+# ccc Settings
+
+Configuration lives in two YAML files, both created automatically by `ccc init`.
+
+## User-Level Settings (`~/.cocoindex_code/global_settings.yml`)
+
+Shared across all projects. Controls the embedding model and extra environment variables for the daemon.
+
+```yaml
+embedding:
+  provider: sentence-transformers   # or "litellm" (default when provider is omitted)
+  model: sentence-transformers/all-MiniLM-L6-v2
+  device: mps                       # optional: cpu, cuda, mps (auto-detected if omitted)
+  min_interval_ms: 300              # optional: pace LiteLLM embedding requests to reduce 429s; defaults to 5 for LiteLLM
+
+envs:                               # extra environment variables for the daemon
+  OPENAI_API_KEY: your-key          # only needed if not already in the shell environment
+```
+
+### Fields
+
+| Field | Description |
+|-------|-------------|
+| `embedding.provider` | `sentence-transformers` for local models, `litellm` (or omit) for cloud/remote models |
+| `embedding.model` | Model identifier — format depends on provider (see examples below) |
+| `embedding.device` | Optional. `cpu`, `cuda`, or `mps`. Auto-detected if omitted. Only relevant for `sentence-transformers`. |
+| `embedding.min_interval_ms` | Optional. Minimum delay between LiteLLM embedding requests in milliseconds. Defaults to `5` for LiteLLM and is ignored by `sentence-transformers`. Set explicitly to override the default. |
+| `envs` | Key-value map of environment variables injected into the daemon. Use for API keys not already in the shell environment. |
+
+### Embedding Model Examples
+
+**Local (sentence-transformers, no API key needed):**
+
+```yaml
+embedding:
+  provider: sentence-transformers
+  model: sentence-transformers/all-MiniLM-L6-v2    # default, lightweight
+```
+
+```yaml
+embedding:
+  provider: sentence-transformers
+  model: nomic-ai/CodeRankEmbed                     # better code retrieval, needs GPU (~1 GB VRAM)
+```
+
+**Ollama (local):**
+
+```yaml
+embedding:
+  model: ollama/nomic-embed-text
+```
+
+**OpenAI:**
+
+```yaml
+embedding:
+  model: text-embedding-3-small
+  min_interval_ms: 300
+envs:
+  OPENAI_API_KEY: your-api-key
+```
+
+**Gemini:**
+
+```yaml
+embedding:
+  model: gemini/gemini-embedding-001
+envs:
+  GEMINI_API_KEY: your-api-key
+```
+
+**Voyage (code-optimized):**
+
+```yaml
+embedding:
+  model: voyage/voyage-code-3
+envs:
+  VOYAGE_API_KEY: your-api-key
+```
+
+For the full list of supported cloud providers and model identifiers, see [LiteLLM Embedding Models](https://docs.litellm.ai/docs/embedding/supported_embedding).
+
+### Important
+
+Switching embedding models changes vector dimensions — you must re-index after changing the model:
+
+```bash
+ccc reset && ccc index
+```
+
+## Project-Level Settings (`<project>/.cocoindex_code/settings.yml`)
+
+Per-project. Controls which files to index. Created by `ccc init` and automatically added to `.gitignore`.
+
+```yaml
+include_patterns:
+  - "**/*.py"
+  - "**/*.js"
+  - "**/*.ts"
+  # ... (sensible defaults for 28+ file types)
+
+exclude_patterns:
+  - "**/.*"              # hidden directories
+  - "**/__pycache__"
+  - "**/node_modules"
+  - "**/dist"
+  # ...
+
+language_overrides:
+  - ext: inc             # treat .inc files as PHP
+    lang: php
+```
+
+### Fields
+
+| Field | Description |
+|-------|-------------|
+| `include_patterns` | Glob patterns for files to index. Defaults cover common languages (Python, JS/TS, Rust, Go, Java, C/C++, C#, SQL, Shell, Markdown, PHP, Lua, etc.). |
+| `exclude_patterns` | Glob patterns for files/directories to skip. Defaults exclude hidden dirs, `node_modules`, `dist`, `__pycache__`, `vendor`, etc. |
+| `language_overrides` | List of `{ext, lang}` pairs to override language detection for specific file extensions. |
+
+### Editing Tips
+
+- To index additional file types, append glob patterns to `include_patterns` (e.g. `"**/*.proto"`).
+- To exclude a directory, append to `exclude_patterns` (e.g. `"**/generated"`).
+- After editing, run `ccc index` to re-index with the new settings.
