-<note important>The location of all files and directories in Hyperbola comply with the Filesystem Hierarchy Standard (FHS), version 3.0, with the exception of **/usr/** that was removed. Therefore directories such as **/include/**, **/libexec/**, **/share/**, **/src/** and **/local/** were moved from **/usr/** to **/**.</note>+<note> 
 +The term "essential" refers from all binaries, command binaries and libraries installed in folders located directly in the root directory, not inside /usr.
