Minecraft 1.14.4 .

1. creating World .
2. copying the "data\oreveins" folder from "oreVeins" .. ".jar" to "saves\<<World>>\data" .
3. changing the "data\oreveins\oreveins" folder and content 's names .
4. setting ``"conditions": null`` in the files, setting ``enableDefaultVeins = false`` in "config\oreveins-comon.toml" .
5. loading the World and using "/reload" .

(this is all the info contained in the Readme)

6. no vein options shown at "/findveins " .

please help

There's a number of things here

• You need to make a Data Pack (link contains help on how exactly to do that, if not there's plenty of other resources on the format)
• You need to have a separate namespace for your data pack, otherwise you'll end up overriding the existing veins instead of adding new ones.
• The data/oreveins/oreveins is the path within your datapack (i.e. similar to data/[namespace]/advancements from vanilla). So yours would be data/[your namespace]/oreveins
• Don't use null as a entry for conditions, just omit the conditions.
