 # Using HSRename with Gear Lever
 
-[Gear Lever](https://github.com/mijorus/gearlever) can manage and update the HSRename AppImage. Because releases are hosted on **Gitea** (not GitHub), use one of the options below.
+[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.
 
-## Option 1: Custom update URL (recommended to try first)
+## Important: use Forgejo, not Default
 
-Gitea uses the same release path style as GitHub:  
-`/owner/repo/releases/download/{tag}/{filename}`
+In the HSRename details screen:
 
-1. Open **Gear Lever** and add the HSRename AppImage (drag & drop or **Add**).
-2. Select the HSRename entry and open **Update** / **Custom update URL** (or the equivalent in your Gear Lever version).
-3. Try this URL pattern (with a wildcard for the tag):
-   ```
-   https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/*/HSRename.AppImage
-   ```
-4. If Gear Lever accepts it (e.g. field turns green or validates), it may use the Gitea releases page to resolve the latest tag and offer updates when you push new releases.
-5. Use **Check for updates** / **List updates** to see if it detects new versions.
+- **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.
 
-If your Gear Lever only supports GitHub-style URLs and rejects this, use Option 2.
+## Configure updates (Gear Lever 4+)
 
-## Option 2: Static URL (manual update link)
+1. Open **Gear Lever** → select **HSRename**.
+2. Set **Source** to **Forgejo**.
+3. Fill in:
 
-If the wildcard URL does not work:
+   | 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) |
 
-1. In Gear Lever, add HSRename and set **Update** to **Static URL**.
-2. Paste the **direct download URL** of the current release, for example:
-   - **v1.0.3:**  
-     `https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/v1.0.3/HSRename.AppImage`
-3. When a new version is released (e.g. v1.0.4), open the [releases page](https://git.hisora.dev/Dawnsorrow/HS-Rename/releases), open the new release, right‑click **HSRename.AppImage** → **Copy link address**, then in Gear Lever set the Static URL to that new link and run **Update**.
+4. Save, then use **Check for updates** / **List updates**.
 
-So: Gear Lever will only “see” updates if you change the Static URL to the new release’s download link when you want to update.
+If the fields validate (no error), Gear Lever queries:
 
-## Option 3: CLI (if you use Gear Lever from the terminal)
+`https://git.hisora.dev/api/v1/repos/Dawnsorrow/HS-Rename/releases/latest`
 
-After adding the AppImage in Gear Lever, you can set the update URL from the command line:
+and compares the release asset **file size** with your local AppImage.
 
-```bash
-# Set custom update URL (try the wildcard pattern)
-gearlever --set-update-url /path/to/HSRename.AppImage "https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/*/HSRename.AppImage"
+Gear Lever does **not** compare version numbers or file contents. If two releases compress to the same byte size (common with AppImages), it will say “No updates available” even when the app changed. HSRename releases from v1.0.7 onward include a small version-specific padding file so each release has a unique size.
 
-# Check for updates
-gearlever --list-updates
+To see which version you have without updating: open the AppImage mount folder `usr/share/hsrename/VERSION`, or check **X-AppImage-Version** in Gear Lever metadata after **Reload metadata**.
 
-# Apply update
-gearlever --update /path/to/HSRename.AppImage
-```
+## Direct download URL pattern
 
-Replace `/path/to/HSRename.AppImage` with the actual path where Gear Lever stores the AppImage.
-
-## Release download URL pattern
-
-For any release tag `vX.Y.Z`, the direct download URL is:
+For release tag `vX.Y.Z`:
 
 ```
 https://git.hisora.dev/Dawnsorrow/HS-Rename/releases/download/vX.Y.Z/HSRename.AppImage
 ```
 
-So when we push a new release (e.g. v1.0.4), that new tag’s URL is what Gear Lever needs (either via the wildcard in Option 1 or by pasting the new URL in Option 2).
+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**; local file size matches `releases/latest` (Gear Lever ignores version/content); or wrong Forgejo repo URL. |
+| 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. |
