 Tests for ra_syntax are mostly data-driven: `test_data/parser` contains subdirectories with a bunch of `.rs`
 (test vectors) and `.txt` files with corresponding syntax trees. During testing, we check
 `.rs` against `.txt`. If the `.txt` file is missing, it is created (this is how you update
-tests). Additionally, running `cargo gen-tests` will walk the grammar module and collect
+tests). Additionally, running `cargo xtask codegen` will walk the grammar module and collect
 all `// test test_name` comments into files inside `test_data/parser/inline` directory.
