+## Why does Homebrew on Linux recommend that I install to `/home/linuxbrew/.linuxbrew`?
+
+The precompiled binary bottles of non-relocatable bottles can only be used if you install in `/home/linuxbrew/.linuxbrew`, otherwise they have to be built from source. Install Homebrew on Linux in `/home/linuxbrew/.linuxbrew/` if possible so that you can use precompiled binary packages (known as bottles) for non-relocatable formula. If you do not yourself have admin privileges, consider asking your admin staff to create a `linuxbrew` role account for you with home directory `/home/linuxbrew`.
