🛠️ Refactor suggestion
Avoid double-installing kubectl & add checksum verification
The manual install block downloads a second copy of kubectl right after the one that apt-get install kubectl pulled in (line 26). Keeping both copies introduces version drift and can break future apt upgrade operations. Pick one installation path (apt or manual), or clearly mark the second as an alternative.
If you keep the manual route, follow the upstream docs and verify the SHA-256 (or GPG) signature before moving the binary into a privileged directory:
-# 1. Download the latest version of kubectl
-curl -LO "https://dl.k8s.io/release/$(curl -Ls https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
-# 2. Make it executable
-chmod +x kubectl
-# 3. Move it to a directory in your PATH
-sudo mv kubectl /usr/local/bin/
-# 4. Verify installation
-kubectl version --client
+# Alternative: manual install of the latest binary
+# Comment out the `apt-get install kubectl` line above if you use this path.
+RELEASE=$(curl -Ls https://dl.k8s.io/release/stable.txt)
+curl -LO "https://dl.k8s.io/$RELEASE/bin/$(uname -s | tr '[:upper:]' '[:lower:]')/$(uname -m)/kubectl"
+curl -LO "https://dl.k8s.io/$RELEASE/bin/$(uname -s | tr '[:upper:]' '[:lower:]')/$(uname -m)/kubectl.sha256"
+echo "$(cat kubectl.sha256) kubectl" | sha256sum --check
+chmod +x kubectl
+sudo mv kubectl /usr/local/bin/
+kubectl version --clientThis removes the duplicate install and ensures integrity of the downloaded binary.

In README.md lines 28 to 38, the current instructions manually download kubectl
even if it was installed via apt-get, causing duplicate installations and
potential version conflicts. To fix this, either remove the manual download
steps if apt-get is used or clearly label the manual installation as an
alternative method. If keeping the manual method, add a step to verify the
SHA-256 checksum or GPG signature of the downloaded kubectl binary before moving
it to /usr/local/bin to ensure its integrity.
