+Cpsrc is a tool to automate and enhance competitive programmer's experience. It works well with neovim and C++. You can also modify it to use the editor and programming language of your choice.
+
+Cpsrc offers several features:
+- Automatic template 
+- Fast and easy compilation (using Makefile and precompiled headers)
+- Colored input/output
+
 # Installation
 
 Clone the repository and make setup.sh executable and run it:
