 # Frequently Asked Questions
 
+### @description Frequently asked questions and answers from our users.
+
 ### Where can I get a BBC micro:bit?
 
 More information at [http://uk.farnell.com/bbc-microbit](http://uk.farnell.com/bbc-microbit).
 
+### How do I send feedback?
+
+Find the small bubble icon on the bottom of the editor and
+post your feedback from there!
+
+### How do I save my code?
+
+The web editor automatically saves your code in the browser cache. Simply reopen the browser and navigate to the web editor 
+to reopen your latest project. You can also open previous project stored locally through **More -> Open Project**.
+
+The project source is also stored in each compiled ``.hex`` file. Drag and drop the ``.hex`` file into the web editor to load the project.
+
+To share your project with others, you can use the **Embed** feature. It stores your project in the cloud and creates a URL that you can share with others.
+
+If you are using [Visual Studio Code](/code), all your programs are stored as files on your computer and you can use your favorite source control system as needed.
