+- Namespaces: `CamelCase`
+- Classes: `CamelCase`
+- Structs: `CamelCase_t`
+- Members: `camelCase`
+- Enum: `SNAKE_CASE`

+        otherStuff();
+        myLongFunction();
+    }
+}
+```
+
+Note: If it makes the code cleaner, remember to use the `?` keyword instead of a `if else` statement.
+
+## Pointers
+
+Please use `type* name` for pointers.
+
+## Structure
+
+Headers and their associated C++ files shall be in the same directory. All headers must use `#pragma once` instead of other include guards. Only include files in a header that are being used in that header. Include the rest in the associated C++ file.
+
+# Modules
+
+## Module Naming Convention
+
+All modules names must be `snake_case`. If the module is a source, it must end with `_source`. If it is a sink, it must end with `_sink`.
+
+For example, lets take the module named `cool_source`:
+
+- Directory: `cool_source`
+- Class: `CoolSourceModule`
+- Binary: `cool_source.<os dynlib extension>`
+
+## Integration into main repository
+
+If the module meets the code quality requirements, it may be added to the official repository. A module that doesn't require any external dependencies that the core doesn't already use may be enabled for build by default. Otherwise, they must be disabled for build by default with a `OPT_BUILD_MODULE_NAME` variable set to `OFF`.
