  ## Building `indy-cli`

  In the above command, substitute `{BUILD_TYPE}` with `release` or `debug` as appropriate.
  -In some instances, when `cargo` calls `rustc`, the linker can have difficult finding `libindy.so`
  -even after specifying the directory containing it in `LD_LIBRARY_PATH`. Specifying `RUSTFLAGS` in
  -the command above will tell `rustc` to also check `../libindy/target/{BUILD_TYPE}` for libraries.
  +If you have installed `libindy.so` to a system-wide location and subsequently run `ldconfig`, you do not need
  +to specify the `RUSTFLAGS` environment variable as `rustc` should be able to find `libindy.so` without additional
  +help.

  +If not, however, `indy-cli` needs help to be able to find `libindy.so` while being built. Setting `LD_LIBRARY_PATH`

  +command above will tell `rustc` to also check `../libindy/target/{BUILD_TYPE}` for libraries.
