The website contains downloadable files categorized into sections: Modding Tools, Game Modifications, Language Packs, Custom Maps and New Characters, etc. Mods can also be downloaded as files from Klei's official website, or from Don't Starve mods website ,which must be manually placed into the appropriate '/mods/' directory of the game. The player can then enable/disable the installed mods by going into the 'Mods' menu from the main menu, and ticking the mods' respective checkboxes. This will automatically download the mods into the game. The simplest way to download and install mods is to subscribe to them in the Steam Community Workshop.
