 # Homework rules
 
+## Solutions
+
+Homeworks plays significant role in your final grade so you have to solve them.
+
+But we **kindly ask you** not to publish solutions (e.g. public repo on your GitHub account).
+Because we aren't able to provide unique tasks for every run (although we update some every time).
+Also it's no good in spoilering solutions to your fellows - they lose an occasion to practice ML.
+
+It's good to have a repo with the task solved, so you could have a *private* repo either on GitHub with student account or on [GitLab](https://gitlab.com/) or anywhere else.
