+# BitTorrent Tracker Aggregation Project
+
+[![Update Status](https://github.com/adysec/tracker/workflows/Daily%20Update%20Tracker/badge.svg)](https://github.com/adysec/tracker/actions)
+[![License](https://img.shields.io/github/license/adysec/tracker)](LICENSE)
+
+## 📖 Overview
+
+This project automatically collects, tests, and maintains high-quality BitTorrent tracker server lists.  
+Through a daily automated workflow, it aggregates tracker data from multiple open-source projects, performs connectivity tests, and provides curated lists categorized by protocol.
+
+**We provide a recommended tracker endpoint. By using load-balancing based on the full tracker list from this project, you can effectively join all trackers in this project while significantly reducing concurrent requests to individual tracker servers.**
+
+`https://tracker.adysec.com/announce`
+
+
+
+## 📋 Tracker Lists
+
+This project provides two types of tracker lists: **full** and **best**.
+
+- The **full list** contains all aggregated tracker servers from upstream open-source projects and is suitable when you want maximum coverage.
+- The **best list** is strictly filtered by connectivity tests to keep only truly available, high-quality trackers, giving you the best download experience.
+
+To support different use cases, the best list is further categorized by protocol.  
+You can select the appropriate protocol type based on what your BitTorrent client supports and your network environment.
+
+- `trackers_best.txt` is the **recommended** option.  
+  It includes high-quality trackers of all supported protocols and offers the best compatibility.
+- All lists provide both a primary and a backup download source to ensure high availability.
+
+| Type | Protocol | Description | Primary | Backup |
+|------|----------|-------------|---------|--------|
+| **Full** | All | All aggregated tracker servers (no availability filtering) | [`trackers_all.txt`](https://down.adysec.com/trackers_all.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_all.txt) |
+| **Best** | All | Connectivity-tested, high-quality trackers (recommended) | [`trackers_best.txt`](https://down.adysec.com/trackers_best.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_best.txt) |
+| **Best** | HTTP | Only available HTTP trackers | [`trackers_best_http.txt`](https://down.adysec.com/trackers_best_http.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_best_http.txt) |
+| **Best** | HTTPS | Only available HTTPS trackers | [`trackers_best_https.txt`](https://down.adysec.com/trackers_best_https.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_best_https.txt) |
+| **Best** | UDP | Only available UDP trackers | [`trackers_best_udp.txt`](https://down.adysec.com/trackers_best_udp.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_best_udp.txt) |
+| **Best** | WSS | Only available WSS trackers | [`trackers_best_wss.txt`](https://down.adysec.com/trackers_best_wss.txt) | [`GitHub`](https://raw.githubusercontent.com/adysec/tracker/main/trackers_best_wss.txt) |
+
+### ✨ Key Features
+
+- 🛡️ **Secure & Reliable** – Integrates threat intelligence and automatically filters malicious IPs
+- 🔄 **Daily Updates** – Tracker lists are refreshed every day to keep them up-to-date
+- 📊 **Protocol-Aware** – Supports HTTP, HTTPS, UDP and WSS categorized lists
+- 🚀 **High Availability** – Only retains trackers that pass connectivity checks
+- 🌐 **Multi-Source Aggregation** – Aggregates tracker resources from 10+ well-known open-source projects
+
+## 🔧 Usage
+
+### Configure in BitTorrent Clients
+
+1. **qBittorrent**  
+   *Tools → Options → BitTorrent → Automatically add these trackers to new downloads → paste the list URL*
+
+2. **Transmission**  
+   *Preferences → Trackers → Add tracker URL*
+
+3. **Other Clients**  
+   Add any of the above URLs in the tracker configuration section.
+
+### Command-Line Usage
+
+```bash
+# Get the latest recommended tracker list
+curl -s https://down.adysec.com/trackers_best.txt
+
+# Get trackers for a specific protocol (e.g., UDP)
+curl -s https://down.adysec.com/trackers_best_udp.txt
+```
+
+### 🔧 Custom Filtering
+Create a blackstr.txt file to filter specific IP addresses or domains:
+
+```bash
+# Example: filter malicious IP / domain
+echo "192.168.1.100" >> blackstr.txt
+echo "malicious-tracker.com" >> blackstr.txt
+```
+
+## 📊 Data Sources
+
+This project aggregates tracker resources from the following high-quality open-source projects:
+
+- ngosang/trackerslist
+- XIU2/TrackersListCollection
+- chenjia404/CnTrackersList
+- hezhijie0327/Trackerslist
+- DeSireFire/animeTrackerList
+
+## 💡 Motivation
+
+Many public trackers perform poorly in real-world use and severely degrade download experience.
+This project aims to automatically aggregate, test, and filter trackers to provide a truly usable, frequently updated list for both personal use and the community.
+
+By leveraging DHT and various tracker information flows, we can collect more torrent metadata (similar to BTDigg) to search and organize useful content.
+However, most public torrents are concentrated in adult content, making it difficult to find valuable resources 🐶.
+
+Any tracker naturally logs clients’ IP and port information, which has threat-intelligence value.
+For example, you can observe which countries or regions a torrent is most frequently downloaded from, or quickly estimate the location and impact scope in a data-leak incident based on connection distribution.
