 ### Dynamic libraries
 
-If Rakudo is installed into $HOME directory (this is also the case when
-rakubrew <https://rakubrew.org/> is used) then some modules may fail to
-install due to missing dynamic libraries. This could be caused by a
-situation when the library is not provided by macOS system itself but
-installed using Homebrew or MacPorts package managers. In this case the
-library cannot be loaded by rakudo binary. This is a security precaution
-taken by modern versions of macOS. The precaution works by restricting the
-directories available for loading dynamic libraries from only to the
-system-predefined set and those where the application binary is actually
-located. For example, if "rakudo" binary is installed under "$HOME/raku/bin"
-then aside of the system-wide locations it can access libraries in
-"$HOME/raku/lib" only.

 For the above stated reason, if a problem with availability of a dynamic
 library occurs then creating a symlink to the library in one of the
 following locations could help:
 
 - <rakudo binary location path>/../lib
-- $HOME/lib (should be created if doesn't exists yet)
+- $HOME/lib (should be created if doesn't exist yet)
 
 The latter is one of the allowed system locations.
