Perhaps that's the right solution. I'm not sure what the advantages of umpirsky's command over the simple `chmod -R 777`. But we should also consider the fact someone could want to simply download a .zip of the project, and upload that to their web host over FTP. Maybe they don't have access to any command line, therefore they can't use composer, or chmod. Some of the FTP clients have a GUI for setting file permissions. Perhaps this discussion is ancillary to adding the `chmod` lines to the CLI installation instructions though.
