+
+Actions responsible to validate if the backwards compatibility (based on the git SHA differentiation).

+## :rocket: Usage
+
+An example workflow to use it:
+
+```yaml
+name: Mobile Continuous Delivery
+
+on: 
+  pull_request:
+    branches:
+      - main
+      - develop
+      - rc-*

+jobs:
+  build: 
+    runs-on: ubuntu-latest
+    outputs:
+      is_backwards_compatible: ${{ steps.backwards_compatible.outputs.is_backwards_compatible }}
+    steps:
+      - uses: actions/checkout@v2
+
+      - run: yarn install
+
+      - working_directory: ./android

+    if: needs.build.outputs.is_backwards_compatible == 'true'
