 ## Compiling
 
-If you want to use / install the addon from source, you have to compile the `typescript` and `sass` files yourself.
-- Compile it [manual](#manual).
-- Compile it using [docker](#docker).
+Requirements:
+- `npm` installed.
+- A copy of this repository and a shell / console open in the copied directory.
 
-### Manual
+If the requirements are satisfied, you can continue with the following commands:
+```shell
+# install all dependencies
+$ npm install
 
-For compiling everything bare bones, you need [typescript](https://www.typescriptlang.org/) and [sass](https://sass-lang.com/) installed.
-- Compile typescript
-  ```
-  $ tsc -p src
-  ```
-- Compile sass (replace `<path to sass file>` with every `.sass` file in the `src` directory)
-  ```
-  $ sass --no-source-map <path to sass file>
-  ```
-The compiled output will be in the `src` directory.
-
-If you want to keep it a little cleaner, you additionally need [python3](https://www.python.org).
-- Compile everything with one line
-  ```
-  $ python3 build.py -b -c
-  ```
-The compiled output will remain in a (new created if not existing) `build` directory.
-
-### Docker
-
-For this, you need [docker](https://www.docker.com/) to be installed.
-- Build the docker image
-  ```
-  $ docker build -t stream-bypass .
-  ```
-- Compile
-  ```
-  $ docker run --rm -v build:/build stream-bypass
-  ```
-The compiled output will remain in a (new created if not existing) `build` directory.
+# build the extension source to a build/ directory
+$ npm run build
+```
