-Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/master/packages/create-svelte).
+/!\ work in progress!

-If you're seeing this, you've probably already done this step. Congrats!
+Anvil is a web client app for interacting with federated forges. It's meant to
+allow you to:
 
-```bash
-# create a new project in the current directory
-npm create svelte@latest
+- Create an account of a federated forge
+- Browse software projects
+- Create and manage your software projects
+- Create and manage teams and organizations
+- Participate and interact with software projects: Repo, issues, PRs, CI, etc.
+  etc.
 
-# create a new project in my-app
-npm create svelte@latest my-app
-```
+It's meant to be deployed in 3 ways:
+
+1. [Tauri](https://tauri.app) app, packaged with Flatpak, that you can install
+   on your desktop
+2. Independent fully-client-side hosted app you can access using a web browser
+   and connect to any forge (we will probably host one on Anvil's website for
+   convenient reachout, but anyone can host on their server)
+3. Hosted app served by federated forge servers as their default UI, in
+   multi-page mode and pre-rendered pages
+
+Status (May 2023): Implementation is in very early initial stages.
+
+Tech stack:
+
+- SvelteKit
+- TypeScript
+- Tailwind
+- Skeleton.dev
+
+Soon also:
+
+- Tauri
+- ActivityPub
+- ForgeFed
 
 ## Developing
 
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+Install NodeJS. Recommended method: [FNM](https://github.com/Schniz/fnm).
+
+Install dependencies:
+
+```bash
+npm install

+Launch development server:
 
 ```bash
