A project like this is only possible with the effort of many people.
If you want to contribute to make SimulIDE a better application there are several ways to do it:
Perhaps the most important is reporting any problem or bug you find while using the simulator.
You can report bugs or other problems in SimulIDE Forum.
The translation system is starting to get shape.
If you want to translate to your language have a look at Forum/General_Discussion/Translations.
There are many tasks that don’t require coding or special skills.
For example creating subcircuits like the 74 series ICs, writing help files, etc
If you are a developer, you are very welcome to contribute to the project.
Another way to support the project and watch some videos is subscribing to SimulIDE youtube Channel.
And of course sharing this pages, videos, etc in social media.
Thanks for your interest!!
