+# Uploading Images to Cloudinary with the .NET SDK
+
+## 🧰 Uploading with the SDK in a .NET project
+
+To use the SDK in a .NET project, first install the SDK:
+
+```sh
+dotnet add package CloudinaryDotNet
+```
+Then, add the necessary package reference
+
+```csharp
+using CloudinaryDotNet;
+using CloudinaryDotNet.Actions;
+```
+
+Finally, configure a new instance of Cloudinary:
+
+```csharp
+Account account = new Account(
+ "<Your Cloud Name>",
+ "<Your API Key>",
+ "<Your API Secret>");
+
+Cloudinary cloudinary = new Cloudinary(account);
+```
+
+Finally, run the upload method, passing in your image source:
+
+```csharp
+var uploadParams = new ImageUploadParams()
+{
+ File = new FileDescription("<Image Location or URL>")
+};
+var uploadResult = await cloudinary.UploadAsync(uploadParams);
+```
+
+## 🚀 Get Started with This Example
+
+* Add the following environment variables via your shell
+```sh
+# In Bash
+export CLOUDINARY_CLOUD_NAME=<Your Cloud Name>
+export CLOUDINARY_API_KEY=<Your API Key>
+export CLOUDINARY_API_SECRET=<Your API Secret>
+
+# Or
+
+# In CMD
+set CLOUDINARY_CLOUD_NAME="<Your Cloud Name>"
+set CLOUDINARY_API_KEY="<Your API Key>"
+set CLOUDINARY_API_SECRET="<Your API Secret>"
+```
+
+* Install the project dependencies with:
+
+```sh
+dotnet restore
+```
+
+* Run the program with:
+
+```sh
+dotnet run
+```
+
+The program will run in your terminal and you'll see the URL results logged.
