# MOD Development Tutorial MOD Introduction: MOD is divided into "configuration file" and "modification file" directories. The configuration file mainly displays information such as the MOD name and author and the MOD modification file directory. **MOD placement directory:** ``` PC: {GameDir}\Mesozoic Dawn_Data\StreamingAssets\Mods\ Android: {SdcardDir}\Android\data\com.nextindie.mesozoicdawn\files\Mods\ ``` **MOD file path directory description: Please place the file strictly according to the following directory, otherwise a read error will occur.** {% code title="MOD Directory Structure" lineNumbers="true" %} ```lua /Mods/ -- MOD root directory /Mods/DemoMod/ -- MOD directory /Mods/DemoMod/CharacterAsset/ -- Character data configuration file directory /Mods/DemoMod/SkinsAsset/ -- Character skin graphic texture directory ``` {% endcode %} **MOD configuration file: The configuration file suffix is ​​".mod", and the configuration parameters are as follows** {% code title="MOD Configuration File Information" %} ```lua ModConfig = { Name = "Demo", --MOD name, used for system representation and display to players (*Note: Please keep this name consistent with the file name) Author = "Gamer", --MOD author, used to show to players Path = "DemoMod/", --MOD file path Version = "0.0.1", --MOD version, used to distinguish MOD versions SupportedVersion = "0.6.*" --Game versions supported by MOD (* means no restrictions) } ``` {% endcode %}
