Problem with custom technologies .lang file

[Demonmiker]

My .lang files don't work.
Where should I put them?
(Sorry for my bad English)

If you're making technologies from the config, then you can't use .lang files, you just write the name of the technology in the .json file like so:

{
    "display": {
        "title": "insert name here"
        // ...
    }
    // ...
}
