 Install the most recent available version under `/usr/local`:
 
+```bash
     $ git clone git://github.com/rtomayko/git-sh.git
     $ cd git-sh
     $ make
     $ sudo make install
+```
 
 Start a shell with `git-sh`:
 
+```bash
     $ git-sh
     master!git-sh> help
+```
 
 Use the `PREFIX` environment variable to specify a different install location.
 For example, under `~/bin`:
 
+```bash
     $ make install PREFIX=~
+```
 
 Basic Usage
 -----------
 
 Typical usage is to change into a git working copy and then start the shell:
 
+```bash
     $ cd mygreatrepo
     $ git sh
     master!mygreatrepo> help
+```
 
 Core git commands and git command aliases defined in `~/.gitconfig` can be
 used as top-level commands:
 
+```bash
     master!mygreatrepo> checkout -b new
     new!mygreatrepo> log -p
     new!mygreatrepo> rebase -i HEAD~10
+```
 
 It's really just a normal bash shell, though, so all commands on `PATH` and any
 aliases defined in `~/.bashrc` are also available:
 
+```bash
     new!mygreatrepo> ls -l
     new!mygreatrepo> vim somefile
+```
 
-*IMPORTANT: `rm`, `mv`, and `diff` are aliased to their git counterparts.  Use
-`command(1)` (e.g., `command rm`) or qualify the command (e.g. `/bin/rm`)
-to use system versions.*

 value to `auto`:
