 # rust-python-linter
 
-A [Pyflakes](https://github.com/PyCQA/pyflakes)-inspired Python linter, written in Rust.
+A performance-focused, [Pyflakes](https://github.com/PyCQA/pyflakes)-inspired Python linter, written
+in Rust.
 
-Supports:
+Features:
 
-- Python 3.10
+- Python 3.10 compatibility
-- True parallelism
 - [ESLint](https://eslint.org/docs/latest/user-guide/command-line-interface#caching)-inspired
-  caching
+  cache semantics
+- [TypeScript](https://www.typescriptlang.org/docs/handbook/configuring-watch.html)
+  -inspired `--watch` semantics
 
+## Installation
+
+Available as [`rust-python-linter`](https://pypi.org/project/rust-python-linter/) on PyPI:
+
+```shell
+pip install rust-python-linter
 ```
+
+## Usage
+
+To run the linter, try any of the following:
+
+```shell
+rust_python_linter path/to/code/to/check.py
+# ...or...
+rust_python_linter path/to/code/
+# ...or...
+rust_python_linter path/to/code/*.py
+```
+
+You can also run in `--watch` mode to automatically re-run the linter on-change with, e.g.:
+
+```shell
+rust_python_linter path/to/code/ --watch
+```
+
+## Development
+
+As the name suggests, `rust-python-linter` is implemented in Rust:
+
+```shell
 cargo fmt
 cargo clippy
 cargo run resources/test/src
 ```
+
+## Deployment
+
+`rust-python-linter` is released for Python using [`maturin`](https://github.com/PyO3/maturin):
+
+```shell
+maturin publish
+```
