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

-
-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`.
