 ## Overview
 
-`iec61131` is a comprehensive parser for IEC 61131-3, the international standard for PLC (Programmable Logic Controller) programming languages. It supports all 5 standardized languages:
+`iec61131` is a parser for IEC 61131-3 Structured Text (ST), the international standard for PLC (Programmable Logic Controller) programming. Currently supports:
 
-- **ST** (Structured Text) - High-level programming language
+- **ST** (Structured Text) - High-level programming language ✅
+
+**Planned support** for additional IEC 61131-3 languages:
 - **IL** (Instruction List) - Low-level assembly-like language
 - **LD** (Ladder Diagram) - Graphical ladder logic representation
 - **FBD** (Function Block Diagram) - Graphical function block representation
 - **SFC** (Sequential Function Chart) - State machine representation
 
 ## Features
 
-- ✅ **Complete IEC 61131-3:2013 support** - Based on official specification
-- ✅ **All 5 languages** - ST, IL, LD, FBD, SFC
-- ✅ **Full syntax support** - Functions, function blocks, programs, classes, interfaces
+- ✅ **Structured Text (ST) support** - Based on IEC 61131-3:2013 specification
+- ✅ **Full ST syntax support** - Functions, function blocks, programs, classes, interfaces
 - ✅ **Modern PLC features** - OOP (classes, interfaces), namespaces, references
 - ✅ **Detailed error reporting** - Source locations and helpful messages
 - ✅ **Security limits** - DoS protection with configurable resource limits
