As an optional feature, you can include a custom logo at the beginning of your form once it has been deployed as a new survey project.
For this you first need a file called `form_logo.png` which contains your logo. Make sure the file size is no more than a few kilobytes since it will load faster and won't be very big in any case.
In your survey project, open the Project settings box. Under 'Existing form files' click Add document to select the file on your computer and upload it.
When you get the form (whether on KoBoCollect or in Enketo Web forms) the logo will be downloaded along with the rest of the form and displayed at the very beginning.
