+# Using HSRename with Gear Lever
+
+[Gear Lever](https://github.com/mijorus/gearlever) 4.x can update HSRename from Gitea releases. Gitea uses the same API as **Forgejo**, which Gear Lever supports directly.
+
+## Important: use Forgejo, not Default
+
+In the HSRename details screen:
+
+- **Source** must be **Forgejo** (not `Default`).
+- The **Website** field is only metadata. It does **not** check for updates.
+- Do **not** paste the release download URL into Website.
+
+## Configure updates (Gear Lever 4+)
+
+1. Open **Gear Lever** → select **HSRename**.
+2. Set **Source** to **Forgejo**.
+3. Fill in:
+
+   | Field | Value |
+   |-------|--------|
+   | **Repo URL** | `https://git.hisora.dev/Dawnsorrow/HS-Rename` |
+   | **Release file name** | `HSRename.AppImage` |
+   | **Allow pre-releases** | Off (unless you want draft releases) |
+
+4. Save, then use **Check for updates** / **List updates**.
+
+If the fields validate (no error), Gear Lever queries:
+
+`https://git.hisora.dev/api/v1/repos/Dawnsorrow/HS-Rename/releases/latest`
+
+and compares the release asset size with your local AppImage.
+
+## Direct download URL pattern
+
+For release tag `vX.Y.Z`:
+
+```
+https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/vX.Y.Z/HSRename.AppImage
+```
+
+Latest release today:
+
+```
+https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/v1.0.3/HSRename.AppImage
+```
+
+## Fallback: Static URL
+
+If Forgejo does not work in your Gear Lever build, set **Source** to **Static URL** and paste the **exact** URL of the newest release (update this manually each release):
+
+```
+https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/v1.0.3/HSRename.AppImage
+```
+
+## CLI (if `gearlever` is installed)
+
+Gear Lever 4 may use different CLI options than older docs. Prefer the GUI Forgejo fields above. If your install still supports `--set-update-url`, the old wildcard pattern is **not** reliable for self-hosted Gitea; use Forgejo instead.
+
+## Troubleshooting
+
+| Symptom | Likely cause |
+|---------|----------------|
+| No update offered | Source is still **Default**, or local file is already the latest release (same size as `releases/latest`). |
+| URL looks truncated in Website | Website is cosmetic only; configure **Forgejo** fields instead. |
+| Update never finds newer builds | Wrong repo URL, wrong filename, or release has no `HSRename.AppImage` asset attached. |
