 ## Installation
 
-1. Install VoiceText SDK
-2. Put license file
-3. Build this package
+### 1. Install VoiceText SDK
+#### If you have voicetext sdk install binary, please follow the official guide and install both engine and SDK
+#### If you don't have the sdk install binary but have ReadSpeaker API binary, please follow the guide below.
+1. Install VoiceText Engine by official guide
+2. Copy VoiceText API binaries to VoiceText binary directory
+  VoiceText API package includes binary libraries and header file. You have to copy those of them to specific directory by executing following commands.
+  ```bash
+  cd /path_to_api_package_directory # e.g. cd ~/Downloads/RS_VTAPI_SDK_Linux_4.3.0.2/20201113_VTAPI4.3.0.2_LINUX
+  cd bin/x64 # You have to cd x86 if your system is x86 architecture
+  # Assuming VoiceText engine's talker is hikari, type is D16. If it is different, please set appropriate directory.
+  sudo cp -a * /usr/vt/hikari/D16/bin # Don't forget to add -a not to break symbolic link. 
+  ```
+### 2. Put license file
+### 3. Build this package
 
 ```bash
 cd /path/to/catkin_workspace
