 When integrating a Simplicité's instance into an existing system with a *distinct identity*, or specific *design guidelines*, you have the possibility to customize and align your instance's UI to those in order to ensure ease of use and familiarity for end-users.

 These customizations can extend to the layout and organization of your Simplicité application.
 
 **Example**: the government's interfaces shall follow the *DSFR design guideline*, so they need to align their Simplicité's interface to match it's rules.

+If your solution is *client-oriented*, you may benefit from creating a *custom front-end* that is tailored to meet the specific needs of your end-users and possible customers. For example you can want your client to be immersed in a specific environment if you wanna apply some specific marketing strategies or user-oriented designs. The idea is that Simplicité will allow you to customize the fronts of your applications, and even take them outside of the solutions if you don't want to mix anything together. 
+
+There are numerous possibilities, but a common example is the one of having products and client ordering them, this is a workflow allowed by Simplicité by default (accessible & illustrated in the *Demo* module). But you could want a specific experience for your customers, for example to preview videos or very specific visualisations of your products. Another possibility is that you want your interfaces to contain widgets or layouts that you've already designed --also maybe implemented-- that you really want to include.
 
 **Example**: in case of a system or application containing orders, possibly emitted by clients, you might benefit from having a minimalist webpage using a more *user-friendly* interface than Simplicité's default one.

 ## Agenda
 
 This part of the documentation follows the following organization and flow:
 
-### Basic customizations
-
-1 - *Theme Editor*; presents the tool and illustrating how to modify the general theme and to adjust specific elements.
-2 - *Addons*; explains how to specificaly customize micro-interactions or overriding foundational styles with *{less}*
-3 - *Widgets Integration*; shows the workflows to integrate existing Simplicité's widget in order to understand the logic behind the integration of external objects.
-
-### Advanced customizations
+0) This introduction document.
+1) Presentation of the [Theme Editor](https://docs.simplicite.io/lesson/docs/front/theme-editor) tool, allowing you to customize the themes and styles of you applications, all within Simplicité's solution.
+2) Overview of the [complementary tool](https://docs.simplicite.io/lesson/docs/front/styles) for theming, allowing you to add even more precise customizations to your applications.
+3) Guide through the [javascript development](https://docs.simplicite.io/lesson/docs/front/javascript-dev) in Simplicité, both outside with the *NPM Library* and inside with the *External Objects*.
+4) Breakdown of the [Ajax Library](https://docs.simplicite.io/lesson/docs/front/lib-ajax) that is useful for javascript development as it presents the core functions and methods to navigate and manipulate Simplicité's concepts and objects.
+5) An understanding of how to create [Custom UI Components](https://docs.simplicite.io/lesson/docs/front/ui-components), breaking down the processes and techniques to do so using Simplicité's  *External Objects* and some *Web Development*.
+6) An extension of *UI Components* to now make those objects outside of Simplicité, creating [external webpages](https://docs.simplicite.io/lesson/docs/front/web-page) that communicates with Simplicité's backend and allow for even more customized fronts.
 
-1 - *Widgets Creation*; understanding how to design and implement custom tools such as widgets or dashboards.
-2 - *Responsive External Objects*; presents how to create and manage responsive, external design elements for seamless integration.  
-3 - *External Webpages (Native)*; shows and illustrates how to develop specific pages fully connected and integrated into your Simplicité's application.  
-4 - *External Webpages (Framework*); explains how to do the same as *3* but using web frameworks instead of native configurations.dsfr.

+Still it is roughly organized in 2 parts, presenting first the basic and very accessible customizations, then delving into more tech aspects of customizations and adressing to web and frontend developpers. All documents are overall independent from each others if your need is only one specific concept, but it is also possible to read them in the right order and get a progressive understanding of how to customize and adapt your Simplicité applications.
