 # PureCPP
 
-**PureCPP** is the C++ backend powering the core logic of the RAG (Retrieval-Augmented Generation) system. It provides high-performance native modules that integrate seamlessly with Python via bindings.
+[![Status](https://img.shields.io/badge/status-stable-brightgreen?style=flat-square)]()
 
-## Contributing
+**PureCPP is a powerful C++ backend architecture for RAG systems.**\
+Designed for maximum performance and scalability, it integrates vector search, ONNX models, and CPU/CUDA acceleration into a seamless, Python-integrated framework.
 
-We welcome contributions to **PureCPP**!
+*This repository provides detailed guidance on how to set up the environment, configure dependencies, and build the project.*
 
-Before submitting a pull request or issue, please read our [Contribution Guide](/community/CONTRIBUTING.md).

-## Documentation
+- **[Quick Start ↗](https://docs.puredocs.org/setup)**
+- **[Contributing to PureCPP ↗](docs/CONTRIBUTING.md)**
+- **[Download Pre-trained Models ↗](./models/README.md)**
 
-For full installation and setup instructions, visit our official documentation:
+---
 
-🔗 [PureCPP Documentation](https://docs.puredocs.org/setup)
+## Environment Setup
 
-## Quick Start with PIP
+---
 
-To install the package via `pip` (for end-users):
+### First of all clone the repository
 
 ```bash
-pip install purecpp
-```
+git clone --recursive https://github.com/pureai-ecosystem/purecpp
+cd purecpp
+````
 
-## Build Options
+> [!WARNING]
+>
+> If you forgot to use `--recursive` when cloning the repository,  
+> make sure to run:
+>
+> ```bash
+> git submodule update --init --recursive
+> ```
 
-You can either **build locally** or use our **Docker environment** to ensure consistency.
+### **Docker**
 
-### Building with Docker (Recommended)
+---
 
-To simplify setup and avoid installing system-wide dependencies, use the provided Dockerfile.
+* **1. Build a Docker image from the current directory and tag it as 'purecpp_env'**
 
-#### Step 1: Build the Docker image
+  ```bash
+  docker build -t purecpp_env .
+  ```
 
-```bash
-docker build -t purecpp .
-```
+* **2. Start a Docker container named 'env' from the 'purecpp_env' image, mounting current dir to /home**
 
-#### Step 2: Start a bash shell inside the container
+  ```bash
+  docker run -it --name env -v "$PWD":/home purecpp_env
+  ```
 
-```bash
-docker run -it --rm purecpp bash
-```
+* **3. Execute the `env_config.sh`**
 
-#### Step 3: Inside the container, build the project
+  ```bash
+  chmod +x scripts/*.sh
+  ./scripts/env_config.sh
+  ```
 
-```bash
-./build
-```
+  *This script automates the setup. Installing Python essentials, LibTorch, FAISS, and configuring Conan profile*
 
-This will generate the shared object (`RagPUREAI.cpython-<python-version>*.so`) in the `build/Release/` directory.
+> [!CAUTION]
+>
+> Once you've created the container using `docker run`, ***you don't need to recreate it again.***
+> Instead, follow these two simple commands to ***reuse*** the container:
+> ```bash
+> docker start env
+> ```
+> **This command *starts an existing container* that has already been created earlier using `docker run`.**
+> ```bash
+> docker exec -it env bash
+> ```
+> **This command *attaches a terminal to the running container*, allowing you to interact with it just like you would with a regular Linux shell.**
 
-#### Step 4: Copy `.so` to your test folder
+---
 
-To test the Python bindings, copy the `.so` file to your test script directory:
+### **Local**
+
+---
+
+> Requirements
+>
+> * **Python** ≥ 3.8
+> * **CMake** ≥ 3.22
+> * **GCC/G++** ≥ 13
+
+#### 1. Installing dependencies
+
+- **Ubuntu/Debian**
+  ```bash
+  sudo apt update && \
+  sudo apt upgrade -y && \
+  sudo apt install -y \
+    build-essential wget curl \
+    ninja-build cmake libopenblas-dev \
+    libgflags-dev python3-dev libprotobuf-dev \
+    protobuf-compiler unzip libssl-dev zlib1g-dev
+  ```
+
+- **Red Hat**
+  ```bash
+  yum update && 
+  yum install -y \
+        gcc gcc-c++ make git curl wget \
+        ninja-build libffi-devel openssl-devel \
+        protobuf-devel gflags-devel zlib-devel \
+        openblas-devel unzip \
+  ```
+
+#### 2. Install Rust via rustup
 
 ```bash
-cp build/Release/RagPUREAI*.so /some-test-folder
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
 ```
+*Run rustup installer non-interactively (-y).*
 
-### Building Locally (Alternative)
+```bash
+source ~/.cargo/env
+```
 
-You may also build the project manually without Docker, if your environment satisfies the requirements.
+*This places cargo and rustc in /root/.cargo & activate Rust Environment*
 
-#### Minimum Requirements to Build Locally
+#### 3. Execute the `env_config.sh`
 
-* **Python** ≥ 3.8
-* **CMake** ≥ 3.22
-* **Conan** ≥ 2.0
-* **Rust**
-* **GCC/G++** = 13
-* **Protobuf Compiler**
+  ***In case you do not have a Docker environment available, we strongly recommend that you use a Python `venv` (virtual environment) to ensure proper isolation of dependencies and reproducibility of results.***
 
-#### Build Steps
+  - Create the virtual environment (replace 'venv' with your preferred name)
+
+    ```bash
+    python3 -m venv venv
+    ```
+
+  - Activate the virtual environment on Linux or macOS
+  
+    ```bash
+    source venv/bin/activate
+    ```
+  *This practice minimizes conflicts between global packages and project-specific requirements.*
+

+# Download Pre-trained Models
+
+## 🛠️ Hugging Face to **ONNX** Converter:
+
+These Python scripts convert Hugging Face models into the ONNX format for optimized inference.
+
+These scripts handle two primary use cases:
+1. **Feature extraction models** (e.g., `sentence-transformers`).
+2. **Token classification models** (e.g., Named Entity Recognition - NER).
+
+It automatically downloads the model and organizes the exported files in a structured subdirectory.
+
+## Requirements
+  
+ *Before running the script, make sure you have the following Python packages installed:*  
+  ```bash
+  pip install torch transformers onnx onnxruntime optimum
+  ```
+
+## Examples
+
+```bash
+python3 models/hf_model_to_onnx.py -m="dbmdz/bert-large-cased-finetuned-conll03-english" -o="bert-large-cased-finetuned-conll03-english"
+```
+
+```bash
+python3 models/hf_model_to_onnx.py -m="sentence-transformers/all-MiniLM-L6-v2" -o="sentence-transformers/all-MiniLM-L6-v2"
+```
+
+## Output
