 ## Files
 
+- `httpbin.yaml` - Go implementation of httpbin.org for testing HTTP requests and responses
+  - Based on the [go-httpbin](https://github.com/mccutchen/go-httpbin) project
+  - Includes readiness and liveness probes to ensure the application is healthy
+  - Provides various endpoints for testing different HTTP features (/get, /post, /status, etc.)
+  - Runs on port 8080
+
 - `k6.yaml` - k6 load testing tool configuration for performance testing
   - References the external script file `test-script.js`
   - When applying this manifest, use: `kubectl create configmap k6-test-script --from-file=test-script.js=./k8s/apps/test-script.js -n tools`
