 # How to Contribute to Perplexica
 
-Hey there, thanks for deciding to contribute to Perplexica. Anything you help with will support the development of Perplexica and will make it better. Let's walk you through the key aspects to ensure your contributions are effective and in harmony with the project's setup.
+Thanks for your interest in contributing to Perplexica! Your help makes this project better. This guide explains how to contribute effectively.
+
+Perplexica is a modern AI chat application with advanced search capabilities.
 
 ## Project Structure
 
-Perplexica's design consists of two main domains:
+Perplexica's codebase is organized as follows:
 
-- **Frontend (`ui` directory)**: This is a Next.js application holding all user interface components. It's a self-contained environment that manages everything the user interacts with.
-- **Backend (root and `src` directory)**: The backend logic is situated in the `src` folder, but the root directory holds the main `package.json` for backend dependency management.
-  - All of the focus modes are created using the Meta Search Agent class present in `src/search/metaSearchAgent.ts`. The main logic behind Perplexica lies there.
+- **UI Components and Pages**:
+  - **Components (`src/components`)**: Reusable UI components.
+  - **Pages and Routes (`src/app`)**: Next.js app directory structure with page components.
+    - Main app routes include: home (`/`), chat (`/c`), discover (`/discover`), library (`/library`), and settings (`/settings`).
+  - **API Routes (`src/app/api`)**: API endpoints implemented with Next.js API routes.
+    - `/api/chat`: Handles chat interactions.
+    - `/api/search`: Provides direct access to Perplexica's search capabilities.
+    - Other endpoints for models, files, and suggestions.
+- **Backend Logic (`src/lib`)**: Contains all the backend functionality including search, database, and API logic.
+  - The search functionality is present inside `src/lib/search` directory.
+  - All of the focus modes are implemented using the Meta Search Agent class in `src/lib/search/metaSearchAgent.ts`.
+  - Database functionality is in `src/lib/db`.
+  - Chat model and embedding model providers are managed in `src/lib/providers`.
+  - Prompt templates and LLM chain definitions are in `src/lib/prompts` and `src/lib/chains` respectively.
+
+## API Documentation
+
+Perplexica exposes several API endpoints for programmatic access, including:
+
+- **Search API**: Access Perplexica's advanced search capabilities directly via the `/api/search` endpoint. For detailed documentation, see `docs/api/search.md`.
 
 ## Setting Up Your Environment
 
 Before diving into coding, setting up your local environment is key. Here's what you need to do:
 
-### Backend
-
 1. In the root directory, locate the `sample.config.toml` file.
-2. Rename it to `config.toml` and fill in the necessary configuration fields specific to the backend.
-3. Run `npm install` to install dependencies.
-4. Run `npm run db:push` to set up the local sqlite.
-5. Use `npm run dev` to start the backend in development mode.
-
-### Frontend
-
-1. Navigate to the `ui` folder and repeat the process of renaming `.env.example` to `.env`, making sure to provide the frontend-specific variables.
-2. Execute `npm install` within the `ui` directory to get the frontend dependencies ready.
-3. Launch the frontend development server with `npm run dev`.
+2. Rename it to `config.toml` and fill in the necessary configuration fields.
+3. Run `npm install` to install all dependencies.
+4. Run `npm run db:push` to set up the local sqlite database.
+5. Use `npm run dev` to start the application in development mode.
 
 **Please note**: Docker configurations are present for setting up production environments, whereas `npm run dev` is used for development purposes.

 ## Installation
 
-Perplexica can be installed using Docker (recommended) or directly on your system.
+There are mainly 2 ways of installing Perplexica - With Docker, Without Docker. Using Docker is highly recommended.

+6. Wait a few minutes for the setup to complete. You can access Perplexica at http://localhost:3000 in your web browser.
 
 **Note**: After the containers are built, you can start Perplexica directly from Docker without having to open a terminal.
 
