I have heard that devs are planning to take part in a big conference or something like this. I think that it is really important and can influence on project popularity
participation of project representatives in conferences and presentations has a very positive impact on the popularity of the project, such participation should be much more
Of course, participation in exhibitions and conferences is a very important marketing for the successful promotion of the project.
You just need to start with real communication with your client, then there will be a good result.
