 If you wish to always bypass these warnings, we recommend using a conditional statement in your workflow to avoid running the Very Good Coverage action when the lcov file is empty or non-existent.

+#### Why is my input path not relative to the specified `working-directory`?
+
+[Relevant issue](https://github.com/VeryGoodOpenSource/very_good_coverage/issues/35)
+
+The input path must be absolute. The specified working directory is ignored by the input path. This is because it is [not possible](https://github.com/actions/runner/issues/467) to access the working directory from an action. In other words, Very Good Coverage always runs from the root of your repository.
+
+For example, if your working directory is `my_project` and your file is at `/my_project/coverage/lcov.info` you must do:
+
+```yaml
+jobs:
+  build:
+    defaults:
+      run:
+        working-directory: my_project/
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - name: Very Good Coverage
+        uses: VeryGoodOpenSource/very_good_coverage@v2
+        with:
