-# Learning gem5 Tutorial and gem5 Users' Workshop
+## COVID-19 Update April 8th
+
+ISCA is going to be taking place virtually due to the COVID-19 pandemic. See <https://iscaconf.org/isca2020/> for more information.
+On the plus side, we believe this will make the gem5 workshop more inclusive! Rather than limiting attendees to those that can travel to Valencia, anyone will be able to participate!
+We are making the following changes to the original call for participation:
+
+1. The deadline for submitting an abstract is now May 1st. You can still use the following link to submit an abstract: <https://forms.gle/UnpFXRvpLEFKJBb46>
+2. For accepted abstracts, you will be able to produce a short video and a blog post for the gem5 blog. In the week leading up to the workshop, we will advertise all of the accepted works.
+3. We will hold a synchronous virtual Q&A session (or sessions) during the week of June 1st (the original time when ISCA was scheduled). During these session(s), we will ask the authors of the accepted works to attend to encourage discussion with the broader gem5 community. Specific times for these will be announced soon. We will work with the community to choose a time that is inclusive to those in different time zones.
+
+**Update on the gem5 Tutorial:** Similarly for the gem5 tutorial, we will post videos before the week of June 1st and hold session(s) for Q&A the week of June 1st.

+## gem5 Workshop and Tutorial with ISCA 2020
 
 In conjunction with [ISCA 2020](https://www.iscaconf.org/isca2020/), we will be holding a [gem5 Tutorial](#learning-gem5-tutorial) and [Workshop](#3rd-gem5-users-workshop-afternoon) on May 30th in Valencia, Spain.
 In the morning, we will be running a Learning gem5 Tutorial, and in the afternoon we will have a gem5 users' workshop.
