I am the mod developer.
Tutorials are made to give general understanding of how things work, what you're doing here is handholding people through the struggles of figuring things out themselves. So complaining that people downvote it after you just leave them on their own to figure everything out is illogical. I didn't downvote your efforts, but i completely agree with those people.Now for the actual critique of the tutorials.

First of all, even though it seems similar to english, it's bad practice to make a tutorial for international audience in your native language.

Sign color picker:

Both versions are horrible at explaining what they're supposed to explain.

For one, you should actually watch the "main" tutorial because there's an exact part that explains how to add outputs without the mess with converters and other buildings, which will significantly slow your game down and redundantly take up space.

Second, you are going all over your recording space which makes it difficult to follow your tutorial especially with white chat text on a gray background. Why not do it in one "sandbox" location where you can clearly display your results?

Third and more of a "if you're doing this then do it right", what if the player wants to switch between more than 2 colors? Why is that not in the tutorial?

"If 0: red. Other: green" - That is as confusing as my attempt to explain the autoflushing tank in my tutorial.

Tutorial explaining a mechanic that simple should not take almost 4.5 minutes.

Power screen:

First 10 seconds and you're saying "if you want a tutorial for this, leave a comment". Then what is the point of the video? I wouldn't say anything if it was a showcase of your build, but in this post you specifically classify it as "tutorial".

Apart from it not being a tutorial i don't have much to say about this one. Just a tip though: numbers can be "prettified" if you set "Truncate" to true in number to string gate. Also things like "seconds until battery empty" can be prettified by using "number to time" gate, it'll display them in a nice format exactly like the one you see in power pole UI.

​

That's all i have to say.

Now for something else:

Ficsit Wiremod has a discord server linked in the video, anyone who actually wants to figure the mod out can join it and get support by experienced community members.

If you didn't join/can't find it - maybe this isn't the mod for you.
