+# python-readchar
+
+Library to easily read single chars and keystrokes.
+
+Born as a [python-inquirer](https://github.com/magmax/python-inquirer) requirement.
+
+
+## Installation
+
+simply install it via `pip`:
+
+```bash
+pip install readchar
+```
+
+Or download the source code from [PyPi](https://pypi.python.org/pypi/readchar).
+
+
+## Usage
+
+Simply read a character or keystroke:
+
+```python
+import readchar
+
+key = readchar.readkey()
+```
+
+React to different kinds of keypresses:
+
+```python
+from readchar import readkey, key
+
+while True:
+  k = readkey()
+  if k == "a":
+    # do stuff
+  if k == key.DOWN:
+    # do stuff
+  if k == key.ENTER:
+    break
+```
+
+
+## API
+
+There are just two methods:
+
+### `readchar() -> str`
+
+Reads one character from `stdin`, returning it as a string with length 1. Waits until a character is available.
+
+As only ASCII characters are actually a single character, you usually want to use the next function, that also handles longer keys.
+
+### `readkey() -> str`
+
+Reads the next keystroke from `stdin`, returning it as a string. Waits
+until a keystroke is available.
+
+A keystroke can be:
+
+- single characters as returned by `readchar()`. These include:
+  - character for normal keys: 'a', 'Z', '9',...
+  - special characters like 'ENTER', 'BACKSPACE', 'TAB',...
+  - combinations with 'CTRL': 'CTRL'+'A',...
+- keys that are made up of multiple characters:
+  - characters for cursors/arrows: 🡩, 🡪, 🡫, 🡨
+  - navigation keys: 'INSERT', 'HOME',...
+  - function keys: 'F1' to 'F12'
+  - combinations with 'ALT': 'ALT'+'A',...
+  - combinations with 'CTRL' and 'ALT': 'CTRL'+'ALT'+'SUPR',...
+
+> **Note**
+> 'CTRL'+'C' will not be returned by `readkey()`, but instead raise a `KeyboardInterupt`. If you what to handle it yourself, use `readchar()`.
+
+### `readchar.key` module
+
+This submodule contains a list of available keys to compare against. The constants are defined depending on your operating system, so it should be
+fully portable. If a key is listed here for your platform, `readkey()` can read it, and you can compare against it.
+
+
+## OS Support
+
+This library actively supports these operating systems:
+
+- Linux
+- Windows
+
+Some operating systems are enabled, but not actively tested or supported:
+
+- macOS
+- FreeBSD
+
+Theoretically every Unix based system should work, but they will not be actively tested. It is also required that somebody provides initial test
+results before the OS is enabled and added to the list. Feel free to open a PR for that.
+
+Thank you!
+

+You have an issue problem or found a bug? You have a great new idea or just want to fix a typo? Great :+1:. We are happy to accept your issue or pull
+request, but first, please read our [contribution guidelines](https://github.com/magmax/python-readchar/blob/master/CONTRIBUTING.md). They will also
