_The easy way to keep diagrams up-to-date with the code_

What ?
------

Diagrams are :

* **100%** text described
* built with _gitlab-ci_
* deployed on _gitlab-pages_

So easy to maintain that your diagrams could be **still up-to-date** even **10 months later**!!!

How ?
-----

Just push [diagram sources][src] and [.gitlab-ci.yml][yml] will build & deploy it on _pages_ :

![Physical data model with shared files][pdm-shared].

[D.R.Y.][dry] !
---------------

Using _!include_ or _!includeurl_ PlantUML's [preprocessor][preprocessor] directives allows you to share common sources between diagrams.

In this repo, _shared files_ diagrams [share same data][part] :

- associations
- attributes
- classes
- keys
- legend
- relations

Hence, if you add something in your shared sources, all diagrams will get it !
