+## Code
+
+bug fixes, improvements and several other things accepted.
+
+the coding style is described here:
+
+- indentation: two spaces
+- modified 1TBS style:
+  - no spaces in function calls
+  - spaces between arguments in function declarations
+  - no spaces in operations except for `||` and `&&`
+  - no space between variable name and assignment
+  - space between macro in string literals
+  - C++ pointer style: `void* variable` rather than `void *variable`
+  - indent switch cases
+  - preprocessor directives not intended
+  - if macro comprises more than one line, indent
+
+some files (particularly the ones in `src/engine/platform/sound` and `extern/`) don't follow this style.
+
+you don't have to follow this style. I will fix it after I accept your contribution.
