+
+Manual removal:
+- Linux/macOS: delete `~/.local/bin/tricode` (or wherever you put it) and remove any custom PATH entry you added.
+- Windows: delete `%LOCALAPPDATA%\Tricode\tricode.exe` and remove `%LOCALAPPDATA%\Tricode` from your User PATH via Environment Variables if still present.

 ### Configuration Options
 
-- `openai_api_key`: Your OpenAI API key (required)
-- `openai_base_url`: Custom API endpoint (optional, defaults to OpenAI's official API)
-- `openai_model`: Model to use (optional, defaults to gpt-4o-mini)
+- `default_provider`: Which provider to use by default (e.g., `openai`, `anthropic`)
+- `providers.openai.api_key`: Your OpenAI API key (required for OpenAI)
+- `providers.openai.base_url`: API base URL (optional)
+- `providers.openai.model`: Model name (defaults to `gpt-4o-mini`)
+- `providers.anthropic.api_key`: Your Anthropic API key (required for Anthropic)
+- `providers.anthropic.base_url`: API base URL (optional)
+- `providers.anthropic.model`: Model name (e.g., `claude-3-5-sonnet-20241022`)
 
 ### Environment Variable Override
 
-All configuration options can be overridden via environment variables, which take precedence over `settings.json`.
+Environment variables take precedence over `settings.json`.
+
+Two levels are supported:
 
-Environment variable naming: `TRICODE_` + UPPERCASE config key
+1) Global keys (rarely needed): `TRICODE_` + UPPERCASE of top-level key
 
+2) Provider-specific keys (recommended): `TRICODE_{PROVIDER}_{KEY}`
+
+Examples:
 ```bash
+# OpenAI
 export TRICODE_OPENAI_API_KEY="sk-your-api-key"
 export TRICODE_OPENAI_BASE_URL="https://api.openai.com/v1"
-export TRICODE_OPENAI_MODEL="gpt-4o"
