 ### When to Use Each Oracle
 
 **Use Pyth Network when:**
+
 - You need institutional-grade data quality
 - High-frequency updates are required
 - Confidence intervals are important
 - Trading major crypto assets
 - Maximum precision is needed
 
 **Use Reflector Oracle when:**
+
 - Cost efficiency is priority
 - Stellar ecosystem assets
 - Proven track record on Stellar

 ## Deployment Steps
 
 1. **Build the contract**:
+
 ```bash
 cargo build --target wasm32-unknown-unknown --release
 ```
 
 2. **Deploy to Stellar**:
+
 ```bash
 soroban contract deploy --wasm target/wasm32-unknown-unknown/release/predictify_hybrid.wasm
 ```
 
 3. **Initialize with admin**:
+
 ```bash
 soroban contract invoke --id <contract_id> -- initialize --admin <admin_address>
 ```
 
 4. **Set token contract**:
+
 ```bash
 soroban contract invoke --id <contract_id> -- set_token_contract --token_contract <token_address>
