Deciding whether to use Wow

1. Why Wow: what it does, the principles, what it assumes, and when it is not the right tool.
2. Quickstart: one service from an empty project to a command sent and its state read, in about thirty minutes.
3. Concepts: the log, the write path, subscriptions, read models and the contract.
4. Tutorial: two contexts working together, from a basket to an order.

Building a service in Kotlin or Java

1. Quickstart, or Add Wow to an Existing Service.
2. Guide: aggregates and rejections, sagas, projections, reading and querying, calling other services, testing, and the Spring Boot host.
3. Agent Skills: the wow-develop Skill writes, reviews and diagnoses with you.

Calling a service from TypeScript

1. TypeScript: the packages and what each one does.
2. Generate a Client, Send Commands, Read and Query.
3. View Engine, for views users configure.

Running Wow in production

1. Running Wow: what a deployment is made of.
2. Deployment Model, Configure a Service, Kubernetes.
3. Health, Metrics and Tracing, Troubleshooting, The Ops Service and Console.

Analyzing the data

1. Data in a Wow System: the three models a query reads.
2. Query for Analysis, then the Query Language.
3. Datasets and the Analytics Catalog, The Workbench.

Moving from 9.x

1. Migrating from 9.x: what changes and the way across.
2. 9.x Capabilities in V10, then Migrate the Source.
3. Migrate the Data and Cut Over.

Contributing to Wow itself starts with Codebase Tour.
