+With Envoy installed successfully on your GCP C4A Arm virtual machine, you will proceed to validate that the Envoy is running as expected.
 
 ## Validate Envoy installation with a baseline test
 
-In this section, we covered how to create a minimal Envoy config, start Envoy with it, and verify functionality using `curl`. 
-The test confirmed that Envoy listens on port **10000**, forwards requests to `httpbin.org`, and returns a successful **200 OK** response.

 ### Create a Minimal Configuration File
 
-Using a file editor of your choice, create a file named `envoy_config.yaml`, and add the below content to it. This file configures Envoy to listen on port **10000** and forward all traffic to `http://httpbin.org`. The host_rewrite_literal is essential to prevent 404 Not Found errors from the upstream server.

 #### Summary of the curl Output
 
-- **Successful Connection:** The **curl** command successfully connected to the Envoy proxy on **localhost:10000**.
-- **Correct Status Code:** Envoy successfully forwarded the request and received a healthy **200 OK** response from the upstream server.
-- **Host Header Rewrite:** The **Host** header was correctly rewritten from **localhost:10000** to **httpbin.org** as defined in the configuration.

+- **Correct Status Code:** Envoy successfully forwarded the request and received a successful `200 OK` response from the upstream server.
+- **Host Header Rewrite:** The Host header was correctly modified from `localhost:10000` to `httpbin.org` as defined in the configuration.
 - **End-to-End Success:** The proxy is fully operational, proving that requests are correctly received, processed, and forwarded to the intended backend.
