simply add the following to your `init.el`/`.emacs`[^1] file:

```lisp

# Usage
|
||||
|
||||
There are several ways to make `irony-mode` aware of what it should look for in
|
||||
it's completion. My preferred method, though not the only one, is to simply add
|
||||
my compile flags in the special `.clang_complete` file as part of the working
|
||||
directory of the project.
|
||||
|
||||
For an STM32F0 project, the context of the `.clang_complete` file would be:
|
||||
```
|
||||
|
||||
```text
|
||||
-I./libopencm3/include
|
||||
-DSTM32F0

directory</sub>
