-Work in progress
+Python-symbolic is a small project written in pure Python that allows you to perform symbolic mathematics on your computer. The focus is on readability and simplicity.
+
+## Features
+
+### Done:
+- Default type definitions
+- Expression tree implementation
+- Transformation of infix strings to expression trees
+- Visualization of expression trees
+
+### To-Do:
+- Create a type (BinOperator) for exponents
+- Implement complex numbers
+- Modify expression trees, including:
+  - Expansion of expressions (e.g., `a*(a+b)` to `a^2 + ab`)
+  - Factorization of expressions (e.g., `a^2 + 2ab + b^2` to `(a+b)^2`)
+  - Easy simplification (e.g., `sin(x)² + cos(x)²` to `1`)
+- Define calculus types:
+  - Derivative
+  - Integral
+  - Sum
+  - Product
+  - Limit
+
+
+
+Exemple of visualation of the expression tree (launch tree_visual.py to see)
