How do I import a script?
If you have a script that you would like to import, go to My scripts and click on Import Code. A dialogue box will appear asking you to choose a file to import. Select Browse/Choose (depending on your browser) and select the file from the folder where you saved it. Click on Import and the file will be uploaded to My scripts on www.microbit.co.uk where you can select edit to work on it again. You can also drag and drop a .jsz file or .hex file onto the My scripts area and it will be available for editing in the My scripts area.
