 ===========
 
 ColdDB is a minetest mod that implements a serverless, asynchronous, NoSQL database engine.<br>
-It provides a key or key-value storage system using plain Lua tables. It also can iterate through the keys.<br>
-It is not required to add this mod to secure.trusted_mods this mod will still work.

 Usage
 ===========
 
-Copy *colddb.lua* file to your minetest mod or game. Copy the code from colddb's init file to your mods init file<br>
-Then create a lua file for handling database's or any file you like.<br>
