+#### How provider-budget-routing works
+
+1. **Budget Tracking**: 
+   - Uses Redis to track spend for each provider
+   - Tracks spend over specified time periods (e.g., "1d", "30d")
+   - Automatically resets spend after time period expires
+
+2. **Routing Logic**:
+   - Routes requests to providers under their budget limits
+   - Skips providers that have exceeded their budget
+   - If all providers exceed budget, raises an error
+
+3. **Supported Time Periods**:
+   - Format: "Xd" where X is number of days
+   - Examples: "1d" (1 day), "30d" (30 days)
+
+4. **Requirements**:
+   - Redis required for tracking spend across instances
+   - Provider names must be litellm provider names. See [Supported Providers](https://docs.litellm.ai/docs/providers)
