-2. Extract the archive 
+## Extract the archive to `/usr/local`
 
 Unpack the downloaded archive into `/usr/local`, which is the conventional directory for installing system-wide software on Linux. This ensures the Go toolchain is available for all users and integrates cleanly with the system’s environment.
 
 ```console
 sudo tar -C /usr/local -xzf ./go1.25.0.linux-arm64.tar.gz
 ```
 
-3. Add Go to your system PATH
+## Add Go to your shell `PATH`
 
-To make the Go toolchain accessible from any directory, add its binary location to your shell’s PATH environment variable. Updating your `.bashrc` file ensures this change persists across sessions:
