+## Setup
+
+Check include file in `py_wrapper.hpp` & `solver.hpp` (python version)
+
+```
+#include "/usr/include/python3.6m/Python.h"
+#include "/usr/include/python3.6m/numpy/arrayobject.h"
+#include "/usr/include/python3.6m/numpy/arrayscalars.h"
 ```
 
+If there exist no files in `/usr/include/python3.6m`, type commands as follows:
+
+```
+sudo apt-get install python3-dev
+sudo apt-get install python3-numpy
 ```
-(sudo) rm -rf build
-(sudo) pip3 uninstall mySolverModule
+
+Type command as follows:
+
+```
+sudo python3 setup.py install
+```
+
+To confirm, type `pip3 freeze`. `mySolverModule==1.0.0` will be listed.
+
+[Uninstall]
+```
+sudo rm -rf build
+sudo pip3 uninstall mySolverModule
+```
