-> *This package allow you to install Webmin quickly and simply on a YunoHost server.  
-If you don't have YunoHost, please see [here](https://yunohost.org/#/install) to know how to install and enjoy it.*
 
 **Note:** This app has **root** access which can change core things in the system, thus **breaking the YunoHost**. Use it carefully and read the [documents](https://doxfer.webmin.com/Webmin/Main_Page) two times before changing values.
 
-## Webmin
+## Overview
 [Webmin](http://www.webmin.com/index.html) is a **web-based** interface for system **administration** for Unix. Using any modern web browser, you can setup user **accounts**, **DNS**, **file sharing** and much more. Webmin removes the need to manually **edit Unix configuration** files like **/etc/passwd**, and lets you manage a system from the **console or remotely**.

-- [Webmin](http://www.webmin.com/)
-- [Webmin source code at Github](https://github.com/webmin/webmin)
-
 ## Important points
+
 - Only **root** (system user) can connect 
 - Webmin will **update itself** when system updates are run. So no need to **run upgrade script** once installed.
 - Only **user** given permission at time of the installation can **access** the Webmin 
 - Installation can only be done on **root path**. Eg. webmin.domain.tld 
 - No **multi-instance** for webmin as it is a system integrated app

-### About --weight and --time
-### ynh_script_progression will show to your final users the progression of each scripts.
-### In order to do that, --weight will represent the relative time of execution compared to the other steps in the script.
-### --time is a packager option, it will show you the execution time since the previous call.
-### This option should be removed before releasing your app.
-### Use the execution time, given by --time, to estimate the weight of a step.
-### A common way to do it is to set a weight equal to the execution time in second +1.
-### The execution time is given for the duration since the previous call. So the weight should be applied to this previous call.
