 Used Arduino IDE version is `1.8.3`.
 
 ## Usage
-```
-action "Build examples" {
-  uses = "Legion2/arduino-builder-action@master"
-  env = {
-    BOARD_NAME = "arduino:avr:leonardo"
-  }
-}
+See [action.yml](action.yml) for comprehensive list of parameters.
+
+Basic:
+```yaml
+name: Build examples
+on: push
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v1
+    - name: Build all example sketches
+      uses: Legion2/arduino-builder-action@v2.0.0
+      with:
+        board: "arduino:avr:leonardo"
 ```
 
 ### Arguments
-Specified arguments override any default arguments passed to arduino-builder, with the exception of the sketch parameter.
-The default arguments set all mandatory parameters.
-Use the [Environment variables](#environment-variables) to change some of the parameters.
+Specified arguments override any input parameters passed to arduino-builder, with the exception of the sketch input parameter.
+Only use arguments if the input parameters don't provide the feature you need.
+See the the [action.yml](action.yml) for comprehensive list of input parameters.
 
-### Environment variables
-* **`SKETCH_PATH`** *(optional)* : Path to a single sketch
-* **`SKETCH_DIRECTORY_PATH`** *(optional)* : Directory in which to search for sketches (default: `examples/`)
-* **`BOARD_NAME`** *(optional)* : Fully Qualified Board Name (default: `arduino:avr:uno`)
-* **`LIBRARIES_PATH`** *(optional)* : Folder containing Arduino libraries.
-Use this folder to install required 3rd-party libraries.
-Libraries SHOULD be installed by a parent action e.g. [Download GitHub Release](https://github.com/marketplace/actions/download-github-release) (default: `libraries/`)
+### Install Libraries
+Libraries SHOULD be installed by a previous step in the job in `libraries/`.
+You can use [Download GitHub Release Action](https://github.com/marketplace/actions/download-github-release) to install a library form a GitHub Release.
