+# gcov2lcov-action
+
+[![Build Status](https://github.com/jandelgado/gcov2lcov-action/workflows/test/badge.svg)](https://github.com/jandelgado/gcov2lcov-action/actions?workflow=test)
+
+Convert golang coverage files to lcov format. Works nicely with the [coveralls
+github action](https://github.com/marketplace/actions/coveralls-github-action) and
+uses [gcov2lcov](https://github.com/jandelgado/gcov2lcov) under the hood.
+
+## Inputs
+
+### `infile`
+
+**Optional** Name of the go coverage file. Default `coverage.out`.
+
+### `outfile`
+
+**Optional** Name of the lcov file to write. Default `coverage.lcov`.
+
+### `version`
+
+**Optional** Name of the specific gcov2lcov program version. Default `latest`.
+
+### `working-directory`
+
+**Optional** Name of directory where gcov2lcov is run. Defaults to `$GITHUB_WORKSPACE`.
+
+## Outputs
+
+No outputs.
+
+## Example usage
+
+```yaml
+uses: jandelgado/gcov2lcov-action@v1
+with:
+  infile: coverage.out        # optional, default filename is `coverage.out`
+  outfile: coverage.lcov      # optional, default filename is `coverage.lcov`
+  version: v1.0.4             # optional, use specific `gcov2lcov` release version
+  working-directory: testdata # optional, change working directory
+```
+
+### Full example
+
+```yaml
+coverage:
+  runs-on: ubuntu-latest
+  steps:
+    - name: Install Go
+      if: success()
+      uses: actions/setup-go@v3
+      with:
+        go-version: 1.18
+    - name: Checkout code
+      uses: actions/checkout@v2
