+
+Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as
+necessary. It's the "Command Line Interface Creation Kit". It's highly configurable but comes with sensible defaults out
+of the box.
+
+It aims to make the process of writing command line tools quick and fun while also preventing any frustration caused by
+the inability to implement an intended CLI API.
+
+Click in three points:
+
+- arbitrary nesting of commands
+- automatic help page generation
+- supports lazy loading of subcommands at runtime
+
+What does it look like? Here is an example of a simple Click program:
+
+```{eval-rst}
+.. click:example::
+
+    import click
+
+    @click.command()
+    @click.option('--count', default=1, help='Number of greetings.')
+    @click.option('--name', prompt='Your name',
+                  help='The person to greet.')
+    def hello(count, name):
+        """Simple program that greets NAME for a total of COUNT times."""
+        for x in range(count):
+            click.echo(f"Hello {name}!")
+
+    if __name__ == '__main__':
+        hello()
+
+And what it looks like when run:
+
+.. click:run::
+
+    invoke(hello, ['--count=3'], prog_name='python hello.py', input='John\n')
+
+It automatically generates nicely formatted help pages:
+
+.. click:run::
+
+    invoke(hello, ['--help'], prog_name='python hello.py')
+```
+
+You can get the library directly from PyPI::
+
+```python
+    pip install click
+```
