 # flutter-action
 
-This action sets up a flutter environment for use in actions. It works on Linux, Windows, and macOS.
+Flutter environment for use in GitHub Actions. It works on Linux, Windows, and macOS.
 
-# Usage
+## Usage
+
+Use specific version and channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v2
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
-  with:
-    flutter-version: '1.9.1+hotfix.6'
-- run: flutter pub get
-- run: flutter test
-- run: flutter build apk
+    flutter-version: '2.8.0'
+    channel: 'stable'
+- run: flutter --version
 ```
 
 Use latest release for particular channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v2
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
-  with:
-    channel: 'stable' # or: 'dev' or 'beta'
-- run: flutter pub get
-- run: flutter test
-- run: flutter build apk
+    channel: 'stable' # or: 'beta', 'dev' or 'master'
+- run: flutter --version
 ```
 
 Use latest release for particular version and/or channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v2
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
+    flutter-version: '1.22.x' # or, you can use 1.22
+    channel: 'dev'
+- run: flutter --version
+```
+
+Use particular version on any channel:
+
+```yaml
+steps:
+- uses: actions/checkout@v2
+- uses: subosito/flutter-action@v2
   with:
-    flutter-version: '1.12.x' # you can use 1.12
-    channel: 'dev' # optional, default to: 'stable'
+    flutter-version: '2.x'
+    channel: 'any'
+- run: flutter --version
+```
+
