 ### A friendly application manager and task runner for React.js

 There are a lot of "meta" skills around React web development that don't really have anything to do with building great web products.
 
 For example, the terminal. For those of us who didn't grow up on a unix shell, the terminal is an inscrutable box of cryptic and indecipherable commands. It's undoubtedly powerful, and a valuable skill to develop... but should it really be a pre-requisite for modern web development?

+Guppy is a free-to-use desktop application designed to make it easier to get started building React web products. It provides a friendly GUI for many of the typical tasks facing React developers:
 
 - Creating new projects
 - Running a development server
 - Executing tasks (building for production, running tests, ...)
 - Managing dependencies (adding, updating, searching)
 
-Guppy is made for beginners - folks who are just starting out with web development. We hope that it's powerful enough for advanced users as well, but we'll always prioritize the new-developer experience.

+### How it works
+
+Guppy is an electron application that secretly runs terminal commands for you in the background. It uses **create-react-app** and **gatsby-cli**. Support could conceivably be added for Next, and other project types (including non-React ones)
+
+Guppy adds a new top-level key to your `package.json` to store project-related information. It also reads from `package.json` to figure out the current dependencies, and see which tasks are available (via `scripts`).
+
+Guppy has intelligent modules built around task types. For example, the dev server is no ordinary task, it's one that ought to be running throughout your time working on the project, and so it's given its own module at the top of the page.

 ### Future Vision
 
 Right now, Guppy's feature-set is pretty limited. It consists of 3 modules: a "dev-server" pane, a "tasks" pane, and a "dependencies" pane.

 - Dependencies should be easy to update. I imagine an "update core dependencies" button that updates react, react-dom, and any associated packages, with built-in codemod support. I imagine it being able to find security problems (via [`npm audit`](https://docs.npmjs.com/getting-started/running-a-security-audit)).
 
 I'd also like to see Guppy become far more useful for educating users about web development. The philosophy of Guppy is that anybody can learn web development, and it should provide resources to help learners along. Guppy has full access to the project code and settings, and so I wonder if there are opportunities to suggest solutions to problems the user runs into... I don't have any concrete ideas yet, but it's interesting to think about.
