-## How to Use
 
-**To use this tool, you need to install Git(>=2.25.1) first.**
+## Thanks
 
-You can download the latest stable from [Releases](https://github.com/sourcegit-scm/sourcegit/releases/latest) or download workflow artifacts from [GitHub Actions](https://github.com/sourcegit-scm/sourcegit/actions) to try this app based on latest commits.
+* [PUMA](https://gitee.com/whgfu) 配置默认User
-
-This software creates a folder `$"{System.Environment.SpecialFolder.ApplicationData}/SourceGit"`, which is platform-dependent, to store user settings, downloaded avatars and crash logs.
-
-| OS      | PATH                                                |
-|---------|-----------------------------------------------------|
-| Windows | `%APPDATA%\SourceGit`                               |
-| Linux   | `${HOME}/.config/SourceGit` or `${HOME}/.sourcegit` |
-| macOS   | `${HOME}/Library/Application Support/SourceGit`     |
-
-> [!TIP]
-> * You can open this data storage directory from the main menu `Open Data Storage Directory`.
-> * You can create a `data` folder next to the `SourceGit` executable to force this app to store data (user settings, downloaded avatars and crash logs) into it (Portable-Mode). Only works on Windows.
-
-For **Windows** users:
-
-* **MSYS Git is NOT supported**. Please use official [Git for Windows](https://git-scm.com/download/win) instead.
-* You can install the latest stable from `winget` with follow commands:
-  ```shell
-  winget install SourceGit
-  ```
-> [!NOTE]
-> `winget` will install this software as a commandline tool. You need run `SourceGit` from console or `Win+R` at the first time. Then you can add it to the taskbar.
-* You can install the latest stable by `scoop` with follow commands:
-  ```shell
-  scoop bucket add extras
-  scoop install sourcegit
-  ```
-* Pre-built binaries can be found in [Releases](https://github.com/sourcegit-scm/sourcegit/releases/latest)
-
-For **macOS** users:
-
-* Thanks [@ybeapps](https://github.com/ybeapps) for making `SourceGit` available on `Homebrew`. You can simply install it with following command:
-  ```shell
-  brew tap ybeapps/homebrew-sourcegit
-  brew install --cask --no-quarantine sourcegit
-  ```
-* If you want to install `SourceGit.app` from GitHub Release manually, you need run following command to make sure it works:
-  ```shell
-  sudo xattr -cr /Applications/SourceGit.app
-  ```
-* Make sure [git-credential-manager](https://github.com/git-ecosystem/git-credential-manager/releases) is installed on your mac.
-* You can run `echo $PATH > ~/Library/Application\ Support/SourceGit/PATH` to generate a custom PATH env file to introduce `PATH` env to SourceGit.
-
-For **Linux** users:
-
-* Thanks [@aikawayataro](https://github.com/aikawayataro) for providing `rpm` and `deb` repositories, hosted on [Codeberg](https://codeberg.org/yataro/-/packages).
-
-  `deb` how to:
-  ```shell
-  curl https://codeberg.org/api/packages/yataro/debian/repository.key | sudo tee /etc/apt/keyrings/sourcegit.asc
-  echo "deb [signed-by=/etc/apt/keyrings/sourcegit.asc, arch=amd64,arm64] https://codeberg.org/api/packages/yataro/debian generic main" | sudo tee /etc/apt/sources.list.d/sourcegit.list
-  sudo apt update
-  sudo apt install sourcegit
-  ```
-
-  `rpm` how to:
-  ```shell
-  curl https://codeberg.org/api/packages/yataro/rpm.repo | sed -e 's/gpgcheck=1/gpgcheck=0/' > sourcegit.repo
-
-  # Fedora 41 and newer
-  sudo dnf config-manager addrepo --from-repofile=./sourcegit.repo
-  # Fedora 40 and earlier
-  sudo dnf config-manager --add-repo ./sourcegit.repo
-
-  sudo dnf install sourcegit
-  ```
-
-  If your distribution isn't using `dnf`, please refer to the documentation of your distribution on how to add an `rpm` repository.
-* `AppImage` files can be found on [AppImage hub](https://appimage.github.io/SourceGit/), `xdg-open` (`xdg-utils`) must be installed to support open native file manager.
-* Make sure [git-credential-manager](https://github.com/git-ecosystem/git-credential-manager/releases) is installed on your Linux.
-* Maybe you need to set environment variable `AVALONIA_SCREEN_SCALE_FACTORS`. See https://github.com/AvaloniaUI/Avalonia/wiki/Configuring-X11-per-monitor-DPI.
-* If you can NOT type accented characters, such as `ê`, `ó`, try to set the environment variable `AVALONIA_IM_MODULE` to `none`.
-
-## OpenAI
-
-This software supports using OpenAI or other AI service that has an OpenAI compatible HTTP API to generate commit message. You need configurate the service in `Preference` window.
-
-For `OpenAI`:
-
-* `Server` must be `https://api.openai.com/v1`
-
-For other AI service:
-
-* The `Server` should fill in a URL equivalent to OpenAI's `https://api.openai.com/v1`. For example, when using `Ollama`, it should be `http://localhost:11434/v1` instead of `http://localhost:11434/api/generate`
-* The `API Key` is optional that depends on the service
-
-## External Tools
-
-This app supports open repository in external tools listed in the table below.
-
-| Tool                          | Windows | macOS | Linux |
-|-------------------------------|---------|-------|-------|
-| Visual Studio Code            | YES     | YES   | YES   |
-| Visual Studio Code - Insiders | YES     | YES   | YES   |
-| VSCodium                      | YES     | YES   | YES   |
-| Fleet                         | YES     | YES   | YES   |
-| Sublime Text                  | YES     | YES   | YES   |
-| Zed                           | NO      | YES   | YES   |
-| Visual Studio                 | YES     | NO    | NO    |
-
-> [!NOTE]
-> This app will try to find those tools based on some pre-defined or expected locations automatically. If you are using one portable version of these tools, it will not be detected by this app.
-> To solve this problem you can add a file named `external_editors.json` in app data storage directory and provide the path directly. For example:
-```json
-{
-    "tools": {
-        "Visual Studio Code": "D:\\VSCode\\Code.exe"
-    }
-}
-```
-
-> [!NOTE]
-> This app also supports a lot of `JetBrains` IDEs, installing `JetBrains Toolbox` will help this app to find them.
