+# RustChain Mining Status Badge Action
+
+A reusable GitHub Action that writes a RustChain mining status badge into a README file.
+
+## Usage
+
+```yaml
+- uses: ./.github/actions/mining-status-badge
+  with:
+    wallet: my-wallet-name
+    readme-path: README.md
+    badge-style: flat-square
+```
+
+## Inputs
+
+- `wallet` (required): RustChain wallet used in `/api/badge/{wallet}`.
+- `readme-path` (default: `README.md`): Target file.
+- `badge-style` (default: `flat-square`): Shields.io badge style.
+
+## Behavior
+
+If the marker block exists, it is replaced:
+
+```md
+<!-- rustchain-mining-badge-start -->
+![RustChain Mining Status](https://img.shields.io/endpoint?...)
+<!-- rustchain-mining-badge-end -->
+```
+
+If missing, a new section `## Mining Status` is appended to the file.
