# Installation

> Install SendyKit alongside your existing Sendy deployment

## Installation model

SendyKit installs **next to** Sendy. It does not patch Sendy core files.

That means:

* your licensed Sendy install stays where it is
* SendyKit reads the same database
* SendyKit adds its own `sendykit_*` tables
* if SendyKit stops, Sendy still works

## Before you install

You should have:

* a working Sendy install
* shell access to the server
* Sendy database credentials
* a SendyKit license key for self-hosted installs

## Install command

```bash theme={null}
curl -sSL https://install.sendykit.dev | bash
```

The installer should:

* detect OS and architecture
* download the correct binary
* prompt for license details
* create initial config

## First boot sequence

```bash theme={null}
sendykit migrate
sendykit serve
```

## What migrations do

SendyKit migrations are versioned and non-destructive.

They create SendyKit-owned tables such as:

* `sendykit_migrations`
* `sendykit_feature_flags`
* `sendykit_webhooks`
* `sendykit_analytics_events`
* `sendykit_doctor_reports`
* `sendykit_audit_log`

They do **not** modify Sendy core tables.

## Verify the install

```bash theme={null}
sendykit health
sendykit doctor
sendykit brands list
```

If those work, you have the main operator surfaces connected.
