You need to log-in to your ARMS portal, click CPD Diary on the left-hand side of the screen, and then click the Add CPD Diary Entry button at the top of the page. You should record your CPD Activity Name, Hours, Accreditation type, a brief Description of the activity (this will be used to evaluate your claim) and the Activity Completion Date.
You must also upload Supporting Documentation as evidence of your claim (if not an ARMS Module or ARMS event). Evidence may be email confirmation of your attendance from your line supervisor, a pdf certificate of attendance, formal confirmation of results, etc.
