-Usage
-=====
-Installation
-------------
+# Coding rules
+- use `boxtee` to execute each original `git` command 
+
+# Usage
+## Installation
 Use `./install.bash dev` to get an installation from the current sources.
 
-Debug mode
-----------
+## Debug mode
 Use `export GED=1` to switch on the debug of `git elegant` or `unset GED` to switch off. 
 
-Unit tests
-==========
+# Unit tests
 [bats](https://github.com/sstephenson/bats) is used for unit testing. 
 
-Addons
-------
+## Addons
 Add the following line to the test file if the extension is required:
 - `load addons-common` to have the working test (**mandatory**)
 - `load addons-git` to interact with real git repository (**optional**)
@@ -21,24 +19,20 @@ Add the following line to the test file if the extension is required:
 - `load addons-cd` to fake `cd` command (**optional**)
 - `load addons-read` to fake `read` command (**optional**)
 
-Writing tests
--------------
+## Writing tests
 1. **Use `setup()` or `teardown()`** bats methods only in the tests.
 2. Use **`check` instead of bats `run`** to execute a command to be tested.
 3. If `addons-fake` or `addons-git` is used, call `clean-fake` or `clean-git` within a `teardown()` method.
 
-Assertions
-----------
+## Assertions
 - `[ "${lines[0]}" = "+ the space " ]` for a output line (index starts from 0)
 - `[ "$status" -eq 2 ]` for a command status
 - `[ "${#lines[@]}" -eq 0 ]` for an empty command output
 
-Test name template
-------------------
+## Test name template
 Use the following test name template - `'<command args>': <describe what will be tested>` like `'check -s': trailing spaces in the staged changes`.
 
-Run
----
+## Run
 Use one of the following commands to run the unit tests:
 - `bats src/test`
 - `./run-tests`

 Elegant git
 ===========
-Your `git` experience will be changed forever.
+`git elegant` is a `git` extension which allows simplifying of `git` interaction.
+
+`git elegant` always says which original git command will be executed.
