 ## Usage
 
-Demo:
-```python
-import logging
-import asyncio
-
-from asyncio_taskpool.pool import TaskPool
-
-
-logging.getLogger().setLevel(logging.NOTSET)
-logging.getLogger('asyncio_taskpool').addHandler(logging.StreamHandler())
-
-
-async def work(n):
-    for i in range(n):
-        await asyncio.sleep(1)
-        print("did", i)
-
-
-async def main():
-    pool = TaskPool(work, (5,))  # initializes the pool
-    pool.start(3)  # launches work tasks 0, 1, and 2
-    await asyncio.sleep(1.5)
-    pool.start()  # launches work task 3
-    await asyncio.sleep(1.5)
-    pool.stop(2)  # cancels tasks 3 and 2
-    await pool.gather()  # awaits all tasks, then flushes the pool
-
-
-if __name__ == '__main__':
-    asyncio.run(main())
-```
