Usually I explain one of my CICD pipeline to others with words such like github action + argo-cd. I am not sure if they understand it. A picture is worth a thousand words. Here is my CICD pipeline picture. I used excalidraw to draw the diagram. Excalidraw link is https://excalidraw.com/#json=D7EzmscoRDH8LYLZmtr2l,FVEHlWoxFXtoqqHpReMaEw. Feel free to use it.
