description.txt - tModLoader/tModLoader GitHub Wiki

You can create a description.txt file in the top level of your mod's source directory.

This file is a plain text file that contains a short description of your mod. In game, it will appear in the Mods menu when the More Info button is selected. The description file is handled as plain-text and thus any formatting (such as markdown) will not be handled.

Including a description.txt is very important and helps players find mods they are interested in.

description_workshop.txt

An additional file, decription_workshop.txt, can optionally be included. If present, the content of this text file will automatically be placed on the mod's Workshop page when uploading or updating the mod instead of the description.txt. The regular description.txt will still be displayed in game. BB Code markup tags can be included in the decription_workshop.txt which Steam will parse.
