channel.json is removed; vDiff's Package Control channel now lives
in vaclavt/sublime-chanel alongside vAI and vterm.

+## Install with Package Control
+
+vDiff is distributed through the shared channel at
+[vaclavt/sublime-chanel](https://github.com/vaclavt/sublime-chanel), not the default one. Open
+**Preferences → Package Settings → Package Control → Settings** and put the channel URL in the
+`channels` array of the right-hand (User) pane:
+
+```json
+{
+    "channels": [
+        "https://packagecontrol.io/channel_v3.json",
+        "https://raw.githubusercontent.com/vaclavt/sublime-chanel/main/channel.json"
+    ]
+}
+```
+
+Keep `https://packagecontrol.io/channel_v3.json` in the list — dropping it hides every default
+package. Then run **Package Control: Install Package** from the Command Palette and pick **vDiff**.
+Upgrades arrive through **Package Control: Upgrade Package** like any other package.
+
+## Install from source
+
+Clone or symlink the repository into the Sublime Text `Packages` directory as `vDiff`:
+
+```bash
+git clone https://github.com/vaclavt/vdiff.git \
+  "$HOME/Library/Application Support/Sublime Text/Packages/vDiff"
+```
+
+Use one method or the other, not both: an unpacked `Packages/vDiff` directory overrides the
+`vDiff.sublime-package` that Package Control installs.
+
+## Command Palette
 
 - **vDiff: Changed Files** – uncommitted changes (staged, unstaged, untracked). Arrowing through
   the list previews each file; Enter keeps it, Esc goes back to what was shown.
 - **vDiff: Recent Commits** – last N commits, then the files of the chosen commit. A key binding to
   `vdiff_commits` with `{"sha": "HEAD"}` skips the list and reviews the last commit directly.

+## The channel
+
+`repository.json` in this repository is a Package Control **repository** file: its top-level key
+is `packages`, and it describes vDiff itself — where the code lives and which releases exist.
+`"tags": true` means Package Control reads the repository's git tags, so publishing a release is
+just `git tag v1.0.1 && git push --tags`. A package whose tags are all unpushed resolves to zero
+releases, and Package Control drops it from the list without an error — if vDiff is missing from
+**Install Package**, check the tags reached GitHub.
+
+The channel itself — the `channels`-array file listing `repository.json` for vDiff and vaclavt's
+other packages — lives in [vaclavt/sublime-chanel](https://github.com/vaclavt/sublime-chanel), not
+here. Add a package there instead of in this repository.
