+### Native Build Tools
+
+Some services depend on packages that require native build tools. You _ONLY_ need to install these if you want to use a service that depends on native modules or if you want to install a development version.

 For macOS, you'll need the Xcode command line tools. To install them run the following command:

-## Clone this repository
+## Install the nodecg-io cli
+
+Install the nodecg-io cli using the following command:
 
 ```shell
-git clone https://github.com/codeoverflow-org/nodecg-io.git
+npm install -g nodecg-io-cli
 ```
 
-_Note:_ You should clone nodecg-io to somewhere outside your nodecg bundles/ directory as this repo contains many bundles in subdirectories and nodecg doesn't support nesting of the bundles in other directories. You can clone it to any other path that you wish.
+_Note:_ If you are running on linux, you may need to use `sudo` if your npm installation uses a non-writeable path (default on Ubuntu apt packages, does usually not apply to installs using [nvm](https://github.com/nvm-sh/nvm))
 
-## Install all the dependencies using `npm`
 
-```shell
-cd path/to/nodecg-io
-npm install
-npm run bootstrap
-```
+## Install nodecg-io using the nodecg-io cli
 
-## Build nodecg-io:
+With the nodecg-io cli installed you can run this command inside a nodecg installation:
 
 ```shell
-cd path/to/nodecg-io
-npm run build
+nodecg-io install
 ```
 
-## Add nodecg-io directory to the nodecg config
-
-Modify the nodecg configuration in `path/to/nodecg/cfg/nodecg.json`, here is an example config:
+You will get a prompt which asks you which version you want to install. 
 
-```json
-{
-    "bundles": {
-        "paths": ["path/to/nodecg-io", "path/to/nodecg-io/samples"]
-    }
-}
-```
+- By selecting a version you create a production install that downloads the required packages from npm and setups a npm workspace to install all dependencies. Here you can choose which services you want to install.
 
-_Note 1:_ This path should point to the root of this repository, not to a bundle inside this repo.
+- `development` clones the nodecg-io git repo and builds everything from scratch. We only recommend a dev install if you are sure that you want to contribute to nodecg-io. Here you always must install all services.
 
-_Note 2:_ The second path to the samples is only required if you want to use a sample plugin.
-
-_Note 3:_ If nodecg doesn't load nodecg-io for some reason you might want to use an absolute path here.
+For starters we recommend using the latest non-development version.
 
 ## Start nodecg
 
-Now you can use nodecg-io in your own bundle. You can find example code in [./samples/](https://github.com/codeoverflow-org/nodecg-io/tree/master/samples/).
+When starting nodecg you should see that all nodecg-io related bundles should be loaded and that you can you can now access nodecg-io in your nodecg dashboard.
+
+Now you can either install a already existing bundle that uses nodecg-io or [create a new bundle](./create_bundle.md).
