+
+A Neovim plugin for creating predictions on [Fatebook](https://fatebook.io).
+
+## Features
+
+- Create predictions directly from Neovim with a simple command
+- Automatic date format conversion (DD-MM-YYYY)
+- Percentage-based forecasts (0-100)
+- Success/error notifications
+
+## Installation
+
+### LazyVim / lazy.nvim
+
+Add this to your LazyVim config (e.g., `~/.config/nvim/lua/plugins/fatebook.lua`):
+
+```lua
+return {
+  "f0ldspace/fatebook.nvim"
+  config = function()
+    require("fatebook").setup({
+      api_key = "your-api-key-here"
+    })
+  end,
+}
+```
+
+
+## Usage
+
+Use the `:Predict` command to create predictions:
+
+```vim
+:Predict "Will this work?", 55, 04-10-2025
+```
+
+### Format
+
+```vim
+:Predict "question", forecast, DD-MM-YYYY
+```
+
+- **Question**: Text in quotes (or without quotes if no commas in the question)
+- **Forecast**: Number between 0-100 (percentage probability)
+- **Date**: DD-MM-YYYY format (e.g., 31-12-2025)
