-# create-svelte
+# Controller App
 
-Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/main/packages/create-svelte).
+This is the controller for my spot micro
-
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```bash
-# create a new project in the current directory
-npx sv create
-```
-
-## Developing
-
-Once you've created your project, follow these steps:
-
-1: Delete package-lock.json
-2: Check `git status`. If you see any changes other than package-lock.json or favicon.ico, run the command `git restore ./` (See below)
-3: Run `npm install` or `pnpm install` or `yarn` to install the dependencies
-4: Run `npm run build` to build the project
-
-Running `git status` should show:
-
-[![example.png](https://i.postimg.cc/yddM3hH3/example.png)](https://postimg.cc/7CFsp2bq)
-
-You can preview the production build with `npm run preview`.
-
-> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
