## What Zelta Does

Zelta orchestrates ZFS snapshot replication across any modern Unix system. All operations
work recursively on dataset trees, locally or remotely over SSH. Zelta does not need to
be installed on remote hosts.

Core capabilities: `zelta backup`, `zelta snapshot`, `zelta match`, `zelta clone`,
`zelta revert`, `zelta rotate`, `zelta rebase`, `zelta failover`, `zelta lock`,
`zelta unlock`, `zelta propsync`, `zelta prune`, `zprune`, `zelta policy`.

## Quick Start for Agents

```sh
zelta help
zelta help options
zelta help backup
zelta backup -n SOURCE TARGET
```

Always use `-n` (dry-run) before changing ZFS state.

## Install

```sh
curl -fsSL https://raw.githubusercontent.com/bell-tower/zelta/release/bsdcan2026/contrib/install-from-git.sh | sh -s -- --branch=release/bsdcan2026
```
