 ### Permisson issues
 
-By default npm uses `/usr/local/lib/node_modules` as the install location for globally installed packages. This causes problems since users typically lack write permissions there. It is therefore recommended to either use a version manager, or change npm's default install location manually (which is what we did above). For more details on how to do this, see [this article](https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally).
