+# DeepSeek Balance
+
+A lightweight VS Code extension that displays your current DeepSeek API balance directly in the status bar, along with real-time peak and off-peak status indicators.
+
+## Features
+
+- **Live API Balance:** View your current DeepSeek account balance at a glance.
+- **Peak / Off-Peak Indicator:** Real-time rate detection based on DeepSeek server schedules:
+  - **OFF-PEAK:** Green status text during discount hours.
+  - **PEAK:** Red status badge during standard pricing windows.
+- **Quick Dashboard Access:** Click the status bar item to open the DeepSeek Platform in your default browser and refresh your balance.
+- **Auto Refresh:** Periodically updates every 5 minutes automatically.
+
+## Requirements & Configuration
+
+To start fetching your balance, add your DeepSeek API key to your VS Code settings:
+
+1. Open VS Code Settings (`Ctrl+,` or `Cmd+,`).
+2. Search for `DeepSeek Balance`.
+3. Enter your API key under `DeepSeek Balance: Api Key`.
+
+Alternatively, add it directly to your `settings.json`:
+
+```json
+"deepseekBalance.apiKey": "sk-your-actual-api-key-here"
+```

+# Welcome to your VS Code Extension
+
+## What's in the folder
+
+* This folder contains all of the files necessary for your extension.
+* `package.json` - this is the manifest file in which you declare your extension and command.
+  * The sample plugin registers a command and defines its title and command name. With this information VS Code can show the command in the command palette. It doesn’t yet need to load the plugin.
+* `src/extension.ts` - this is the main file where you will provide the implementation of your command.
+  * The file exports one function, `activate`, which is called the very first time your extension is activated (in this case by executing the command). Inside the `activate` function we call `registerCommand`.
+  * We pass the function containing the implementation of the command as the second parameter to `registerCommand`.
+
+## Get up and running straight away
+
+* Press `F5` to open a new window with your extension loaded.
+* Run your command from the command palette by pressing (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and typing `Hello World`.
+* Set breakpoints in your code inside `src/extension.ts` to debug your extension.
+* Find output from your extension in the debug console.
+
+## Make changes
+
+* You can relaunch the extension from the debug toolbar after changing code in `src/extension.ts`.
+* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
+
+## Explore the API
+
+* You can open the full set of our API when you open the file `node_modules/@types/vscode/index.d.ts`.
+
+## Run tests
+
+* Install the [Extension Test Runner](https://marketplace.visualstudio.com/items?itemName=ms-vscode.extension-test-runner)
+* Run the "watch" task via the **Tasks: Run Task** command. Make sure this is running, or tests might not be discovered.
+* Open the Testing view from the activity bar and click the Run Test" button, or use the hotkey `Ctrl/Cmd + ; A`
+* See the output of the test result in the Test Results view.
+* Make changes to `src/test/extension.test.ts` or create new test files inside the `test` folder.
+  * The provided test runner will only consider files matching the name pattern `**.test.ts`.
+  * You can create folders inside the `test` folder to structure your tests any way you want.
+
+## Go further
+
+* [Follow UX guidelines](https://code.visualstudio.com/api/ux-guidelines/overview) to create extensions that seamlessly integrate with VS Code's native interface and patterns.
+* Reduce the extension size and improve the startup time by [bundling your extension](https://code.visualstudio.com/api/working-with-extensions/bundling-extension).
+* [Publish your extension](https://code.visualstudio.com/api/working-with-extensions/publishing-extension) on the VS Code extension marketplace.
+* Automate builds by setting up [Continuous Integration](https://code.visualstudio.com/api/working-with-extensions/continuous-integration).
+* Integrate to the [report issue](https://code.visualstudio.com/api/get-started/wrapping-up#issue-reporting) flow to get issue and feature requests reported by users.
