# First Steps
## Create a project
```bash
dcr new my-app
cd my-app
```
Structure:
```
my-app/
├── dcr.toml
└── src/
└── main.c
```
`dcr.toml`:
```toml
[package]
name = "my-app"
version = "0.1.0"
type = "none"
[build]
language = "c"
standard = "c11"
compiler = "clang"
kind = "bin"
```
## Build
```bash
dcr build
```
Output — `target/<triple>/debug/my-app` (Linux) or `target/debug/my-app.exe` (Windows).
Build profiles:
```bash
dcr build --release # release build
dcr build --debug # debug (default)
```
## Run
```bash
dcr run
```
Builds (if needed) and runs the binary.
## First test
```bash
dcr test --init # create test template
dcr test # run tests
```
## Formatting
```bash
dcr fmt # clang-format with .clang-format
```
## Linting
```bash
dcr lint # clang-tidy checks
dcr lint --fix # apply fixes automatically
```
