-# SnekBot: Your Instant Chat Companion
+# Snekbot API
 
-## Create Your Own Bot in Minutes
+This is the Snekbot API. This document describes how to create a bot responding to "hello", "bye" and "@username-of-bot".
 
-### Overview
-SnekBot is designed for rapid deployment and customization, providing a fully asynchronous and production-ready chat bot solution. It is built to handle network issues effectively, ensuring a reliable user experience.
+## 5 minute tutorial
 
-### Prerequisites
-- Python 3.8 or higher
-- Basic understanding of Python programming
+Literally.
 
-### Installation Instructions
+### Installation
+#### Requirements:
+Python:
+ - python3
+ - python3-venv 
+ - python3-pip
+Use apt or your package manager to install these packages. There is a big chance your system already has them.
 
-#### 1. Prepare Your Environment
-```bash
-# For Ubuntu/Debian users:
-sudo apt install python3 python3-venv python3-pip -y
+For Debian (Ubuntu): `sudo apt install python3 python3-venv python3-pip -y`
 
-# Create a virtual environment for your bot
-python3 -m venv venv
-source venv/bin/activate
-```
+#### Environment
+ - `python3 -m venv venv`
+ - `source venv/bin/activate`
+ - `pip install git+https://molodetz.nl/retoor/snekbot.git`
 
-#### 2. Install SnekBot
-```bash
-pip install git+https://molodetz.nl/retoor/snekbot.git
-```
+#### Create account
+Create regular user account for your bot. You need this later in your script.
+Make sure you have this information right now:
+ - bot username 
+ - bot password 
+ - bot url (wss://your-snek-instance.com/rpc.ws)
 
-### Bot Development
-To create your bot, use the following template:
+#### Create a file 
+Open a file ending with the `.py` extension and paste this content. Replace the authentication details on the bottom lines with the one of the account you just created. 
 
 ```python
 import asyncio

+
+
+bot = ExampleBot(
+    url="ws://snek.molodetz.nl/rpc.ws", username="example", password="example"
 )
 asyncio.run(bot.run())
 ```
 
-### Running Your Bot
+#### Run the bot
+Make sure you have (still) activated your virtual env.
 ```bash
-python your_bot_script.py
+python [your-script].py
 ```
+If you get the error 'python not found' or 'aiohttp not found', run `source .venv/bin/activate` again and run `python [your script].py` again. 
 
-### Event Handlers
-You can override the following event handlers:
-- `on_join`: Triggered when the bot joins a channel
-- `on_leave`: Triggered when the bot leaves a channel
-- `on_ping`: Responds to ping messages
-- `on_mention`: Handles direct mentions
-- `on_message`: Processes incoming messages
+#### Debugging
+Add `import logging` and `logging.BasicConfig(level=logging.DEBUG)`.
 
-### Additional Information
-- For detailed logging, include `logging.basicConfig(level=logging.DEBUG)` in your code.
-- The bot is designed to automatically reconnect in case of connection drops.
-- Feel free to customize the bot to meet your specific requirements.
+#### Summary
+The `ExampleBot` class inherits from a base `Bot` class and implements several event handlers:
+ - `on_join`: Sends a welcome message when the bot joins a channel.
+ - `on_leave`: Sends a goodbye message when the bot leaves.
+ - `on_ping`: Responds with "pong" when it receives a ping message.
+ - `on_own_message`: Logs messages sent by the bot itself.
+ - `on_mention`: Handles mentions; if "source" is in the message, it replies with its own source code, with sensitive data disguised.
+ - `on_message`: Responds to "hello" and "bye" messages if the bot has joined the channel.
+The bot will be instantiated and runs asynchronously. It will survive server deploys and network outages. If such issue occurs, it will try to reconnect within a second like nothing happened. It's production ready.
