# Guides

Task-focused how-tos for HTTP, data, background work, security, operations, integrations, and extending Zever.

Each guide solves one task: configure a battery, wire it through the container, and ship it. Guides assume you know the basics from the [quickstart](https://zenta-dev.github.io/zever/start/quickstart/). For the why, read [Concepts](https://zenta-dev.github.io/zever/concepts/how-zever-works/); for exact keys, see the [Config reference](https://zenta-dev.github.io/zever/reference/config/).

- [HTTP APIs](https://zenta-dev.github.io/zever/guides/http/routing/): Routing, middleware, CORS, validation, errors, codecs, sessions, and i18n.
- [Data and storage](https://zenta-dev.github.io/zever/guides/data/query-builder/): Query builder, migrations, cache, Redis, search, vector store, storage, and documents.
- [Background work](https://zenta-dev.github.io/zever/guides/background/overview/): Overview, queue, scheduler, events, outbox, workflows, saga, webhooks, mailer, and notifications.
