+# LSP-prolog
+
+Prolog support for Sublime's [LSP](https://packagecontrol.io/packages/LSP) package, via
+[scryer-prolog](https://github.com/mthom/scryer-prolog)'s built-in `--lsp` server.
+
+## Requirements
+
+* The [LSP](https://packagecontrol.io/packages/LSP) package.
+* A build of scryer-prolog whose `--lsp` flag runs a language server over stdio.
+  As of this writing that support only exists in a development fork; the flag is
+  not yet in released/upstream scryer-prolog builds. Make sure `scryer-prolog` is
+  on your `PATH`, or set the `command` setting below to its full path.
+* A Prolog syntax package that assigns the `source.prolog` scope to `.pl`/`.pro` files
+  (LSP-prolog itself does not ship syntax highlighting).
+
+## Installation
+
+Clone or copy this directory into your Sublime Text `Packages` folder as `LSP-prolog`,
+then restart Sublime Text.
+
+## Configuration
+
+Open `Preferences > Package Settings > LSP > Servers > LSP-prolog` to edit settings.
+
+```jsonc
+{
+    "command": ["scryer-prolog", "--lsp"],
+    "selector": "source.prolog"
+}
