README documents commands but not the framework's underlying concepts.

In plain English

Specter is a TypeScript and Solid framework for building applications using a pattern called vertical slices and event sourcing. The README is brief and does not explain what those terms mean or what problems the framework is trying to solve, so the scope is unclear from the documentation alone. The repository is organized as a workspace containing four parts: the core framework package, a command-line initializer, a to-do app used as the default starter template, and a meeting-room booking app used as a second reference example. You can start a new project by running a single npm create command, which scaffolds a project based on the to-do template. The workspace includes standard commands for installing dependencies, building, type-checking, running tests, and starting a development server. Publishing a new release runs type checks, tests, and builds before uploading to the npm registry. The README provides no further detail about the framework's design, intended use cases, or how it compares to other approaches.
