Hello,
I want to fix a typo in this 
The problem is I don't know what tools you are using to draw schematics nor I'm having access to an easily editable file to edit them.
Suggestions
We could create schematics by using something like:
If it's not an option we can use digrams.net wich:
- Is not platform specific
- It can export diagrams in PNG, SVG and others formats.
- the .drawio format used to edit the diagrams is just an XML file
We have some advantage by doing that:
- Tracking the modifications of schemas is facilitated since diagrams will become simple text.
- Tools that create and edit schema will become the same for every contributors.
What do you thin about it ? :)
