+
+### 🐛 Problem Description
+Provide a clear description of the issue. Include:
+- Library name and version (NuGet package or project)
+- Type of issue: compile-time / runtime / unexpected behavior
+- Short code snippet showing the context (optional, but helpful)
+
+---
+
+### 📝 Steps to Reproduce
+Provide a minimal, self-contained example:
+
+```csharp
+// Minimal reproducible example
+using MyLibrary;
+
+class Program
+{
+    static void Main()
+    {
+        var obj = new Foo();
+        obj.Bar(null); // Example of problematic call
+    }
+}
+````
+
+1. Which **class** and **method** did you call? What **parameters** did you pass?
+2. Operating system and .NET runtime version (e.g., Windows 11, .NET 8.0)
+3. How did you **install** and **reference** the library? (NuGet, version number, local reference, etc.)
+
+---
+
+### ✅ Expected Result
+
+Describe what the correct behavior should be.
+Example:
+
+* Method `Bar` should return a non-null string.
+* No exception should be thrown.
+
+---
+
+### 📄 Actual Result / Logs
+
+Include any errors, stack traces, or console output:
+
+```text
+System.NullReferenceException: Object reference not set to an instance of an object.
+   at MyLibrary.Foo.Bar(String input) in Foo.cs:line 42
+```
+
+---
+
+### ⚙ Additional Information
+
+* Is the library used in a multi-threaded environment?
+* Are there other libraries that might conflict?
+* Does the issue appear on specific hardware or OS versions?
+* Any workarounds tried?

+
+### 🔗 Is your feature request related to a specific issue?
+Please briefly describe the origin of this feature request. For example:  
+- The library is missing [specific feature], which causes [specific problem]  
+- You want to make certain scenarios easier by achieving [desired effect]
+
+---
+
+### 💡 Feature Description
+Explain in detail the feature you want to add or improve, including:  
+- Expected outcome or effect  
+- Specific implementation ideas, such as classes, methods, parameters, or API design  
+- Usage scenarios or benefits
+
+Example:  
+- Add `Foo.BarAsync()` method to allow asynchronous processing without blocking the main thread  
+- The goal is to improve performance and support multi-threaded environments
+
+---
+
+### ⚖ Alternatives Considered
+List other approaches you tried or considered, and explain why they are not ideal or feasible.  
+
+Example:  
+- Tried using an extension method `FooExtensions` for async, but encountered state management issues  
+- Existing approach only supports single-threaded scenarios and does not meet the requirements
+
+---
+
+### 📝 Additional Information
+Provide any extra background, design sketches, or code snippets to help developers better understand your idea.  
+- If it involves other game engines, you can attach editor screenshots or diagrams
