+# List of maintainers of the RT-Thread open-source community
+#
+# This file manages the maintainers and their associated sections in the repository.
+# Developers should update this file according to project needs.
+# The following are explanations of each field and guidelines for adding new maintainer entries.
+#
+# When adding new entries, please follow the format:
+#
+# 1. **tag** - Assign a unique tag to each entry for identifying the code module or functionality.
+#    - The tag should be concise and descriptive, such as `workflow`, `libc`...
+#    - **Rule for Adding**: Use a new tag when adding a new functionality or module to ensure it clearly describes the area of responsibility.
+#
+# 2. **path** - Specify the directory or file path that the maintainer is responsible for.
+#    - The path must be relative to the repository's root directory and can refer to either a single file or a folder.
+#    - If the maintainer is responsible for all files in a directory, use the directory path; if it's for a specific file, provide the full file path.
+#    - **Rule for Adding**: Ensure that the path correctly points to the relevant code location. Please note that a tag should correspond to only one path. Currently, multiple paths are not supported.
+#
+# 3. **owners** - List the maintainers responsible for the section, including their GitHub usernames and contact information.
+#    - The owners should be listed as a comma-separated list if there are multiple maintainers.
+#    - Format: `Name(GitHub username)<email address>`.
+#    - **Rule for Adding**: Ensure that the listed GitHub usernames are correct, and the maintainers are aware of their responsibilities and duties.
+#
+# Example: How to Add a Maintainer Entry
+#
+# The following is a template for adding new entries in the MAINTAINER file:
+#
+# tag: <module-name>
+# path: <file-or-directory-path>
+# owners: <maintainer1>, <maintainer2>, ...
+#
+# When adding entries, please follow these guidelines:
+# - Ensure the `tag` is unique and descriptive.
+# - Ensure the `path` points to the correct location in the repository.
+# - Ensure the `owners` are accurate and that all new maintainers are aware of their responsibilities.
+#
+# Example Entry:
+# tag: example-module
+# path: example/module/path
+# owners: John Doe(johndoe)<johndoe@example.com>, Jane Smith(janesmith)<janesmith@example.com>
+
+# Note: 
+# - Each entry includes a `tag` that identifies the module or functionality, a `path` that points to the relevant code location, and `owners` who are the maintainers for that part of the codebase.
+# - If there are multiple entries, each entry should be separated by a blank line. Within a single entry, there is no need to insert blank lines between the tag, path, and owners.
+
+# Below are existing maintainer entries, divided by module:
+
+tag: workflow
+path: .github
+owners: supper thomas(supperthomas)<78900636@qq.com>, Bingru Zhang(Rbb666)<751061401@qq.com>, Yuqiang Wang(kurisaW)<2053731441@qq.com>
