+# LeetCode.nvim Guide: Solve LeetCode Problems in Neovim
+
+LeetCode.nvim is a powerful plugin that integrates LeetCode directly into your Neovim editor, allowing you to browse, solve, and submit LeetCode problems without leaving your favorite editor.
+
+## Getting Started
+
+1. Open the LeetCode interface with command:
+
+   ```
+   :Leet
+   ```
+
+2. You'll need to log in to your LeetCode account the first time you run it.
+
+## Basic Commands
+
+- `:Leet` - Opens the main LeetCode menu
+- `:Leet daily` - Open today's daily challenge
+- `:Leet random` - Get a random problem
+- `:Leet list` - Browse all problems
+- `:Leet tabs` - Switch between open problems
+- `:Leet submit` - Submit current solution
+- `:Leet run` - Run current solution with test cases
+- `:Leet reset` - Reset the code to default template
+- `:Leet lang` - Change programming language for current problem
+- `:Leet cookie update` - Update your LeetCode cookie
+
+## Filter Problems
+
+When using `:Leet list` or `:Leet random`, you can filter problems:
+
+- By difficulty: `difficulty=easy/medium/hard`
+- By status: `status=ac/notac/todo`
+- By tags: `tags=array,string,dp`
+
+Example:
+
+```
+:Leet list difficulty=medium status=notac
+:Leet random status=todo difficulty=hard
+```
+
+## Keybindings Within LeetCode UI
+
+These keys only work within the LeetCode interface and won't conflict with your existing keymaps:
+
+- `q` - Toggle/close panels
+- `<CR>` (Enter) - Confirm selection
+- `r` - Reset test cases
+- `U` - Use a custom test case
+- `H` - Focus on test cases panel
+- `L` - Focus on results panel
+
+## Tips for Use
+
+1. **Switch Languages**: Use `:Leet lang` to change your programming language for the current problem.
+
+2. **Multiple Problems**: You can have multiple LeetCode problems open in different tabs.
+
+3. **Code Auto-Injection**: Useful imports and boilerplate code are automatically added for common languages.
+
+4. **Description Format**: Problem descriptions are formatted for better readability, including proper markdown rendering.
+
+5. **Efficient Workflow**: LeetCode.nvim caches your progress, making it faster to get back to your problems.
+
+Enjoy solving LeetCode problems without leaving your favorite editor!
