 ## Verification

 # PgTidy — DataGrip / JetBrains Plugin
 
-Formats and lints SQL files in DataGrip (and any JetBrains IDE) via the LSP4IJ plugin.
+Formats SQL files in DataGrip (and any JetBrains IDE) by shelling out to the `pgtidy` binary.
 
 ## Requirements
 
 - `pgtidy` binary on `PATH` — download from [releases](https://git.warky.dev/wdevs/PgTidy/releases) or build with `go install git.warky.dev/wdevs/pgtidy/cmd/pgtidy@latest`
-- [LSP4IJ](https://plugins.jetbrains.com/plugin/23257-lsp4ij) plugin installed (free, by Red Hat)
 - DataGrip 2024.3+ (or any JetBrains IDE 2024.3+)
 
 ## Install the plugin
 
-### Option A — Install from disk (`.zip`)
-
 1. Build: `./gradlew buildPlugin` (output in `build/distributions/`)
 2. In DataGrip: **Settings → Plugins → ⚙ → Install Plugin from Disk…** → select the `.zip`
 3. Restart the IDE
 
-### Option B — Install LSP4IJ and configure manually (no plugin build needed)
-
-1. Install **LSP4IJ** from the marketplace (**Settings → Plugins → Marketplace → search "LSP4IJ"**)
-2. Go to **Settings → Language Servers → + (Add)**
-3. Fill in:
-   - **Name:** `PgTidy`
-   - **Command:** `pgtidy lsp`
-4. Under **Mappings**, add file patterns: `*.sql`, `*.pgsql`
-5. Click **OK** and restart the IDE
-
 ## Features
 
-- **Formatting** — `Code → Reformat Code` (`Ctrl+Alt+L`) formats the current SQL file
-- **Diagnostics** — lint findings shown as inspections (MIG001–MIG003, COR001–003, NAM001–003)
+- **Formatting** — `Format with PgTidy` (`Ctrl+Alt+Shift+P` or right-click in the editor) formats the current SQL file via `pgtidy fmt`
+- **Version check** — `Tools → Show PgTidy Version` and the status bar widget show the installed `pgtidy` version
+- **Diagnostics** — lint findings (MIG001–MIG003, COR001–003, NAM001–003) are shown inline as editor annotations, via a native `ExternalAnnotator` that runs `pgtidy lint --json`
 - **Quick fixes** — intention actions for MIG001 (add `CONCURRENTLY`) and MIG003 (add `NOT VALID`)
 
 ## Troubleshooting
 
-**Server not starting:** Check **View → Tool Windows → LSP4IJ Consoles** for stderr output. Most common cause: `pgtidy` not found on `PATH` — update the command to the full path, e.g. `/usr/local/bin/pgtidy lsp`.
+**"Cannot start pgtidy" error:** the `pgtidy` binary isn't on `PATH` for the IDE process. Install it or restart the IDE after adding it to `PATH`.
+
+**No diagnostics showing:** diagnostics only run on files with a `.sql` or `.pgsql` extension; check `pgtidy lint --json` runs cleanly on the file from a terminal with the same `PATH` as the IDE.
