I use Bonobo Git Server 4.0.0.0 for Windows. It work fine. I use readme.md as information notice. I can mark a block of code using 4 spaces before every line (in this case syntax formating don't work). Unfortunately,
(empty line)
```java
(some program code...)
```
(or other program language) construction don't work for this markdown file. However, separate repository java files is parsed and displayed correctly in a Web browser. Maybe there's another way to mark code ?
