+### Typescript React Component
+
+To get started with React and Typescript you need to import the React Module.
+Next you define your Interface for the Props. Typescript requires that you define the types as well.
+After you defined your interfaces you pass them as Type Arguments into the React.Component function call. The first Parameter is for the Props and the second for the State.
+As soon as you passed in the Props you are able to display them.
+
+```tsx
+import * as React from "react";
+
+interface IProps {
+    greeting: string;
+}
+
+class TypescriptComponent extends React.Component<IProps, {}> {
+  public render(): JSX.Element {
+    return <div>{this.props.greeting}</div>;
+  }
+}
+
+```
+
+```tsx
+const htmlNode: HtmlElement = document.getElementById("demoTypescript");
+if (htmlNode) {
+    ReactDOM.render(<TypescriptComponent greeting="Hello 30 Seconds of Code" />, htmlNode);
+}
+```