-The Docker configuration is located in the `docker/` directory, containing:
-- Dockerfile with multi-stage build for efficient images
-- Service configurations for the integrated process manager
-- Nginx reverse proxy configuration
-
 ### Non-Docker Installation
 
 1. Install SearXNG and allow `JSON` format in the SearXNG settings.
 2. Clone the repository and rename the `sample.config.toml` file to `config.toml` in the root directory. Ensure you complete all required fields in this file.
-3. Rename the `.env.example` file to `.env` in the `ui` folder and fill in all necessary fields.
-4. After populating the configuration and environment files, run `npm i` in both the `ui` folder and the root directory.
-5. Install the dependencies and then execute `npm run build` in both the `ui` folder and the root directory.
-6. Finally, start both the frontend and the backend by running `npm run start` in both the `ui` folder and the root directory.
+3. After populating the configuration run `npm i`.
+4. Install the dependencies and then execute `npm run build`.
+5. Finally, start the app by running `npm rum start`
 
 **Note**: Using Docker is recommended as it simplifies the setup process, especially for managing environment variables and dependencies.
 
-See the [installation documentation](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/installation) for more information like exposing it your network, etc.
-
-### Nginx Reverse Proxy
-
-Perplexica includes an Nginx reverse proxy that provides several key benefits:
-
-- **Single Port Access**: Access both frontend and backend through a single port (8080)
-- **Dynamic Configuration**: Works with any domain or IP without rebuilding
-- **WebSocket Support**: Automatic WebSocket URL configuration based on the current domain
-- **Security Headers**: Enhanced security with proper HTTP headers
-
-When using Docker, the reverse proxy is automatically configured. Access Perplexica at `http://localhost:8080` or `http://your-ip:8080` after starting the containers.
+See the [installation documentation](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/installation) for more information like updating, etc.

+1. The message is sent to the `/api/chat` route where it invokes the chain. The chain will depend on your focus mode. For this example, let's assume we use the "webSearch" focus mode.
 2. The chain is now invoked; first, the message is passed to another chain where it first predicts (using the chat history and the question) whether there is a need for sources and searching the web. If there is, it will generate a query (in accordance with the chat history) for searching the web that we'll take up later. If not, the chain will end there, and then the answer generator chain, also known as the response generator, will be started.
 3. The query returned by the first chain is passed to SearXNG to search the web for information.
 4. After the information is retrieved, it is based on keyword-based search. We then convert the information into embeddings and the query as well, then we perform a similarity search to find the most relevant sources to answer the query.

-# Accessing Perplexica over a Network
-
-This guide explains how to access Perplexica over your network using the nginx reverse proxy included in the Docker setup.
-
-## Basic Network Access
-
-Perplexica is automatically accessible from any device on your network:
-
-1. Start Perplexica using Docker Compose:
-   ```bash
-   docker compose up -d
-   ```
-
-2. Find your server's IP address:
-   - **Windows**: `ipconfig` in Command Prompt
-   - **macOS**: `ifconfig | grep "inet "` in Terminal
-   - **Linux**: `ip addr show | grep "inet "` in Terminal
-
-3. Access Perplexica from any device on your network:
-   ```
-   http://YOUR_SERVER_IP:8080
-   ```
-
-## Custom Port Configuration
-
-If you need to use a different port instead of the default 8080:
-
-1. Modify the `docker-compose.yaml` file:
-   ```yaml
-   perplexica:
-     ports:
-       - "YOUR_CUSTOM_PORT:8080"
-   ```
-
-2. Restart the containers:
-   ```bash
-   docker compose down && docker compose up -d
-   ```
-
-## Troubleshooting
-
-If you encounter issues accessing Perplexica over your network:
-
-1. **Firewall Settings**: Ensure port 8080 (or your custom port) is allowed in your firewall
-2. **Docker Logs**: Check for any connection issues with `docker logs perplexica`
-3. **Network Access**: Make sure your devices are on the same network and can reach the server
