-# Inferable .NET Bootstrap
+# .NET Bootstrap for Inferable
 
-This is a .NET bootstrap application that demonstrates how to integrate and use our SDK. It serves as a reference implementation and starting point for .NET developers.
+[![NuGet version](https://img.shields.io/nuget/v/Inferable.svg)](https://www.nuget.org/packages/Inferable/)
+[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
+[![Documentation](https://img.shields.io/badge/docs-inferable.ai-brightgreen)](https://docs.inferable.ai/)
 
-## The Application
+This is a bootstrap project demonstrating how to create an Inferable service in .NET.
 
-The application is a simple .NET application that extracts the top posts from Hacker News and summarizes the comments for each post. It demonstrates how to:
+## Installation
 
-- Register C# functions with Inferable
-- Trigger a Run programmatically to orchestrate the functions
-- Control the control flow of the Run using native C# async/await primitives
+1. Clone this repository
+2. Install the Inferable NuGet package:
 
-```mermaid
-sequenceDiagram
-    participant extract
-    participant summarizePost
-    participant generatePage
+```bash
+dotnet add package Inferable
+```
+
+## Quick Start
+
+### Initializing the Client
+
+```csharp
+using Inferable;
 
-    extract->>extract: Get top 3 HN posts
-    extract->>summarizePost: Posts data
-    summarizePost->>summarizePost: Get & analyze comments
-    summarizePost->>generatePage: Summaries data
-    generatePage->>generatePage: Generate HTML
+var options = new InferableOptions
+{
+    ApiSecret = "your-api-secret", // Get yours at https://console.inferable.ai
+    BaseUrl = "https://api.inferable.ai" // Optional
+};
+
+var client = new InferableClient(options);
 ```
 
-## How to Run
+If you don't provide an API key or base URL, it will attempt to read them from the following environment variables:
 
-1. Start the local worker machine:
+- `INFERABLE_API_SECRET`
+- `INFERABLE_API_ENDPOINT`
 
-```bash
-dotnet run
+### Registering the Exec Function
+
+This bootstrap demonstrates registering a secure command execution [function](https://docs.inferable.ai/pages/functions):
+
+```csharp
+public class ExecInput
+{
+    [JsonPropertyName("command")]
+    public string Command { get; set; }  // Only "ls" or "cat" allowed
+
+    [JsonPropertyName("arg")]
+    public string Arg { get; set; }      // Must start with "./"
+}
+
+client.Default.RegisterFunction(new FunctionRegistration<ExecInput> {
+    Name = "exec",
+    Description = "Executes a system command (only 'ls' and 'cat' are allowed)",
+    Func = new Func<ExecInput, object?>(ExecService.Exec),
+});
+
+await client.Default.StartAsync();
 ```
 
-2. Trigger the HN extraction:
+### Using the Function
+
+The exec function can be called through Inferable to execute safe system commands:
 
 ```bash
-dotnet run run
+ls ./src           # Lists contents of ./src directory
+cat ./README.md    # Shows contents of README.md
 ```
 
-## How it works
+The function returns:
+
+```csharp
+public class ExecResponse
+{
+    public string Stdout { get; set; }    // Command output
+    public string Stderr { get; set; }    // Error output if any
+    public string Error { get; set; }     // Exception message if failed
+}
+```
+
+### Security Features
+
+This bootstrap implements several security measures:
+
+- Whitelist of allowed commands (`ls` and `cat` only)
+- Path validation (only allows paths starting with `./`)
+- Safe process execution settings
+- Full error capture and reporting
 
-1. The worker machine uses the Inferable .NET SDK to register functions with Inferable. These functions are registered in the `Register.cs` file:
+## Documentation
 
-- `GetUrlContent`: Fetches the content of a URL and strips HTML tags
-- `ScoreHNPost`: Scores a Hacker News post based on upvotes and comment count
-- `GeneratePage`: Generates an HTML page from markdown
+- [Inferable Documentation](https://docs.inferable.ai/)
+- [.NET SDK Documentation](https://docs.inferable.ai/dotnet)
 
-2. The `Run.cs` script defines three main operations that are orchestrated by Inferable:
+## Support
 
-- `extract`: Extracts and scores the top 10 HN posts, selecting the top 3
-- `summarizePost`: Summarizes the comments for each selected post
-- `generatePage`: Generates an HTML page containing the summaries
+For support or questions, please [create an issue in the repository](https://github.com/inferablehq/inferable/issues).
 
-3. The application flow:
+## Contributing
 
-- The extract operation fetches the top posts from Hacker News and scores them using internal scoring logic
-- For each selected post, a separate summarization run analyzes the comments
-- Finally, the generate operation creates an HTML page containing all the summaries
+Contributions to the Inferable .NET Bootstrap are welcome. Please ensure that your code adheres to the existing style and includes appropriate tests.
 
-4. The application uses C# primitives for control flow:
+## License
 
-- Async/await for non-blocking operations
-- Strong typing with C# records and classes
-- Reflection for inferring the function signatures and result schema
+MIT
