+# Provider Examples
+
+Examples demonstrating how to use different LLM providers with PraisonAI TypeScript.
+
+## Setup
+
+```bash
+# Install dependencies
+cd /path/to/praisonai-ts
+pnpm install
+
+# Set API keys
+export OPENAI_API_KEY=sk-...
+export ANTHROPIC_API_KEY=sk-ant-...
+export GOOGLE_API_KEY=AIza...
+```
+
+## Examples
+
+| File | Description |
+|------|-------------|
+| `multi-provider.ts` | Use multiple providers in one workflow |
+| `openai-compatible.ts` | Use OpenAI-compatible APIs (LM Studio, etc.) |
+| `local-ollama.ts` | Use local Ollama models |
+| `provider-selection.ts` | Dynamic provider selection based on task |
+
+## Running Examples
+
+```bash
+# Run with ts-node or tsx
+npx tsx examples/js/providers/multi-provider.ts
+npx tsx examples/js/providers/openai-compatible.ts
+npx tsx examples/js/providers/local-ollama.ts
