 - **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.

-## Installation
+## Overview
 
-1. Install Ollama:
-```bash
-# On macOS
-brew install ollama
-```
+Perplexica is an open-source AI-powered searching tool or an AI-powered search engine that goes deep into the internet to find answers. Inspired by Perplexity AI, it's an open-source option that not just searches the web but understands your questions. It uses advanced machine learning algorithms like similarity searching and embeddings to refine results and provides clear answers with sources cited.
 
-2. Start Ollama:
-```bash
-# Start and enable on login
-brew services start ollama
+Using SearxNG to stay current and fully open source, Perplexica ensures you always get the most up-to-date information without compromising your privacy.
 
-# Or run without auto-start
-/usr/local/opt/ollama/bin/ollama serve
-```
+Want to know more about its architecture and how it works? You can read it [here](https://github.com/ItzCrazyKns/Perplexica/tree/master/docs/architecture/README.md).
 
-3. Pull the required model:
-```bash
-ollama pull mistral
-```

 ## Features
 
-- Business search with location filtering
-- Contact information extraction
-- AI-powered data validation
-- Clean, user-friendly interface
-- Service health monitoring
+- **Local LLMs**: You can make use local LLMs such as Llama3 and Mixtral using Ollama.
+- **Two Main Modes:**
+  - **Copilot Mode:** (In development) Boosts search by generating different queries to find more relevant internet sources. Like normal search instead of just using the context by SearxNG, it visits the top matches and tries to find relevant sources to the user's query directly from the page.
+  - **Normal Mode:** Processes your query and performs a web search.
+- **Focus Modes:** Special modes to better answer specific types of questions. Perplexica currently has 6 focus modes:
+  - **All Mode:** Searches the entire web to find the best results.
+  - **Writing Assistant Mode:** Helpful for writing tasks that does not require searching the web.
+  - **Academic Search Mode:** Finds articles and papers, ideal for academic research.
+  - **YouTube Search Mode:** Finds YouTube videos based on the search query.
+  - **Wolfram Alpha Search Mode:** Answers queries that need calculations or data analysis using Wolfram Alpha.
+  - **Reddit Search Mode:** Searches Reddit for discussions and opinions related to the query.
+- **Current Information:** Some search tools might give you outdated info because they use data from crawling bots and convert them into embeddings and store them in a index. Unlike them, Perplexica uses SearxNG, a metasearch engine to get the results and rerank and get the most relevant source out of it, ensuring you always get the latest information without the overhead of daily data updates.
 
-## Configuration
+It has many more features like image and video search. Some of the planned features are mentioned in [upcoming features](#upcoming-features).
 
-Key environment variables:
-- `SEARXNG_URL`: Your SearxNG instance URL
-- `OLLAMA_URL`: Ollama API endpoint (default: http://localhost:11434)
-- `SUPABASE_URL`: Your Supabase project URL
-- `SUPABASE_ANON_KEY`: Your Supabase anonymous key
-- `CACHE_DURATION_DAYS`: How long to cache results (default: 7)
+## Installation
 
-## Supabase Setup
+There are mainly 2 ways of installing Perplexica - With Docker, Without Docker. Using Docker is highly recommended.
 
-1. Create a new Supabase project
-2. Run the SQL commands in `db/init.sql` to create the cache table
-3. Copy your project URL and anon key to `.env`
+### Getting Started with Docker (Recommended)
 
-## License
+1. Ensure Docker is installed and running on your system.
+2. Clone the Perplexica repository:
 
-MIT
+   ```bash
+   git clone https://github.com/ItzCrazyKns/Perplexica.git
+   ```
 
-## Cache Management
+3. After cloning, navigate to the directory containing the project files.
 
-The application uses Supabase for caching search results. Cache entries expire after 7 days.
+4. Rename the `sample.config.toml` file to `config.toml`. For Docker setups, you need only fill in the following fields:
 
-### Manual Cache Cleanup
+   - `OPENAI`: Your OpenAI API key. **You only need to fill this if you wish to use OpenAI's models**.
+   - `OLLAMA`: Your Ollama API URL. You should enter it as `http://host.docker.internal:PORT_NUMBER`. If you installed Ollama on port 11434, use `http://host.docker.internal:11434`. For other ports, adjust accordingly. **You need to fill this if you wish to use Ollama's models instead of OpenAI's**.
+   - `GROQ`: Your Groq API key. **You only need to fill this if you wish to use Groq's hosted models**
 
-If automatic cleanup is not available, you can manually clean up expired entries:
+     **Note**: You can change these after starting Perplexica from the settings dialog.
 
-1. Using the API:
-```bash
-curl -X POST http://localhost:3000/api/cleanup
-```
+   - `SIMILARITY_MEASURE`: The similarity measure to use (This is filled by default; you can leave it as is if you are unsure about it.)
 
-2. Using SQL:
-```sql
-select manual_cleanup();
-```
+5. Ensure you are in the directory containing the `docker-compose.yaml` file and execute:
 
-### Cache Statistics
+   ```bash
+   docker compose up -d
+   ```
 
-View cache statistics using:
-```sql
-select * from cache_stats;
-```
+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.
+
+### Non-Docker Installation
+
+1. 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.
+2. Rename the `.env.example` file to `.env` in the `ui` folder and fill in all necessary fields.
+3. After populating the configuration and environment files, run `npm i` in both the `ui` folder and the root directory.
+4. Install the dependencies and then execute `npm run build` in both the `ui` folder and the root directory.
+5. Finally, start both the frontend and the backend by running `npm run start` in both the `ui` folder and the root directory.
+
+**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.
+
+### Ollama connection errors
+
+If you're facing an Ollama connection error, it is often related to the backend not being able to connect to Ollama's API. How can you fix it? You can fix it by updating your Ollama API URL in the settings menu to the following:
+
+On Windows: `http://host.docker.internal:11434`<br>
+On Mac: `http://host.docker.internal:11434`<br>
+On Linux: `http://private_ip_of_computer_hosting_ollama:11434`
+
+You need to edit the ports accordingly.
+
+## Using as a Search Engine
+
+If you wish to use Perplexica as an alternative to traditional search engines like Google or Bing, or if you want to add a shortcut for quick access from your browser's search bar, follow these steps:
+
+1. Open your browser's settings.
+2. Navigate to the 'Search Engines' section.
+3. Add a new site search with the following URL: `http://localhost:3000/?q=%s`. Replace `localhost` with your IP address or domain name, and `3000` with the port number if Perplexica is not hosted locally.
+4. Click the add button. Now, you can use Perplexica directly from your browser's search bar.
+
+## One-Click Deployment
+
+[![Deploy to RepoCloud](https://d16t0pc4846x52.cloudfront.net/deploylobe.svg)](https://repocloud.io/details/?app_id=267)
+
+## Deploy Perplexica backend to Google GKE
+
+0: Install `docker` and `terraform` (Process specific to your system)
+1a: Copy the `sample.env` file to `.env`
+1b: Copy the `deploy/gcp/sample.env` file to `deploy/gcp/.env`
+2a: Fillout desired LLM provider access keys etc. in `.env`
+
+- Note: you will have to comeback and edit this file again once you have the address of the K8s backend deploy
+  2b: Fillout the GCP info in `deploy/gcp/.env`
+  3: Edit `GCP_REPO` to the correct docker image repo path if you are using something other than Container registry
+  4: Edit the `PREFIX` if you would like images and GKE entities to be prefixed with something else
+  5: In `deploy/gcp` run `make init` to initialize terraform
+  6: Follow the normal Preplexica configuration steps outlined in the project readme
+  7: Auth docker with the appropriate credential for repo Ex. for `gcr.io` -> `gcloud auth configure-docker`
+  8: In `deploy/gcp` run `make build-deplpy` to build and push the project images to the repo, create a GKE cluster and deploy the app
+  9: Once deployed successfully edit the `.env` file in the root project folder and update the `REMOTE_BACKEND_ADDRESS` with the remote k8s deployment address and port
+  10: In root project folder run `make rebuild-run-app-only`
+
+If you configured everything correctly frontend app will run locally and provide you with a local url to open it.
+Now you can run queries against the remotely deployed backend from your local machine. :celebrate:

-# Perplexica Search API Documentation
-
-## Overview
-
-Perplexica’s Search API makes it easy to use our AI-powered search engine. You can run different types of searches, pick the models you want to use, and get the most recent info. Follow the following headings to learn more about Perplexica's search API.
-
-## Endpoint
-
-### **POST** `http://localhost:3001/api/search`
-
-**Note**: Replace `3001` with any other port if you've changed the default PORT
-
-### Request
-
-The API accepts a JSON object in the request body, where you define the focus mode, chat models, embedding models, and your query.
-
-#### Request Body Structure
-
-```json
-{
-  "chatModel": {
-    "provider": "openai",
-    "model": "gpt-4o-mini"
-  },
-  "embeddingModel": {
-    "provider": "openai",
-    "model": "text-embedding-3-large"
-  },
-  "optimizationMode": "speed",
-  "focusMode": "webSearch",
-  "query": "What is Perplexica",
-  "history": [
-    ["human", "Hi, how are you?"],

-  ]
-}
-```
-
-### Request Parameters
-
-- **`chatModel`** (object, optional): Defines the chat model to be used for the query. For model details you can send a GET request at `http://localhost:3001/api/models`. Make sure to use the key value (For example "gpt-4o-mini" instead of the display name "GPT 4 omni mini").
-
-  - `provider`: Specifies the provider for the chat model (e.g., `openai`, `ollama`).
-  - `model`: The specific model from the chosen provider (e.g., `gpt-4o-mini`).
-  - Optional fields for custom OpenAI configuration:
-    - `customOpenAIBaseURL`: If you’re using a custom OpenAI instance, provide the base URL.
-    - `customOpenAIKey`: The API key for a custom OpenAI instance.
-
-- **`embeddingModel`** (object, optional): Defines the embedding model for similarity-based searching. For model details you can send a GET request at `http://localhost:3001/api/models`. Make sure to use the key value (For example "text-embedding-3-large" instead of the display name "Text Embedding 3 Large").
-
-  - `provider`: The provider for the embedding model (e.g., `openai`).
-  - `model`: The specific embedding model (e.g., `text-embedding-3-large`).
-
-- **`focusMode`** (string, required): Specifies which focus mode to use. Available modes:
-
-  - `webSearch`, `academicSearch`, `writingAssistant`, `wolframAlphaSearch`, `youtubeSearch`, `redditSearch`.
-
-- **`optimizationMode`** (string, optional): Specifies the optimization mode to control the balance between performance and quality. Available modes:
-
-  - `speed`: Prioritize speed and return the fastest answer.
-  - `balanced`: Provide a balanced answer with good speed and reasonable quality.
-
-- **`query`** (string, required): The search query or question.
-
-- **`history`** (array, optional): An array of message pairs representing the conversation history. Each pair consists of a role (either 'human' or 'assistant') and the message content. This allows the system to use the context of the conversation to refine results. Example:
-
-  ```json
-  [
-    ["human", "What is Perplexica?"],
-    ["assistant", "Perplexica is an AI-powered search engine..."]
-  ]

-# Ethical Web Scraping Guidelines
-
-## Core Principles
-
-1. **Respect Robots.txt**
-   - Always check and honor robots.txt directives
-   - Cache robots.txt to reduce server load
-   - Default to conservative behavior when uncertain
-
-2. **Proper Identification**
-   - Use clear, identifiable User-Agent strings
-   - Provide contact information
-   - Be transparent about your purpose
-
-3. **Rate Limiting**
-   - Implement conservative rate limits
-   - Use exponential backoff for errors
-   - Distribute requests over time
-
-4. **Data Usage**
-   - Only collect publicly available business information
-   - Respect privacy and data protection laws
-   - Provide clear opt-out mechanisms
-   - Keep data accurate and up-to-date
-
-5. **Technical Considerations**
-   - Cache results to minimize requests
-   - Handle errors gracefully
-   - Monitor and log access patterns
-   - Use structured data when available
-
-## Implementation
-
-1. **Request Headers**
-```typescript
-const headers = {
-  'User-Agent': 'BizSearch/1.0 (+https://bizsearch.com/about)',
-  'Accept': 'text/html,application/xhtml+xml',
-  'From': 'contact@bizsearch.com'
-};
-```
-
-2. **Rate Limiting**
-```typescript
-const rateLimits = {
-  requestsPerMinute: 10,
-  requestsPerHour: 100,
-  requestsPerDomain: 20
-};
-```
-
-3. **Caching**
-```typescript
-const cacheSettings = {
-  ttl: 24 * 60 * 60, // 24 hours
-  maxSize: 1000 // entries
-};
-```
-
-## Opt-Out Process
-
-1. Business owners can opt-out by:
-   - Submitting a form on our website
-   - Emailing opt-out@bizsearch.com
-   - Adding a meta tag: `<meta name="bizsearch" content="noindex">`
-
-2. We honor opt-outs within:
-   - 24 hours for direct requests
-   - 72 hours for cached data
-
-## Legal Compliance
-
-1. **Data Protection**
-   - GDPR compliance for EU businesses
-   - CCPA compliance for California businesses
-   - Regular data audits and cleanup
-
-2. **Attribution**
-   - Clear source attribution
-   - Last-updated timestamps
-   - Data accuracy disclaimers
-
-## Best Practices
-
-1. **Before Scraping**
-   - Check robots.txt
-   - Verify site status
-   - Review terms of service
-   - Look for API alternatives
-
-2. **During Scraping**
-   - Monitor response codes
-   - Respect server hints
-   - Implement backoff strategies
-   - Log access patterns
-
-3. **After Scraping**
-   - Verify data accuracy
-   - Update cache entries
-   - Clean up old data
-   - Monitor opt-out requests
