# 3 KEIL
## 3.1 Modify the Configuration File
The scons --target=mdk5 command generates the current project based on the project under sdk\tools\build\template\template.uvprojx.
For the uvprojx project, after opening template.uvprojx in keil, modifying it, saving it, and exiting, the default result of the next scons --target=mdk5 command will follow the modifications made to the template.uvprojx project.
