 # treepuncher
-An hackable Minecraft client, built with aiocraft
+An hackable headless Minecraft client, built with [aiocraft](https://git.alemi.dev/aiocraft/about)
+
+### Features
+ * persistent storage
+ * configuration file
+ * pluggable plugin system
+ * event system with callbacks
+ * world processing
+
+## Quick Start
+Treepuncher is still in development and thus not available yet on PyPI, to install it fetch directly from git:
+ * `pip install "git+https://git.alemi.dev/treepuncher@v0.3.0"`
+
+Treepuncher can both be run as a pluggable CLI application or as a library, depending on how much you need to customize its behavior
+
+### as an application
+Treepuncher ships as a standalone CLI application which you can run with `python -m treepuncher`
+ * create your first addon (a simple chat logger) inside `./addons/chat_logger.py`
+```py
+from dataclasses import dataclass
+from treepuncher import Addon, ConfigObject
+from treepuncher.events import ChatEvent
+
+class ChatLogger(Addon):
+	@dataclass
+	class Options(ConfigObject):
+		prefix : str = ""
+	config : Options
+
+	def register(self):
+		@self.client.on(ChatEvent)
+		async def print_chat(event: ChatEvent):
+			print(f"{event.user} >> {event.text})
+```
+ * create a config file: `my_bot.ini`
+```ini
+[Treepuncher]
+server = your.server.com
+username = your_account_username
+client_id = your_microsoft_authenticator_client_id
+client_secret = your_microsoft_authenticator_client_secret
+code = microsoft_auth_code
+
+[ChatLogger]
+prefix = CHAT |::
+```
+ * run the treepuncher client : `python -m treepuncher my_bot`
+
+### as a library
+ * instantiate the Treepuncher object
+```py
+from treepuncher import Treepuncher
+
+client = Treepuncher(
+	"my_bot",
+	server="your.server.com",
+)
+```
+ * prepare your addons (must extend `treepuncher.Addon`) and install them
+```py
+from treepuncher import Addon
+
+class MyAddon(Addon):
+	pass
+
+addon = MyAddon()
+client.install(addon)
+```
+ * run your client
+```py
+client.run()
+```
+
+## Authentication
+Treepuncher supports both legacy Yggdrasil authentication (with options to override session and auth server) and modern Microsoft OAuth authentication. It will store the auth token inside a session file, to be able to restart without requiring credentials again.
+
+To be able to use Microsoft authentication you will need to register an Azure application (see [community](https://wiki.vg/Microsoft_Authentication_Scheme) and [microsoft](https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-register-app) docs on how to do that).
+
+This is a tedious process but can be done just once for many accounts, sadly Microsoft decided that only kids play minecraft and we developers should just suffer...
+
+**Be warned that Microsoft may limit your account if they find your activity suspicious**
+
+Once you have your `client_id` and `client_secret` use [this page](https://fantabos.co/msauth) to generate a login code: put in your `client_id` and any state and press `auth`.
+You will be brought to Microsoft login page, input your credentials, authorize your application and you will be redirected back to the `msauth` page, but now there should be a code in the `auth code` field.
+
+Put this code in your config and you're good to go!
+
+If you'd rather use classic Yggdrasil authentication, consider [ftbsc yggdrasil](https://yggdrasil.fantabos.co) ([src](https://git.fantabos.co/yggdrasil))
+
+Legacy Yggdrasil authentication supports both an hardcoded password or a pre-authorized access token
