+This is an example how to create an R Markdown document in RKWard.
+
+The structure of such documents is always the same.
+1. The YAML header between the  ---
+2. An optional Global Settings chunck
+3. The main text containing markdown, LaTeX, R (even other languages like python), HTML and other elements
+
+In this template we show main concept of markdown like
+- heading
+- footnotes
+- links
+- equations
+- lists (ordered, unordered, nested)
+- plots and
+- tables
+Please feel free to adjust it to your needs.
+-->
+
+```{r, echo=TRUE}
+# Defaults to suppress warnings and messages
+# Figure height and width are set to 7 inches
+# See more options by running str(knitr::opts_chunk$get())
+
+knitr::opts_chunk$set(
+  echo = FALSE, error = FALSE, warnings = FALSE, message = FALSE,
+  collapse = FALSE, fig.width = 4, fig.height = 4
+)
+```
+
+# The RKWard IDE and GUI
+
+RKWard is an *easy to use* and **easily extensible** IDE/GUI^[IDE: Integrated Development Environment. GUI: Graphical User Interface] for [R](https://www.r-project.org/). It aims to combine the power of the R-language with the ease of use of commercial statistics tools.
+
+## Features of RKWard
+
+RKWard’s features include:
+
+- Spreadsheet-like data editor
+- Syntax highlighting, code folding and code completion
+- Data import (e.g. SPSS, Stata and CSV)
+- Plot preview and browsable history
+- R package management
+- Workspace browser
+- GUI dialogs for all kinds of statistics and plots
+- Developer tools integration via kateparts
+  - git
+  - terminal tool view (Linux only)
+  - Text filter
+
+and many more features.
+
+## Data handling
+
+RKWard can handle all kinds of data from simple to complex. Here is an example where a part of the iris data is shown as table.
+
+```{r}
+data <- iris[1:4, ]
+knitr::kable(data, caption = "Table caption text.")
+```
+
+It is also possible to make tables by hand as shown next.
+
+
+| Right  | Left  | Default   | Center    |
+|-------:|:------|-----------|:---------:|
+| 12     | 12    | 12        | 12        |
+| 123    | 123   | 123       | 123       |
+| 1      | 1     | 1         | 1         |
+:Example for a handmade table (pure `markdown`)
+
+
+### Plotting in RKWard
+
+There many ways to to plots in RKWard. These are for example:
+
+1. via the GUI menus (e.g., barplot, boxplot, ...)
+2. via the R script and the preview or
+3. in a R Markdown document as shown next.
+
+Let us take a simple code to make four plots of random data in a single row, for example:
+
+
+```
+par(mfrow = c(2,2))
+
+for (i in 1:4) {
+ plot(rnorm(10))
+}
+```
+
+If we put the code in the following R Markdown chunk (note the 'r' in the curly braces) the plot looks as follows:
+
+```{r}
+par(mfrow = c(1,2))
+
+for (i in 1:4) {
+ plot(rnorm(10))
+}
+```
+
+# Conclusion
+
+RKWard is a useful tool. This RKWard version is used with the R version `r  getRversion()`.
+
+If you like RKWard consider to donate. Some small amount for a cup of coffee or a cup of H~2~O is totally fine.
