-A couple of things worth reminding about Slack:
+For any other question you might have about the workshop, feel free to post a message in the `discussions` on GitHub.
 
-1. Do a quick search in the channel before posting. It might be that someone already started a discussion on the same topic.
-2. **Always** reply within [threads](https://slack.com/help/articles/115000769927-Use-threads-to-organize-discussions-) (or open a new one) when you want to join a conversation. The [purpose](https://slack.com/resources/using-slack/tips-on-how-best-to-use-threaded-messages) is to avoid too many unrelated messages that are difficult to navigate in the long run.
+If you come across any bug or have suggestions on how we could improve the content and exercises, feel free to open a new `issue`.
