diff: -# Setup Indy SDK build environment for Ubuntu based distro (Ubuntu 16.04)
  +etup Indy SDK build environment for Ubuntu based distro (Ubuntu 16.04)
  1. Install Rust and rustup (https://www.rust-lang.org/install.html).
  1. Install required native libraries and utilities:
  libssl-dev \
  libsqlite3-dev \
  libsodium-dev \
  - libzmq3-dev
  + libzmq3-dev \
  + libncursesw5-dev
  ```
  -1. Checkout and build the library:
  +
  +1. Build `libindy`
  ```
  git clone https://github.com/hyperledger/indy-sdk.git
  cargo build
  cd ..
  ```
  +
  1. Run integration tests:
  * Start local nodes pool on `127.0.0.1:9701-9708` with Docker:
  RUST_TEST_THREADS=1 TEST_POOL_IP=10.0.0.2 cargo test
  ```
  +1. Build `indy-cli` (Optional)
  +
  + `indy-cli` is dependent on `libindy` and should be built after it.
  +
  + ```
  + cd cli/
  + RUSTFLAGS=" -L ../libindy/target/debug" cargo build
  + ```
  + If you have followed the instructions to build libindy above, the default build type will be `debug`
  +
  + Make sure to add the libindy to the path. Using bash:
  + ```
  + echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/libindy/target/{BUILD TYPE}" >> ~/.bashrc
  + sudo ldconfig
  + source ~/.bashrc
  + ```
  + To run indy-cli, navigate to `cli/target/debug` and run `./indy-cli`
  +
  See [libindy/ci/ubuntu.dockerfile](https://github.com/hyperledger/indy-sdk/tree/master/libindy/ci/ubuntu.dockerfile) for example of Ubuntu based environment creation in Docker.
