-# RUST-Wipe-Bot
+# Rust Wipe Countdown Discord Webhook
 
-A bot that updates an embed with RUST server wipe countdown.
+A lightweight Python script that automatically posts or updates a Discord embed showing the **next Rust monthly wipe**, including:
+
+- A DST‑safe UK timestamp (auto‑adjusts GMT/BST)
+- A relative timestamp (`in 3 weeks`, `in 2 days`, etc.)
+- A dynamic colour indicator (green/yellow/red)
+- A 10‑segment emoji progress bar
+- A “Last updated” footer timestamp
+- Automatic create/edit mode for Discord webhooks
+
+Perfect for Rust community servers that want a clean, automated countdown updated via cron.
+
+---
+
+## How It Works
+
+The script calculates the **first Thursday of next month** — the official Rust wipe day — and sets the wipe time to **19:00 UK time**.
+
+### DST‑Safe Date Handling
+
+The script uses:
+
+- `pytz.timezone("Europe/London")`
+- `tz.localize(...)`
+- UTC conversion only when generating the UNIX timestamp
+
+This ensures the embed always shows **19:00 UK time**, even when the UK switches between GMT and BST.
+
+### Dynamic Colour Logic
+
+The embed colour changes based on how many days remain:
+
+| Days Left | Colour | Meaning |
+|----------|--------|---------|
+| > 7      | Green  | Plenty of time |
+| 3–7      | Yellow | Getting close |
+| < 3      | Red    | Imminent wipe |
+
+### Emoji Progress Bar
+
+The script calculates the time between:
+
+- **Last wipe** (previous first Thursday @ 19:00)
+- **Next wipe**
+
+Then fills a 10‑segment bar with:
+
+- 🟩 (green)
+- 🟨 (yellow)
+- 🟥 (red)
+
+depending on how close the wipe is.
+
+Example:
+🟩🟩🟩⬜⬜⬜⬜⬜⬜⬜ 30%
+
+
+### Webhook Create/Edit
+
+The script supports two modes:
+
+- `"create"` — posts a new message  
+- `"edit"` — updates an existing message using its ID  
+
+This allows you to run the script via cron without spamming your channel.
+
+---
+
+## Configuration
+
+Before running the script, update the following fields:
+
+```python
+WEBHOOK_URL = ""
+MODE = "create"
+MESSAGE_ID = ""
+```
+
+### 1. WEBHOOK_URL
+Paste your Discord webhook URL:
+```WEBHOOK_URL = "https://discord.com/api/webhooks/XXXX/XXXX"```
+
+### 2. MODE
+- First run:
+  ```MODE = "create"```
+- After the message is created, copy its ID and switch to:
+  ```MODE = "edit"```
+
+### 3. MESSAGE_ID
+Only required in edit mode.
+
+Right‑click the message → Copy Message Link → extract the ID at the end.
+
+Example:
+```https://discord.com/channels/.../1555000080555554444```
+
+So:
+```MESSAGE_ID = "1555000080555554444"```
+
+## Installation
+Install dependencies:
+```pip install requests pytz```
+
+## Running the Script
+Manual Run:
+```python updater.py```
+
+Cron Automation (Recommended)
+Example: update every hour
+```0 * * * * /usr/bin/python3 /home/pi/discord-bot/updater.py```
