Two things:
1) Any plugin from TV Addons is not going to get discussed on this site. Check out the piracy policy and list of banned addons.
2) I think you misunderstand what I'm suggesting you do. I'm suggesting that you read the tutorials and then have a go yourself at creating your plugin. I'm not volunteering to do it myself.

#1 is a minor point here because you're not looking for support with that plugin itself, but you do need to be aware of the rules of what you can and can't discuss on this site.

I want to build a plug-in that is legal .. .. The site I'm talking about is legal .. license.
Please do not worry about it.
For the construction of the plugin .. I have no idea where to start ..
At least tell me about what to do ...

ok, one more time in case you didn't pay attention.

you can find all the info, including tutorials, in our wiki:
Add-on_development (wiki)

step one: read the documentation
step two: learn some python
step three: look at other plugins/add-ons
step four: just start trying

READ .......... COPY ............ PASTE ......... SAVE......... RUN.........ERROR ............... REPEAT if this has not happend 50 to 100 times you ent trying hard enough

The way I develop my addons is to start by creating a folder (as per pipcan's post) and then creating the addon.xml file (as this is what Kodi needs to make your addon/plugin accessible to users). Once that's set up I write the first version of the script. I try running the script at which point (at least 99 times out of 100) I'll get a "script failed" message. I take a look at the kodi.log file and realise I've made some stupid typo etc, fix it, and then try running the addon again.

So, to answer your questions:
"How can I check if it works?": Basically, it works if it does what you want it to do! If it doesn't then it's not working but you can check for errors in the log file.

"I need to install the add[on] every time?": No. Assuming the addon.xml file is correct then there's no need to reload (slightly different for services I think but I don't think you're writing one of those yet).

"You can plugin that working?": Sorry, not sure what you mean? If you just want to look at the code of existing plugins then you can have a look at the code in your "addons" folder.

"How much time its take? to do it?": There's no answer to this question as it depends on lots of factors: How much time do you have? Are you trying to do something very difficult? How much experience do you have at writing addons?

I'd really recommend that you go over the Hello World example and read the other posts to as there are some helpful tips in there.

If you've never done it before then, yes, it will be hard. But that's not a reason for you not to try!

I would suggest taking an existing plugin, taking a look at the code and seeing how it handles logging in, extracting video links and providing them to Kodi.

I've not written video plugins before but if I did want to do so, I'd start by looking at this page.

you've been given all the advise you can possibly expect of us.
now it's up to you to get your hands dirty.
or if you're not up for the task, just forget about the idea.
