 # ImgBBApi
 
+A lightweight C# client library for uploading images to [ImgBB](https://imgbb.com/) from .NET applications.
+
+`ImgBBApi` accepts either local image file paths or Base64-encoded image data and returns the direct URLs generated by ImgBB.
+
+## Features
+
+- Upload one or more local image files
+- Upload Base64-encoded image content
+- Async API built on `HttpClient`
+- Multi-targets .NET 5, .NET 6, .NET 7, and .NET 8
+
+## Installation
+
+Install the package from NuGet:
+
+```bash
+dotnet add package Iminetsoft.ImgBBApi
+```
+
+Or use the NuGet Package Manager Console:
+
+```powershell
+Install-Package Iminetsoft.ImgBBApi
+```
+
+## Getting an ImgBB API key
+
+1. Sign in to [ImgBB](https://imgbb.com/).
+2. Create an API key from the [ImgBB API key page](https://api.imgbb.com/).
+3. Keep the key private—do not commit it to source control.
+
+For example, store it in an environment variable:
+
+```bash
+export IMGBB_API_KEY="your-api-key"
+```
+
+## How to use
+
+### Upload local files
+
+```csharp
+using System;
+using System.Collections.Generic;
+using Iminetsoft;
+
+var apiKey = Environment.GetEnvironmentVariable("IMGBB_API_KEY");
+var client = new ImgBBApi(apiKey);
+
+var imageUrls = await client.UploadImgbbAsync(new List<string>
+{
+    @"C:\\images\\photo-1.png",
+    @"C:\\images\\photo-2.jpg"
+});
+
+foreach (var imageUrl in imageUrls)
+{
+    Console.WriteLine(imageUrl);
+}
+```
+
+### Upload Base64 image data
+
+Pass a Base64-encoded image string instead of a file path:
+
+```csharp
+using System;
+using System.Collections.Generic;
+using System.IO;
+using Iminetsoft;
+
+var apiKey = Environment.GetEnvironmentVariable("IMGBB_API_KEY");
+var client = new ImgBBApi(apiKey);
+
+var base64Image = Convert.ToBase64String(
+    await File.ReadAllBytesAsync("photo.png"));
+
+var imageUrls = await client.UploadImgbbAsync(new List<string>
+{
+    base64Image
+});
+
+Console.WriteLine(imageUrls[0]);
+```
+
+## API reference
+
+### `ImgBBApi(string apiKey)`
+
+Creates a client with the ImgBB API key used for all upload requests.
+
+### `Task<List<string>> UploadImgbbAsync(List<string> imagePaths)`
+
+Uploads each supplied value to ImgBB and returns a list of image URLs.
+
+Each item may be:
+
+- a path to an existing local image file; or
+- a Base64-encoded image string.
+
+The returned list follows the successful upload order. If an upload fails, the current implementation suppresses the exception and may return an empty or partial list.
+
+## Requirements
+
+- .NET 5.0, 6.0, 7.0, or 8.0
+- A valid ImgBB API key
+- Internet access to `https://api.imgbb.com`
+
+## Notes
+
+- ImgBB controls its own upload limits, retention, and content policies. Consult the [ImgBB API documentation](https://api.imgbb.com/) for the current terms and limits.
+- Treat API keys and uploaded image URLs according to your application's security and privacy requirements.
