 ## XTLS? Xray? V2Ray?

-- Xray-core is a superset of v2ray-core, with better overall performance and enhancements such as XTLS, and it's~~completely~~compatible with v2ray-core functionality and configuration.
+- Xray-core originally branched from v2ray-core, but it has evolved independently for a long time and should no longer be treated as a fully compatible drop-in replacement.
   - Only one executable file, including ctl functionality, run is the default command
-  - Configuration is~~completely~~compatible, environment variables and API calls need to be changed to start with XRAY\_
+  - Some configuration structures and usage patterns still resemble v2ray-core, but environment variables, API prefixes, and many features are already different
   - Exposed raw protocol's ReadV on all platforms
-  - Provides complete VLESS & Trojan XTLS support, both with ReadV
-  - Provides multiple XTLS flow control modes, unrivaled performance!
-
-> "Configuration compatible, overall better"
+  - Provides complete support for VLESS, XTLS Vision, and REALITY
+  - Provides multiple XTLS flow-control modes and can deliver extremely high performance with Splice in suitable scenarios
