+# Delete artifacts action
+
+Action responsible for deleting old artifacts by setting expire duration.
+
+Hopefuly this is just temporary solution till github implements this functionality natively.
+
+## Inputs
+### `expire-in`
+**Required** for how long the artifacts should be kept.
+Most of the human readable formats are supported `10 minutes`, `1hr 20mins`, `1week`.
+Take a look at [parse-duration](https://github.com/jkroso/parse-duration) for more information.
+
+
+## Outputs
+### `deleted-artifacts`
+Serialized list of deleted artifacts. Empty `[]` when nothing is deleted
+
+## Usage
+
+Run this action as cron. This won't delete artifacts of running workflows because they
+are persisted after workflow completion.
+
+```yaml
+name: 'Delete old artifacts'
+on:
+  schedule:
+    - cron: '0 * * * *' # every hour
+
+jobs:
+  delete-artifacts:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: kolpav/purge-artifacts-action@v1
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+          expire-in: 7days # Setting this to 0 will delete all artifacts
+```
+
+## Contributing
+
+There are few improvements to be made, namely
+- More delete strategies (name, size, number of occurences, regex match on name etc..)
+- Better test coverage
