  -### Install for RHEL based distro (Amazon Linux 2017.03)
  -Now we haven't prebuild library in some shared place. You can build
  -library yourself. Please refer to How-to-build section.
  +### RHEL-based distributions (Amazon Linux 2017.03)
  +Pre-built libraries are not provided for RHEL-based distributions. Please look [here](doc/rhel-build.md)
  +for details on building from source for RHEL-based distributions.
  -After build add to LD_LIBRARY_PATH environment variable path to builded library.
  -It's necessary for dynamic linkage your application with libindy.
  +After successfully compiling `libindy`, you will need to add the path containing `libindy.so` to the
  +`LD_LIBRARY_PATH` environment variable. This is required for your application to link to
  +`libindy`.
