-## 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`.

-# JSON Formatting

-The ability to add new radio band allocation identifiers and color maps relies on JSON files. Proper formatting of these JSON files is important for reference and readability. The following guides will show you how to properly format the JSON files for their respective uses.
