# Configuration
## File Resolution
By default, mmtc looks for configuration file at `<your config directory>/mmtc/mmtc.ron`.
Your config directory may differ depending on the operating system, so mmtc tries to find your config directory with [dirs crate](https://docs.rs/dirs-next/*/dirs_next/fn.config_dir.html).
This setting can be overwritten by the command line argument `-c` or `--config`.
If no config file was given from the command line and mmtc failed to find your config directory, the [default configuration](mmtc.ron) would be used.
## File Structure
The configuration file is written in [ron](https://github.com/ron-rs/ron), an expressive object notation.
Check out its [specification wiki](https://github.com/ron-rs/ron/wiki/Specification) if you are having trouble figuring out its syntax.
The whole file should be a [`Config` struct](#Config).
### Config

`Fixed(n, item)` | tuple | non-negative integer, \<type> | `item` with a fixed length of `n`
