 # Code Generation Application
 
-Code Generation (CodeGen) Large Language Models (LLMs) are specialized AI models designed for the task of generating computer code. Such models undergo training with datasets that encompass repositories, specialized documentation, programming code, relevant web content, and other related data. They possess a deep understanding of various programming languages, coding patterns, and software development concepts. CodeGen LLMs are engineered to assist developers and programmers. When these LLMs are seamlessly integrated into the developer's Integrated Development Environment (IDE), they possess a comprehensive understanding of the coding context, which includes elements such as comments, function names, and variable names. This contextual awareness empowers them to provide more refined and contextually relevant coding suggestions.

Additionally Retrieval-Augmented Generation (RAG) and Agents are parts of the CodeGen example which provide an additional layer of intelligence and adaptability, ensuring that the generated code is not only relevant but also accurate, efficient, and tailored to the specific needs of the developers and programmers.

+
+#### Build the UI Gradio Image
+
+Build the frontend Gradio image via the command below:
+
+```bash
+cd GenAIExamples/CodeGen/ui
+docker build -t opea/codegen-gradio-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f docker/Dockerfile.gradio .

+
+### Building the Docker image locally
+
+Should the Docker image you seek not yet be available on Docker Hub, you can build the Docker image locally.
+In order to build the Docker image locally follow the instrustion provided below.
+
+#### Build the MegaService Docker Image
+
+To construct the Mega Service, we utilize the [GenAIComps](https://github.com/opea-project/GenAIComps.git) microservice pipeline within the `codegen.py` Python script. Build the MegaService Docker image via the command below:
+
+```bash
+git clone https://github.com/opea-project/GenAIExamples
+cd GenAIExamples/CodeGen
+docker build -t opea/codegen:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f Dockerfile .
+```
+
+#### Build the UI Gradio Image
+
+Build the frontend Gradio image via the command below:
+
+```bash
+cd GenAIExamples/CodeGen/ui
+docker build -t opea/codegen-gradio-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f docker/Dockerfile.gradio .
+```
+
+#### Dataprep Microservice with Redis
+
+Follow the instrustion provided here: [opea/dataprep](https://github.com/MSCetin37/GenAIComps/blob/main/comps/dataprep/src/README_redis.md)
+
+#### Embedding Microservice with TEI
+
+Follow the instrustion provided here: [opea/embedding](https://github.com/MSCetin37/GenAIComps/blob/main/comps/embeddings/src/README_tei.md)
+
+#### LLM text generation Microservice
+
+Follow the instrustion provided here: [opea/llm-textgen](https://github.com/MSCetin37/GenAIComps/tree/main/comps/llms/src/text-generation)
+
+#### Retriever Microservice
+
+Follow the instrustion provided here: [opea/retriever](https://github.com/MSCetin37/GenAIComps/blob/main/comps/retrievers/src/README_redis.md)
+
+#### Start Redis server

-## 🚀 Build Docker Images
-
-First of all, you need to build the Docker images locally. This step can be ignored after the Docker images published to the Docker Hub.
-
-### 1. Build the LLM Docker Image
-
-```bash
-git clone https://github.com/opea-project/GenAIComps.git
-cd GenAIComps
-docker build -t opea/llm-textgen:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f comps/llms/src/text-generation/Dockerfile .
-```
-
-### 2. Build the MegaService Docker Image
-
-To construct the Mega Service, we utilize the [GenAIComps](https://github.com/opea-project/GenAIComps.git) microservice pipeline within the `codegen.py` Python script. Build the MegaService Docker image via the command below:
-
-```bash
-git clone https://github.com/opea-project/GenAIExamples
-cd GenAIExamples/CodeGen
-docker build -t opea/codegen:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f Dockerfile .
-```
-
-### 3. Build the UI Docker Image
-
-Construct the frontend Docker image via the command below:
-
-```bash
-cd GenAIExamples/CodeGen/ui
-docker build -t opea/codegen-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f ./docker/Dockerfile .
-```
-
-### 4. Build CodeGen React UI Docker Image (Optional)
-
-Build react frontend Docker image via below command:
-
-**Export the value of the public IP address of your Xeon server to the `host_ip` environment variable**
-
-```bash
-cd GenAIExamples/CodeGen/ui
-docker build --no-cache -t opea/codegen-react-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f ./docker/Dockerfile.react .
-```
-
-Then run the command `docker images`, you will have the following Docker images:
-
-- `opea/llm-textgen:latest`
-- `opea/codegen:latest`
-- `opea/codegen-ui:latest`
-- `opea/codegen-react-ui:latest`

+# Document Summary
+
+This project provides a user interface for summarizing documents and text using a Dockerized frontend application. Users can upload files or paste text to generate summaries.
+
+## Docker
+
+### Build UI Docker Image
+
+To build the frontend Docker image, navigate to the `GenAIExamples/CodeGen/ui` directory and run the following command:
+
+```bash
+cd GenAIExamples/CodeGen/ui
+docker build -t opea/codegen-gradio-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f docker/Dockerfile.gradio .
+```
+
+This command builds the Docker image with the tag `opea/codegen-gradio-ui:latest`. It also passes the proxy settings as build arguments to ensure that the build process can access the internet if you are behind a corporate firewall.
+
+### Run UI Docker Image
+
+To run the frontend Docker image, navigate to the `GenAIExamples/CodeGen/ui/gradio` directory and execute the following commands:
+
+```bash
+cd GenAIExamples/CodeGen/ui/gradio
+
+ip_address=$(hostname -I | awk '{print $1}')
+docker run -d -p 5173:5173 --ipc=host \
+   -e http_proxy=$http_proxy \
+   -e https_proxy=$https_proxy \
+   -e no_proxy=$no_proxy \
+   -e BACKEND_SERVICE_ENDPOINT=http://$ip_address:7778/v1/codegen \
+   opea/codegen-gradio-ui:latest
+```
+
+This command runs the Docker container in interactive mode, mapping port 5173 of the host to port 5173 of the container. It also sets several environment variables, including the backend service endpoint, which is required for the frontend to communicate with the backend service.
+
+### Python
+
+To run the frontend application directly using Python, navigate to the `GenAIExamples/CodeGen/ui/gradio` directory and run the following command:
+
+```bash
+cd GenAIExamples/CodeGen/ui/gradio
+python codegen_ui_gradio.py
+```
+
+This command starts the frontend application using Python.
+
+## Additional Information
+
+### Prerequisites
+
+Ensure you have Docker installed and running on your system. Also, make sure you have the necessary proxy settings configured if you are behind a corporate firewall.
+
+### Environment Variables
+
+- `http_proxy`: Proxy setting for HTTP connections.
+- `https_proxy`: Proxy setting for HTTPS connections.
+- `no_proxy`: Comma-separated list of hosts that should be excluded from proxying.
+- `BACKEND_SERVICE_ENDPOINT`: The endpoint of the backend service that the frontend will communicate with.
+
+### Troubleshooting
+
+- Docker Build Issues: If you encounter issues while building the Docker image, ensure that your proxy settings are correctly configured and that you have internet access.
+- Docker Run Issues: If the Docker container fails to start, check the environment variables and ensure that the backend service is running and accessible.
+
+This README file provides detailed instructions and explanations for building and running the Dockerized frontend application, as well as running it directly using Python. It also highlights the key features of the project and provides additional information for troubleshooting and configuring the environment.
