+
+> are you or are you not a tty?
+
+
+## install
+
+Add the following to your `Cargo.toml`
+
+```toml
+[dependencies]
+atty = "0.2"
+```
+
+## usage
+
+```rust
+use atty::Stream;
+
+fn main() {
+  if atty::is(Stream::Stdout) {
+    println!("I'm a terminal");
+  } else {
+    println!("I'm not");
+  }
+}
+```
+
+## testing
+
+This library has been unit tested on both unix and windows platforms (via appveyor).
+
+
+A simple example program is provided in this repo to test various tty's. By default.
+
+It prints
+
+```bash
+$ cargo run --example atty
+stdout? true
+stderr? true
+stdin? true
+```
+
+To test std in, pipe some text to the program
+
+```bash
+$ echo "test" | cargo run --example atty
+stdout? true
+stderr? true
+stdin? false
+```
+
+To test std out, pipe the program to something
+
+```bash
+$ cargo run --example atty | grep std
+stdout? false
+stderr? true
+stdin? true
+```
+
+To test std err, pipe the program to something redirecting std err
+
+```bash
+$ cargo run --example atty 2>&1 | grep std
+stdout? false
+stderr? false
+stdin? true
+```
