# Getting Started
This is a minimal setup for a crate that already has Cargo features and wants
checked, generated feature documentation.
## Install
```text
cargo install feature-manifest
```
That installs both entrypoints:
```text
cargo fm
cargo feature-manifest
```
## Initialize a Crate
From your crate root:
```text
cargo fm init --dry-run --ci
cargo fm init --ci
```
This scaffolds missing feature metadata, adds README markers, writes the current
feature table into that README section, and creates a GitHub Actions workflow.
The dry run shows the same setup plan without touching files.
## Fill in Metadata
Open `Cargo.toml` and replace generated TODO descriptions with real text:
```toml
[package.metadata.feature-manifest.features]
serde = { description = "Enable Serialize and Deserialize support.", category = "serialization" }
tokio = { description = "Enable Tokio-backed async APIs.", category = "runtime" }
```
## Validate
```text
cargo fm
```
Use `doctor` when you want to check project wiring too:
```text
cargo fm doctor --explain
```
Use strict doctor mode when warnings should fail CI:
```text
cargo fm doctor --strict
```
## Keep Docs Fresh
Regenerate the README section:
```text
cargo fm md -i README.md
```
Fail CI when it drifts:
```text
cargo fm md --check -i README.md
```
