+Cashu Sdk Python bindings
+
+
+**ALPHA** This library is in early development, the api will change.
+
+## Supported Nuts:
+
+Check: [https://github.com/thesimplekid/cashu-crab#implemented-nuts](https://github.com/thesimplekid/cashu-crab#implemented-nuts)
+
+## Build the package
+
+```shell
+just python
+```
+
+## Getting Started
+
+For now this is not published as a package as it is still in early development. So you will have to build it as above. In the future this will be pulished and pip can be used to install. 
+
+```python
+from cashu_sdk import Wallet, Client, Amount
+
+client = Client("https://mutinynet-cashu.thesimplekid.space")
+
+mint_keys = client.get_keys()
+
+wallet = Wallet(client, mint_keys)
+
+mint_request = wallet.request_mint(Amount.from_sat(10))
+
+print(mint_request.invoice())
+
+print(mint_request.hash())
+
+```
