+# LeMA : Matrices simply
+
+LeMA (short for "Leto Matrix") is a lightweight C++ header-only library designed to simplify matrix manipulation.
+LeMA will eventually be used for graphical and machine learning usage in my other projects.
+
+## Features
+
+- **Lightweight**: Just a single header file.
+- **Easy to Use**: Intuitive functions.
+- **Somewhat complete**: Supports addition, subtraction, multiplication, and more.
+- **Ready to Integrate**: Designed to work seamlessly with C++ code.
+
+## Getting Started
+
+### Installation
+
+1. Clone or download the repository.
+   ```bash
+   git clone https://git.letonet.fr/gitea_admin/lema.git
+   ```
+
+2. Include the `lema.h` file in your project.
+   ```cpp
+   #include "lema.h"
+   ```
+
+That's it! You're ready to use Lema.
+
+### Example Usage
+
+#### Creating a Matrix
+
+```cpp
+#include "lema.h"
+#include <iostream>
+
+int main() {
+    Matrix mat(3, 2); // Create a 3 rows, 2 columns matrix
+    mat.Print("Weights"); // LeMA can print matrices in terminal for easy debugging
+    return 0;
+}
+```
+
+#### Matrix Addition
+
+```cpp
+#include "lema.h"
+#include <iostream>
+
+int main() {
+    Matrix a(2,2);
+    Matrix b(2,2);
+
+    a.Set(2.0F); // Fill both matrices
+    b.Set(3.0F);
+
+    a.Add(&b);
+
+    a.Print("A + B");
+    return 0;
+}
+```
+
+#### Matrix Multiplication
+
+```cpp
+#include "lema.h"
+#include <iostream>
+
+int main() {
+    Lema::Matrix<int> mat1(2, 2, {1, 2, 3, 4});
+    Lema::Matrix<int> mat2(2, 2, {1, 0, 0, 1});
+
+    auto result = mat1 * mat2;
+
+    std::cout << "Result of multiplication:\n";
+    result.print();
+    return 0;
+}
+```
