 # Terminal Instance
 
+Terminal instance is the main API that allow you to interact with the jQuery Terminal library. To
+access the terminal instance you can use return value from terminal call. Or access it with `this`
+keyword inside methods.
+
+```javascript
+const term = $('body').terminal({
+    echo(...args) {
+        this.echo(args.join(' '));
+    }
+}, {
+    checkArity: false,
+    greetings: false
+});
+
+term.echo('Welcome to my terminal');
+```
+
+In above code you code we disabled the terminal and call echo on terminal instance in `term`
+constant.  We also use `this.echo(...)` to implement `echo` command.
