+Composite actions reused across all RMS Tech Studio repos.
+
+### notify-telegram
+
+Pings a Telegram chat about a workflow outcome. Skips silently if credentials are missing.
+
+**Setup once (org-level)** — in Forgejo, go to your org → Settings → Actions → Secrets, add:
+
+- `TELEGRAM_BOT_TOKEN`
+- `TELEGRAM_CHAT_ID`
+
+These propagate to all repos under the org.
+
+**Usage in a workflow:**
+
+```yaml
+- name: Notify Telegram (success)
+  if: success()
+  uses: rmstechstudio/forgejo-actions/notify-telegram@main
+  with:
+    bot-token: ${{ secrets.TELEGRAM_BOT_TOKEN }}
+    chat-id: ${{ secrets.TELEGRAM_CHAT_ID }}
+    status: success
+    title: "RMS Ecosystem deploy"
+    message: ${{ github.event.head_commit.message }}
+
+- name: Notify Telegram (failure)
+  if: failure()
+  uses: rmstechstudio/forgejo-actions/notify-telegram@main
+  with:
+    bot-token: ${{ secrets.TELEGRAM_BOT_TOKEN }}
+    chat-id: ${{ secrets.TELEGRAM_CHAT_ID }}
+    status: failure
+    title: "RMS Ecosystem deploy"
+```
+
+**Inputs:**
+
+| Name | Required | Default | Description |
+|------|----------|---------|-------------|
+| `bot-token` | yes | — | Telegram bot token |
+| `chat-id` | yes | — | Telegram chat id |
+| `status` | yes | — | `success` or `failure` |
+| `title` | yes | — | Short label, e.g. "RMS Ecosystem deploy" |
+| `message` | no | `""` | Extra body (commit msg, error summary…) |
+| `notify-on-success` | no | `true` | Set `false` for silent crons |
