-(Documentation pending implementation)
+The Events module provides a thread and type safe signal/slot mechanism. It allows you to define custom events with any number of parameters and subscribe to them using callbacks.
+#### Basic Usage
+```cpp
+#include <seallib/event.h>
+#include <iostream>
+
+using namespace seallib;
+
+// Define an event that takes an int and a string
+Event<int, std::string> OnUserLogin;
+
+void onLogin(int id, std::string name) {
+    std::cout << "User " << name << " (ID: " << id << ") logged in!" << std::endl;
+}
+
+int main() {
+    // 1. Subscribe to the event
+    auto connection = OnUserLogin.addListener(onLogin);
+
+    // 2. Add a lambda listener
+    OnUserLogin.addListener([](int id, auto name) {
+        std::clog << "[Log] Login detected for ID: " << id << std::endl;
+    });
+
+    // 3. Trigger the event
+    OnUserLogin.run(42, "SomeUser");
+
+    // 4. Remove a listener when no longer needed
+    OnUserLogin.removeListener(connection);
+
+    return 0;
+}
+```
