `tns-core-modules` - The core NativeScript TypeScript modules used to develop NativeScript apps.
- - `apps` - UI app used for manual testing and automation.
- - `e2e` - applications and *e2e* tests.
- - `tests` - Unit tests app for the `tns-core-modules`.
- - `tns-platform-declarations` - TypeScript definitions for Android and iOS native APIs.

 ## Initial Setup
 
 Clone (or fork/clone) the repo:
 
-```bash
+``` bash
 git clone https://github.com/NativeScript/NativeScript.git

-## TypeScript
-
-The following commands are commonly used to compile the `tns-core-modules`:
-```bash
-# Full tsc with type checking ~22.2s.
-tsc
-
-# Fast tsc ~11.2s.
-tsc --skipLibCheck
-
-# Fast watcher, ~4s. on save
-tsc --skipLibCheck -w
-```
-
-NOTE: transpile `tns-core-modules` only.
-
-The modules have `typescript` as a devDependency so you should also be able to use the locally installed TypeScript compiler from node_modules:
-
-```bash
-./node_modules/.bin/tsc
-```
-
-You can compile the TypeScript files in the `tns-core-modules` and `tns-platform-declarations` at once at the root of the repo:
-
-```bash
-npm run tsc
-```
