+## Helm Chart?
+
+> **The main building block of Helm based deployments are `Helm Charts:` these charts describe a configurable set of dynamically generated Kubernetes resources.** 
+
+> **A Chart is a Helm package. It contains all of the resource definitions necessary to run an application, tool, or service inside a Kubernetes cluster.**
+
+* ***This includes YAML configuration files for***
+    * deployments, 
+    * services, 
+    * secrets, 
+    * config maps etc.. that define the desired state of your application
+
+> **Think of it like the Kubernetes equivalent of a Homebrew formula, an Apt dpkg, or a Yum RPM file.**
+
+> **A Helm chart packages together YAML files and templates that can be used to generate additional configuration files based on parametrized values.**
+
+> **This allows you to customize configuration files to suit different environments and to create reusable configurations for use across multiple deployments.**
+
+> **Additionally, each Helm chart can be versioned and managed independently, making it easy to maintain multiple versions of an application with different configurations.**
+
+> **The charts can either be `stored locally` or `fetched from remote chart repositories`.**
