-
-## 🚀 Using the OpenAPI Spec
-
-### Viewing the Documentation
-
-#### Option 1: Swagger UI (Local)
-```bash
-# Using npx (no installation needed)
-npx swagger-ui-watcher openapi.yaml
-```
-
-Then open: http://localhost:8080
-
-#### Option 2: Swagger Editor Online
-1. Go to https://editor.swagger.io/
-2. File → Import File
-3. Select `openapi.yaml`
-
-#### Option 3: VS Code Extension
-Install "OpenAPI (Swagger) Editor" extension and open `openapi.yaml`
-
-### Generating Client SDKs
-
-Use the OpenAPI Generator to create client libraries:
-
-```bash
-# Install OpenAPI Generator
-npm install -g @openapitools/openapi-generator-cli
-
-# Generate JavaScript client
-openapi-generator-cli generate \
-  -i openapi.yaml \
-  -g javascript \
-  -o ./client-sdk/javascript
-
-# Generate Python client
-openapi-generator-cli generate \
-  -i openapi.yaml \
-  -g python \
-  -o ./client-sdk/python
-
-# Generate TypeScript client
-openapi-generator-cli generate \
-  -i openapi.yaml \
-  -g typescript-axios \
-  -o ./client-sdk/typescript
-```
-
-### Generating Server Stubs
-
-Generate server boilerplate in various languages:
-
-```bash
-# Generate Node.js Express server
-openapi-generator-cli generate \
-  -i openapi.yaml \
-  -g nodejs-express-server \
-  -o ./generated-server
-
-# Generate Python Flask server
-openapi-generator-cli generate \
-  -i openapi.yaml \
-  -g python-flask \
-  -o ./generated-server-python
-```
-
-### API Testing with OpenAPI
-
-#### Using Postman
-1. Import `openapi.yaml` into Postman
-2. Postman will automatically create a collection
-3. Configure authentication and environment variables
-4. Run requests directly
-
-#### Using Insomnia
-1. Create → Import from → File
-2. Select `openapi.yaml`
-3. All endpoints will be imported
-
-#### Using curl with examples
-The spec includes examples that can be used with curl:
-
-```bash
-# Generate API key
-curl http://localhost:3000/api/v1/auth
-
-# List accounts
-curl -H "x-api-key: 1234" \
-  http://localhost:3000/api/v1/accounts
-
-# Create account
-curl -X POST http://localhost:3000/api/v1/accounts \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: 1234" \
-  -d '{
-    "owner": "John Doe",
-    "balance": 1000,
-    "currency": "COSMIC_COINS"
-  }'
-```
-
-### Contract Testing
-
-Use the OpenAPI spec for contract testing:
-
-```bash
-# Install Dredd
-npm install -g dredd
-
-# Run contract tests
-dredd openapi.yaml http://localhost:3000
-```
-
-### Mock Server
-
-Create a mock server from the OpenAPI spec:
-
-```bash
-# Using Prism
-npm install -g @stoplight/prism-cli
-
-# Start mock server
-prism mock openapi.yaml
-
-# Mock server will run on http://127.0.0.1:4010
-```
