 If there are additional providers you want to use you can submit a PR to the [Models.dev repo](https://github.com/sst/models.dev). If configuring just for yourself check out the Config section below.
 
+### Global Config
+
+Some basic configuration is available in the global config file.
+
+```toml title="~/.config/opencode/config.toml"
+theme = "opencode"
+provider = "anthropic"
+model = "claude-sonnet-4-20250514"
+autoupdate = true
+```
+
+You can also extend the models.dev database with your own providers and models by placing a `provider.toml` file in `~/.config/opencode/providers`.
+
+```toml title="~/.config/opencode/providers/openrouter/provider.toml"
+[provider]
+name = "OpenRouter"
+env = ["OPENROUTER_API_KEY"]
+id = "openrouter"
+npm = "@openrouter/ai-sdk-provider"
+```
+
+And models in `~/.config/opencode/providers/openrouter/models/[model-id]`.
+
+```toml title="~/.config/opencode/providers/openrouter/models/anthropic/claude-3.5-sonnet.toml"
+name = "Claude 4 Sonnet"
+attachment = true
+reasoning = false
+temperature = true
