+# 2 Livox SDK API
+
+Livox SDK API provides a set of C style functions which can be conveniently integrated in C/C++ programs. Please refer to the [Livox SDK API Reference](https://livox-sdk.github.io/Livox-SDK/) for further information.
+
+## 2.1 Installation
+The installation procedures in Ubuntu 16.04/14.04 32-bit LTS are shown here as examples.
+### 2.1.1 Ubuntu 16.04/14.04 32-bit LTS
+#### Dependencies
+Livox SDK requires [CMake 3.0.0+](https://cmake.org/), [Apache Portable Runtime (APR) 1.61+](http://apr.apache.org/) and [Boost 1.54+](https://www.boost.org/) as dependencies. You need to install boost, cmake using apt:
+```
+sudo apt install cmake libboost-atomic-dev libboost-system-dev
+```
+And download the newest apr linux source file in [Apache Portable Runtime (APR) 1.61+](http://apr.apache.org/):
+```
+tar -zxvf apr-1.X.X.tar.gz
+cd apr-1.X.X
+./configure --prefix=/usr/local/apr --disable-lfs
+make && sudo make install
+```
+#### Compile Livox SDK
+In the Livox SDK directory, run the following commands to compile the project:
+```
+git clone https://github.com/Livox-SDK/Livox-SDK.git
+cd Livox-SDK/build
+PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/apr/lib/pkgconfig/ && export PKG_CONFIG_PATH
+cmake ..
+make
+sudo make install
+```
+As the PKG_CONFIG_PATH will only take effect on the current terminal, next time please re-add it when you build project in another terminal.
