+## 💻 Installation
+
+```bash
+# Clone the repository
+git clone https://github.com/yourusername/lstm-implementation.git
+
+```
+
+## 📊 Usage Example
+
+```python
+# Configure your LSTM model
+config = {
+    'input_size': 3,
+    'hidden_size': 64,
+    'num_layers': 2,
+    'output_size': 1,
+    'dropout': 0.3,
+    'bidirectional': True
+}
+
+# Create and use the model
+model = create_lstm_model(config)
+output = model(input_sequence)
+```
+
+## 🧪 Testing
+
+The implementation includes a comprehensive testing suite:
+
+```bash
+# Run the full test suite
+python lstm_test.py
+```
+
+The test suite includes:

+
+## 🔬 Technical Implementation Details
+
+### LSTM Cell Mathematics
+
+The core LSTM cell implements the following equations:
+
+```
+f_t = σ(W_f · [h_{t-1}, x_t] + b_f)    # Forget gate
+i_t = σ(W_i · [h_{t-1}, x_t] + b_i)    # Input gate
+g_t = tanh(W_g · [h_{t-1}, x_t] + b_g)  # Candidate cell state
+o_t = σ(W_o · [h_{t-1}, x_t] + b_o)    # Output gate
+
+c_t = f_t ⊙ c_{t-1} + i_t ⊙ g_t       # New cell state
+h_t = o_t ⊙ tanh(c_t)                  # New hidden state
+```
+
+### Optimizations
+
