-Official PHP server SDK for the [SeatLayer](https://seatlayer.io) reserved-seating API.
+The official SeatLayer PHP server SDK — the trusted side of a reserved-seating
+integration. Inspect what a hold really contains, price from server-owned seating-chart
+data, and book with a stable `bookingRef`, while managing charts, events, inventory,
+allocations, and webhooks through one typed ticketing API client.

+## Frequently asked questions
+
+### How do I book seats from PHP?
+
+Create a client with your secret key, obtain a hold id — either from the buyer's
+browser session or by holding server-side — and call `$seatlayer->inventory->book($eventKey, holdId: ..., bookingRef: ...)`.
+`bookingRef` is your own stable order id and is the join between SeatLayer
+inventory and your commercial order, so the same reference identifies the booking
+in Booking History and when you later cancel it. For phone orders, box office, and
+comps, `$seatlayer->inventory->bookBestAvailable(...)` books outright with no browser involved.
+
+### What does the server SDK do compared with the buyer SDK?
+
+The buyer SDK runs where the ticket buyer is: it renders the interactive seating
+chart, handles seat selection, and creates temporary holds. This server SDK is the
+trusted side. It authenticates with your secret key, inspects what a hold actually
+contains, prices from server-owned data, and books. Never bundle the secret key
+into a browser or a mobile app — browser surfaces get short-lived, origin-bound
+tokens that you mint here.
+
+### How do temporary holds work server-side?
+
+A hold reserves seats against concurrent buyers for a limited window.
+`$seatlayer->inventory->retrieveHold($eventKey, $holdId)` is the authoritative answer for what is held
+and at what price, so charge from its `items` rather than from anything the browser
+sent you. When an order runs longer than the checkout window, `$seatlayer->inventory->extendHold(...)`
+renews the hold instead of releasing and re-holding, which would hand the seats to
+whoever is racing for them. Bookings carry the server's exact-selection plus
+`bookingRef` safeguard, but the SDK sends each booking once — reconcile an unknown
+outcome before trying again.
+
+### Can I use my own payment provider?
+
+Yes. SeatLayer never processes payment. Inspect the hold, compute the charge from
+the returned `items` and their authoritative `unitPrice` and `currency`, take the
+money through whichever provider you already use — Stripe, Adyen, Razorpay, or your
+own — and then book the hold with your order id as `bookingRef`. SeatLayer owns
+seating state, holds, booking concurrency, and the inventory ledger; your platform
+owns payments, commercial orders, tickets, delivery, and refunds.
