+## Code Style
+
+Each mod must provide `mod.conf`.
+Each mod which add API functions should store functions inside a global table named like the mod.
+Public functions should not use self references but rather just access the table directly.
+Functions should be defined in this way:
+```
+function mcl_xyz.stuff(param) end
+```
+Insteed of this way:
+```
+mcl_xyz.stuff = function(param) end
+```
+Indentation must be unified, more likely with tabs.
+
+Time sensitive mods should make a local copy of most used API functions to improve performances.
+```

 ## Features > 1.12
 
 If you want to make a feature that was added in a Minecraft version later than 1.12, you should fork MineClone5 (mineclone5 branch in the repository) and add your changes to this.
