+The IOCX CLI provides a fast, script‑friendly interface for extracting Indicators of Compromise (IOCs) from text, logs, binaries, and PE files. It wraps the same engine used by the Python API and exposes a clean, minimal set of options suitable for both interactive use and automation.
 
 ## Installation
-```bash
 
+```bash
 pip install iocx
-
 ```
 
 After installation, the `iocx` command becomes available on your system.
 
 ## Basic Usage
 
-Extract IOCs from a file or raw text:
-```bash
+Extract IOCs from raw text:
 
+```bash
 iocx "Suspicious domain: evil.com"
-

 Extract from a file:

+```bash
+iocx sample.exe
 ```
 
 Read from stdin:
-```bash
 
+```bash
 echo "visit http://malicious.com" | iocx -
-
 ```
 
 ## Command‑Line Options
 
-The CLI supports a focused set of flags designed to keep the interface simple while still offering meaningful control.

+# Threat Model Overview
+
+The following diagrams illustrate the IOCX security model, focusing on how untrusted data flows through the system and where potential threats may arise. IOCX is designed to process hostile input safely, so understanding these boundaries helps clarify the project’s defensive posture.
+
+IOCX operates as a static extraction tool: it does not execute binaries, load external code, or perform dynamic analysis. The attack surface is intentionally small, with strict parsing, minimal dependencies, and no network access.
+
+## Data-Flow Diagram (DFD)
+
+This diagram shows the major components involved when IOCX processes untrusted input. It highlights the trust boundaries between the user environment, the IOCX engine, and the untrusted data being analysed.
+
+- **User Environment** represents the analyst invoking the CLI.
+- **Untrusted Input** includes any file provided to IOCX—text, logs, binaries, or potentially malicious samples.
+- **IOCX Engine** contains the detectors, parsers, and supporting components that operate on the input.
+
+Threat indicators show where malformed or malicious content may attempt to influence the system.

+## STRIDE‑Oriented Threat Interaction Diagram
+
+This diagram expands the model to include an explicit attacker. It illustrates how an adversary might attempt to exploit the system by supplying malformed binaries, abusing parsers, or attempting to bypass detectors.
+
+The diagram also shows the flow of data through the CLI, engine, and output stages, making it clear where IOCX must remain defensive.
+
+Key points:
+
+- Attackers interact **only** through untrusted input files.
+- IOCX performs **no dynamic execution**, reducing risk.
+- All parsing is done in user space with strict error handling.
+- Output is deterministic JSON with no side effects.

+## How These Diagrams Fit Into IOCX’s Security Posture
+
+These diagrams support the project’s security goals by:
+
+- Defining clear trust boundaries
+- Identifying where untrusted data enters the system
+- Highlighting components that must be hardened
+- Demonstrating that IOCX avoids high‑risk behaviours (execution, deserialization, network access)
+- Providing transparency for auditors, contributors, and users
+
+Together, they form the foundation of IOCX’s threat model and help guide secure development practices.

 ## Project Philosophy
 
 IOCX is intentionally:
 
-- Minimal — very small dependency footprint
+- Minimal — extremely small dependency footprint
 - Secure — safe handling of untrusted input
-- Predictable — deterministic behaviour, no network access
-- Extensible — new extractors and static‑analysis modules can be added cleanly
+- Deterministic — no network access, no non-deterministic behaviour

 All contributions must align with these principles.
 
 ## Core vs Plugins
 
-IOCX is built around a clear separation between core functionality and plugin‑based extensions. This boundary keeps the project focused and deterministic while allowing contributors to extend it safely.
