-- **[Ollama](docs/ollama-configuration.md)** - Local LLM provider
+1. **Open QodeAssist Settings**
-- **[llama.cpp](docs/llamacpp-configuration.md)** - Local LLM server
+2. **Select a Preset** - Choose from the Quick Setup dropdown:
-- **[Anthropic Claude](docs/claude-configuration.md)** - Сloud provider
+   - **Anthropic Claude** (Sonnet 4.5, Haiku 4.5, Opus 4.5)
-- **[OpenAI](docs/openai-configuration.md)** - Сloud provider
+   - **OpenAI** (gpt-5.2-codex)
-- **[Mistral AI](docs/mistral-configuration.md)** - Сloud provider
+   - **Mistral AI** (Codestral 2501)
-- **[Google AI](docs/google-ai-configuration.md)** - Сloud provider

-- **LM Studio** - Local LLM provider
+3. **Configure API Key** - Click "Configure API Key" button and enter your API key in Provider Settings
-- **OpenAI-compatible** - Custom providers (OpenRouter, etc.)
+
+All settings (provider, model, template, URL) are configured automatically. Just add your API key and you're ready to go!
+
+### Manual Provider Configuration
+
+For advanced users or local models, choose your preferred provider and follow the detailed configuration guide:
+
+**Local providers:**
+- **[Ollama](docs/ollama-configuration.md)** — native Ollama API
+- **Ollama (OpenAI-compatible)** — Ollama's `/v1` endpoint for tool-calling models
+- **[llama.cpp](docs/llamacpp-configuration.md)** — local `llama-server`
+- **LM Studio** — OpenAI-compatible Chat API
+- **LM Studio (Responses API)** — newer models that require the Responses endpoint
+
+**Cloud providers:**
+- **[Anthropic Claude](docs/claude-configuration.md)** — manual setup guide
+- **[OpenAI](docs/openai-configuration.md)** — Chat Completions and Responses API
+- **[Mistral AI](docs/mistral-configuration.md)** / **Codestral**
+- **[Google AI](docs/google-ai-configuration.md)** — Gemini
+- **OpenAI-compatible** — OpenRouter and any custom endpoint
+
+### Recommended Models for Best Experience
+
+For optimal coding assistance, we recommend using these top-tier models:
+
+**Best for Code Completion & Refactoring:**
+- **Claude 4.5 Haiku or Sonnet** (Anthropic)
+- **GPT-5.1-codex or codex-mini** (OpenAI Responses API)
+- **Codestral** (Mistral)
+
+**Best for Chat Assistant:**
+- **Claude 4.5 Sonnet** (Anthropic) - Outstanding reasoning and natural conversation flow
+- **GPT-5.1-codex** (OpenAI Responses API) - Latest model with advanced capabilities
+- **Gemini 2.5 or 3.0** (Google AI) - Latest models from Google
+- **Mistral large** (Mistral) - Fast and capable
+
+**Local models:**
+- **Qwen3-coder** (Qwen) - Best local models
 
 ### Additional Configuration
 
+- **[Agent Roles](docs/agent-roles.md)** - Create AI personas with specialized system prompts
+- **[Chat Summarization](docs/chat-summarization.md)** - Compress conversations to save context tokens
 - **[Project Rules](docs/project-rules.md)** - Customize AI behavior for your project

 - **[File Context](docs/file-context.md)** - Attach or link files for better context
 - Automatic syncing with open editor files (optional)
 - Extended thinking mode (Claude, other providers in plan) - Enable deeper reasoning for complex tasks
 
 ### Quick Refactoring
 - Inline code refactoring directly in the editor with AI assistance
-- Selection-based improvements with instant code replacement
-- Built-in quick actions (repeat, improve, alternative)
 - **Custom instructions library** with search and autocomplete
 - Create, edit, and manage reusable refactoring templates
 - Combine base instructions with specific details
 - **[Learn more](docs/quick-refactoring.md)**
 
 ### Tools & Function Calling
-- Read project files
+
-- List and search in project
+Chat and Quick Refactor can call tools to inspect and modify your project. Each tool can be individually enabled/disabled in settings.
-- Access linter/compiler issues
+
-- Enabled by default (can be disabled)
+| Tool | What it does |
+|------|--------------|
+| `list_project_files` | List files in the active project(s) |
+| `find_file` | Find a file by name or partial path |
+| `read_file` | Read file contents (project or absolute path) |
+| `search_project` | Grep / symbol search across project sources |
+| `create_new_file` | Create a new empty file on disk |
+| `edit_file` | Replace content in a file (old → new) |
+| `build_project` | Build the active project and return compiler output |
+| `get_issues_list` | Read current linter / compiler diagnostics |
+| `execute_terminal_command` | Run a shell command (with confirmation) |
+| `todo_tool` | Track multi-step task progress during a conversation |
+
+### MCP Server
+
+QodeAssist can run an **MCP (Model Context Protocol) server** on `localhost`, exposing the tools above to external clients — so you can use QodeAssist's project awareness from Claude Code CLI, VS Code, Cursor, Claude Desktop, or any other MCP-capable client.
+
+- **Enable** in `Tools → Options → QodeAssist → MCP Server`
+- **Transport**: HTTP + SSE by default; a stdio bridge is provided for clients that only speak stdio (e.g. Claude Desktop)
+- **Ready-to-copy snippets** for Claude Code, VS Code, and the bridge are available via the "Show connection instructions" button in settings
+
+### MCP Client Hub
+
+QodeAssist can also act as an **MCP client**, connecting to external MCP servers and making their tools available to Chat and Quick Refactor alongside the built-in ones.
+
+- **Configure** servers in `Tools → Options → QodeAssist → MCP Client`
+- **Transports**: stdio and HTTP/SSE
+- **Limitation**: authenticated MCP servers (OAuth / token-protected) are **not supported yet** — only servers that accept unauthenticated local connections work for now
