+# Emerald Legacy Launcher
+
+**The official community-driven hub for Legacy Console Edition (LCE) preservation.**
+
+Emerald Legacy Launcher is the result of a collaboration between developers who shared a common goal: moving away from bloated Electron-based launchers to create the fastest, most faithful LCE experience. Now the core project of our organization, Emerald centralizes the effort to preserve the nostalgic console experience on modern hardware

+
+# Open Source & Collaborative

+Emerald is an **Open Source** project. By unifying multiple launcher initiatives into this single repository, we ensure transparency, long-term preservation, and a faster development cycle. We welcome contributions from anyone passionate about the prime minecraft era !
