-#Introduction
-If CRAN allows, I really want to call this package `kable%>%`. Well, let's sit down and get back to the reality. Now you have `kableExtra`.
+This package is still in an "as-is" state. You can save a lot of finger-typing time by using it but you still need to understand what is really going on behind the hood, which is still far behind my goal. Also, since the default output format of `kable` is `markdown`, which doesn't support high-level table customization, it may not work well in many cases. I would recommend you to set the `format` option in each `kable` function or to define `options(knitr.table.format = 'html')` or `latex` somewhere in your document.  
 
-Everyone loves `kable`, so do I. It is the most straight forward, convenient table generating function in R (in my opinion). At the same time, it won't through you some useless messages that you need to think of a way to get rid of. Also, if you are planning to "knit" a document, you probably have already have `knitr` loaded. Why would you want to load another "table generator" package if the original one can fulfill your need.  
+#Introduction
+`knitr::kable` wins the favor of a lot of people, including me, by its ultimate simplicity. 
 
 
 Even though there are some other available packages in `R` to build beautiful tables, `kable` is still my go-to function whenever I want to build a table in `rmarkdown` or `Shiny`. After using `kable` for a long time, I can see the only reason that prevents people from using `kable` is its simplicityThis package is designed to enhance `kable`'s functionality without destorying its beauty of simplicity by using our favorite `pipe` syntax.
