CommonApp Activity Detail Character Limit

I am trying to add the details of my activities and because of the character limit, I am having hard time explaining them. What is expected to be written there? I can't even fit my project's name and explaination there.</p>

<p>What I would do is fit what I can, and attach a separate resume that has the full activity name and detail necessary.</p>

<p>It seems I will do so.</p>
