 ## Introduction
 
-Beamer has a lot of themes which are build-in([Beamer Matrix](https://hartwork.org/beamer-theme-matrix/)) or developed by others([overleaf](https://www.overleaf.com/gallery/tagged/presentation), [github](https://github.com/martinbjeldbak/ultimate-beamer-theme-list)). But there is almost no satisfaction for me. What I mainly focus on is just **simple colors** and **clear navigation**. So I made a simple theme for myself by modifying the defaut theme. I will be encouraged if you like it too.
-
 The value of this project is as follows
 
-- a template easy to be applied, easy to change the color, easy to change the way of navigation
-- a content tex file to test the beauty of other themes
+- A beamer theme focusing on simple color and clear navigation. 
+- The color and navigation can be changed easily. And I will talk about the tricks to set them up.

 The code has passed with pdflatex and Xelatex.

 ## Navigation
 
-For a long-time presentation, a suitable navigation is necessary. I selected four ways of navigation with different advantages.(**focus on the top of each slide**)
