+# Argument Picker
+
+A command-line argument parser for [Mingling](https://github.com/mingling-rs/mingling), enabled by the `mingling/picker` feature.
+
+```toml
+[dependencies.mingling]
+version = "0.3.0"
+features = [
+    "picker"
+]
+```
+
+Of course, you can also use it as a standalone crate by replacing `mingling::picker` with `arg_picker`:
+
+```toml
+[dependencies]
+arg-picker = "0.1.0"
+```
+
+## Chained Argument Parser
+
+Provides a clean chained-call API for declaring arguments to parse:
+
+```rust
+use arg_picker::prelude::*;
+
+let args: Vec<&str> = vec!["--name", "Bob", "--age", "24"];
+
+let (name, age) = args
+    .pick(&arg![name: String])
+    .or(|| "Alice".to_string())
+    .pick(&arg![age: i32])
+    .or(|| 24)
+    .post(|num| num.clamp(0, 120))
+    .unwrap();
+
+assert_eq!(name, "Bob".to_string());
+assert_eq!(age, 24);
+```
+
+## Parsing Function Library
+
+Provides a pure function library `parselib` for analyzing the structure of command-line arguments.
+
+```rust
+use arg_picker::parselib::*;
+```
