+# Creating C++ programs in Codio
+
+### Make a new file
+Use **File > New File...** or right-click in the file tree to create a new file. You can right-click in the file tree to rename or delete files.
+
+As Codio detects which file is in focus, simply put your cursor into whichever code editor you want to compile and run.
+
+### Compile, Run or Both
+Use the Run button (that looks like a Rocketship) to Compile and Run the file your cursor is in.
+
+![](https://global.codio.com/platform/readme.resources/RunMenuJava.png)
+
+Use the drop-down arrow to the right of the "Compile & Run" option to change the button to just Compile or just Run.
+
+### Debug your Code
+Use the "Debug Current File" on the far right of the top menu bar to launch the debugger targeting the file your cursor is in.
+
+### Reconfigure your Panels for easier development
+Use the **View > Panels** menu on the top tool bar to segment your screen.
+
+Simply drag the tab of the file or terminal (the part with the name) you want to move into the new panel.
