+# 🔢 Binary Encoder/Decoder
+
+A simple yet powerful Python program that encodes text into binary and decodes binary back to text using 8-bit ASCII encoding. Supports alphabets, digits, punctuation, and special characters.
+
+---
+
+## 🚀 Features
+
+- ✅ Encode any text (letters, digits, symbols) into binary
+- ✅ Decode valid binary strings into readable text
+- ✅ Handles spaces and unknown characters gracefully
+- ✅ Built with beginner-friendly Python — easy to understand and extend
+
+---
+
+## 🧠 How It Works
+
+The program uses a custom dictionary (`binary_dict`) that maps characters to their **8-bit ASCII binary representation**. For decoding, it uses the reversed dictionary (`reverse_binary_dict`) to translate binary back to text.
