 # Hyperlight Sandbox
 
 A multi-backend sandboxing framework for running untrusted code with controlled host capabilities. Built on [Hyperlight](https://github.com/hyperlight-dev/hyperlight).
 
+Supported backends:
+
+- [Wasm Component Sandbox](#wasm-component-sandbox) (Python/Javascript or provide your own)
+- [HyperlightJS Sandbox](#hyperlightjs-sandbox)
+- [Nanvix Sandbox](#nanvix-sandbox)
+
 ## Overview
 
-hyperlight-sandbox provides a unified API across multiple isolation backends. All backends share a common capability model.  A python SDK is provided.

-- **Secure code execution** -- Run untrusted code in isolated sandboxes
+- **Secure code execution** -- Run untrusted code in hardware isolated sandboxes (KVM, MSHV, Hyper-v)
 - **Host tool dispatch** -- Register callables as tools; guest code invokes them by name with schema-validated arguments
-- **Capability-based file I/O** -- Read-only `/input` directory, writable `/output` directory, strict path isolation
-- **Snapshot / restore** -- Capture and rewind sandbox runtime state
-- **Network allowlisting** -- Outbound HTTP is deny-by-default; allow specific domains and methods with `allow_domain()`
+- **Capability-based file access** -- Read-only `/input` directory, writable `/output` directory, strict path isolation
+- **Snapshot / restore** -- Capture and rewind sandbox runtime state making it re-useable
+- **Network allow listing** -- Network traffix is off by default; allow specific domains and HTTP verbs with `allow_domain()`

 ### Use Cases
 
-- **File Processing**: Process provided files in Python and return a summarized report
+- **File Processing**: Process provided files and return a summarized report
 - **Code Mode**: Let an agent write a script that calls your tools directly, reducing token usage
-- **Sandboxed Execution** as a library: drop into an existing app or library without building a custom runtime
+- **Sandboxed Execution as a library**: drop into an existing app or library to provide plugins 
 - **Agent Skills** combine scripts into multi-step workflows that run in isolation (future work)

 ### Wasm Component Sandbox
 
-Loads a Wasm component via [hyperlight-wasm](https://github.com/jsturtevant/hyperlight-wasm) and exposes the full capability surface through WIT-generated bindings. Supports the packaged Python guest and JavaScript guest. Use this for general-purpose workloads that need tools, file I/O, networking, and snapshots.

+Build your own using the provided [WIT interface](src/wasm_sandbox/wit/hyperlight-sandbox.wit). See the [python](./src/wasm_sandbox/guests/python/) and [javascript](./src/wasm_sandbox/guests/javascript/) guests for examples.

 ### HyperlightJS Sandbox
 
-Runs JavaScript directly on the [HyperlightJS](https://github.com/hyperlight-dev/hyperlight-js) runtime without going through the Wasm component model. Injects `call_tool`, `read_file`, `write_file`, and `fetch` as globals. Supports snapshots, file I/O, and network allowlists. A simpler runtime path when the workload is JavaScript-only.
