+# Conan Package for fimdlp
+
+This directory contains the Conan package configuration for the fimdlp library.
+
+## Dependencies
+
+The package manages the following dependencies:
+
+### Build Requirements
+- **libtorch/2.4.1** - PyTorch C++ library for tensor operations
+
+### Test Requirements (when testing enabled)
+- **catch2/3.8.1** - Modern C++ testing framework
+- **arff-files** - ARFF file format support (included locally in tests/lib/Files/)
+
+## Building with Conan
+
+### 1. Install Dependencies and Build
+
+```bash
+# Install dependencies
+conan install . --output-folder=build --build=missing
+
+# Build the project
+cd build
+cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release
+cmake --build .
+```
+
+### 2. Using the Build Script
+
+```bash
+# Build release version
+./scripts/build_conan.sh
+
+# Build with tests
+./scripts/build_conan.sh --test
+```
+
+## Creating a Package
+
+### 1. Create Package Locally
+
+```bash
+conan create . --profile:build=default --profile:host=default
+```
+
+### 2. Create Package with Options
+
+```bash
+# Create with testing enabled
+conan create . -o enable_testing=True --profile:build=default --profile:host=default
+
+# Create shared library version
+conan create . -o shared=True --profile:build=default --profile:host=default
+```
+
+### 3. Using the Package Creation Script
+
+```bash
+./scripts/create_package.sh
+```
+
+## Uploading to Cimmeria
+
+### 1. Configure Remote
+
+```bash
+# Add Cimmeria remote
+conan remote add cimmeria <cimmeria-server-url>
+
+# Login to Cimmeria
+conan remote login cimmeria <username>
+```
+
+### 2. Upload Package
+
+```bash
+# Upload the package
+conan upload fimdlp/2.1.0 --remote=cimmeria --all
+
+# Or use the script (will configure remote instructions if not set up)
+./scripts/create_package.sh
+```
+

+## Package Options
+
+| Option | Values | Default | Description |
+|--------|--------|---------|-------------|
+| shared | True/False | False | Build shared library |
+| fPIC | True/False | True | Position independent code |
+| enable_testing | True/False | False | Enable test suite |
+| enable_sample | True/False | False | Build sample program |
+
+## Example Usage
+
+```cpp
+#include <fimdlp/CPPFImdlp.h>
+#include <fimdlp/Metrics.h>
+
+int main() {
+    // Create MDLP discretizer
+    CPPFImdlp discretizer;
+    
+    // Calculate entropy
+    Metrics metrics;
+    std::vector<int> labels = {0, 1, 0, 1, 1};
+    double entropy = metrics.entropy(labels);
+    
+    return 0;
+}
+```
+
+## Testing
+
+The package includes comprehensive tests that can be enabled with:
+
+```bash
+conan create . -o enable_testing=True
+```
+
+## Requirements
+
