# project-commands
> **Warning**

This example shows how to create scripts for your project, by leveraging [mission-control](https://github.com/Platonic-Systems/mission-control)
This is a **potential** alternative to:
- Using a `Makefile` to manage your project's scripts
- Using the popular [Scripts To Rule Them All](https://github.com/github/scripts-to-rule-them-all) approach (having a `scripts/` folder)
- Using a `bin/` folder
## Explanation
In this example we use the [avro-tools](https://avro.apache.org/) to convert our scripts from `.avdl` to `.avsc`.
You don't need to know anything about avro to understand mission-control and use this example (that's nix baby 🚀).
When setting up [mission-control](https://github.com/Platonic-Systems/mission-control), we add
one script called `build`. Because of `wrapperName = "run";`, once we open the shell created by nix,
the commands will be listed as `run build`.
mission-control depends on flake-root, which also exposes the helpful `$FLAKE_ROOT` variable.
After creating the scripts, we need to pass the newly created scripts to the desired shell, in this example we use the default shell.
## Usage
Run:
```sh
nix develop
```
And mission-control will print in the new shell the available commands (you should see only one).
Try running
```sh
run build
```
