+# tree-sitter-pony
+
+This crate provides a Pony grammar for the [tree-sitter][] parsing library. To
+use this crate, add it to the `[dependencies]` section of your `Cargo.toml`
+file. (Note that you will probably also need to depend on the
+[`tree-sitter`][tree-sitter crate] crate to use the parsed result in any useful
+way.)
+
+```toml
+[dependencies]
+tree-sitter = "~0.20.9"
+tree-sitter-pony = "0.0.1"
+```
+
+Typically, you will use the [language][language func] function to add this
+grammar to a tree-sitter [Parser][], and then use the parser to parse some code:
+
+```rust
+let code = r#"
+actor Main
+  new create(env: Env) =>
+    None
+"#;
+let mut parser = Parser::new();
+parser.set_language(tree_sitter_pony::language()).expect("Error loading Pony grammar");
+let parsed = parser.parse(code, None);
+```
+
+If you have any questions, please reach out to us in the [tree-sitter
+discussions] page.
