+## Prerequisite Notes
+
+The `prerequisites-cmds.sh` can be used either like a true Shell script, or the commands which are part of it can be executed one by one. It depends on your preference.
+
+`prerequisites-cmds.sh` downloads and installs the following software:
+
+1. Linux Docker container runtime (`docker.io` or `docker-ce` pkg depending on your OS).
+2. `kubectl` binary.
+3. `helm` binary.
+4. Helm plugins: `helm-diff`.
+5. `helmfile` binary.
+6. `kind` binary.
+
 > **NOTE**: Those of you who would like to use the automation with Helm v2 - please switch to branch `helm-v2`.
