Clarification needed on custom theme usage with MantineProvider

[artemchs]

Reproduction

I've created a minimal repository that demonstrates this issue: next-app-mantine-tailwind-template-issue

Steps to reproduce:

1. Clone the repository
2. Install dependencies (pnpm install)
3. Check the TypeScript error in src/app/layout.tsx on line 50

Description

There seems to be a disconnect between the documentation for custom theme usage and how it should be implemented with MantineProvider. The current documentation shows how to configure the Tailwind preset with a custom Mantine theme, but it's not clear how this should work with MantineProvider.

Current Behavior

Following the documentation, I created a theme configuration like this:

// theme.ts
import tailwindPresetMantine from "tailwind-preset-mantine";
import { createTheme } from "@mantine/core";

const mantineTheme = createTheme({
  // custom theme options
});

const themeConfig = {
  presets: [
    tailwindPresetMantine({
      mantineColors: mantineTheme.colors,
      mantineBreakpoints: mantineTheme.breakpoints,
    }),
  ],
};

export default themeConfig;

However, when trying to use this configuration with MantineProvider:

<MantineProvider theme={themeConfig}>{children}</MantineProvider>

I get the following TypeScript error:

Type '{ presets: Config[]; }' has no properties in common with type 'PartialObjectDeep<MantineTheme, {}>'.ts(2559)

Expected Behavior

I expect to be able to use my custom theme with MantineProvider without any type issues.

Environment

• tailwind-preset-mantine version: [^1.2.1]
• @mantine/core version: [^7.13.4]
• Next.js version: [^15.0.1]

Hi there! It looks like there might be a little misunderstanding in how to use it.

I've made some updates to the template to include the custom theme code in this commit.

Please take a look, and let me know if you have any questions!

Thank you for clarifications. Yes, not it works as expected with no type issues.

I've also updated the docs to make it more clear for custom themes:
