Hi Ricardo

GPS for new comer's can/may be a struggle depending on what other IDE you are
familiar with, as they all tend to be different to a lesser or larger degree 
depending on their pedigree, be it Emacs, Eclipse, Visual Code, JetBrains IDE's
or Visual Studio.

Their are a few add-in's to the above IDE's that may suit you better, depending
on your IDE of choice, these being

1) Emacs - https://groups.google.com/forum/#!topic/comp.lang.ada/FaYk4LzQG7E
2) Eclipse - I believe Adacore had/have a plugin ?
3) Visual Code - Their are few plugins for Ada available, which includes a LSP
(ie intellisense capabilities)
3) JetBrains - ?
4) Visual Studio 2017/2019 - Their is a plugin called "VisualAda" available at 
https://marketplace.visualstudio.com/items?itemName=AlexGamper.VisualAda

If you advise us on what your preference is (WRT IDE of choice) then we can
better advise you, as their are a few choices available to you, be it GPS or
any of the above.
