+# SIGTRAN.NET v0.1.0-alpha
+
+Date: 2026-06-27  
+Status: Alpha / Preview release preparation  
+Repository: https://github.com/araditc/sigtran.net
+
+## Overview
+
+SIGTRAN.NET v0.1.0-alpha is the first public alpha milestone for the project.
+
+SIGTRAN.NET is positioned as the first open-source .NET 10 SDK dedicated to SIGTRAN and SS7-over-IP protocol engineering. The project is intended to bring serious telecom signaling infrastructure to the modern .NET ecosystem.
+
+This release is aimed at early contributors, telecom protocol engineers, .NET developers, lab reviewers, and organizations interested in SIGTRAN, SS7-over-IP, M3UA, SCTP, SCCP, TCAP, and MAP.
+
+## What this alpha represents
+
+This alpha release track establishes the public project direction:
+
+- .NET 10 as the primary target.
+- M3UA as the first production-oriented milestone.
+- SCTP transport abstraction and Linux native SCTP direction.
+- SCCP, TCAP, and MAP foundations for future standards-oriented implementation.
+- Byte-level testing and protocol validation as core engineering principles.
+- Wireshark-friendly diagnostics and interoperability-oriented tooling.
+- Release governance, documentation, and package-readiness groundwork.
+
+## Intended audience
+
+This preview is intended for:
+
+- Telecom signaling engineers.
+- SS7/SIGTRAN specialists.
+- .NET and C# infrastructure developers.
+- Protocol testing and interoperability engineers.
+- Open-source contributors interested in telecom infrastructure.
+- Teams that can provide lab feedback, traces, validation vectors, or protocol review.
+
+## Contribution focus
+
+Contributions are welcome in code and non-code forms, including:
+
+- Protocol review.
+- M3UA validation.
+- SCTP testing on Linux.
+- SCCP, TCAP, and MAP standards alignment.
+- ASN.1 BER validation.
+- Wireshark trace comparison.
+- Interoperability lab results.
+- Documentation and examples.
+- Performance and memory-allocation review.
+- Issue reports and design discussions.
+
+## Production-readiness notice
+
+This is an alpha / preview milestone. It should not be treated as a production-ready telecom signaling stack.
+
+Production support should wait for:
+
+- Retained Linux SCTP verification evidence.
+- External SIGTRAN peer interoperability evidence.
+- Stable package publication evidence.
+- Stable API lifecycle validation.
+- Release, security, compliance, and operations review.

+```markdown
+SIGTRAN.NET v0.1.0-alpha is the first public alpha milestone for SIGTRAN.NET — the first open-source .NET 10 SDK dedicated to SIGTRAN and SS7-over-IP protocol engineering.
+
+This preview establishes the project direction around M3UA, SCTP transport abstraction, SCCP/TCAP/MAP foundations, byte-level protocol validation, Wireshark-friendly diagnostics, and an interoperability-focused roadmap.
+
+This release is intended for early contributors, telecom protocol engineers, .NET developers, and teams that can help with protocol review, lab validation, trace comparison, documentation, and interoperability feedback.
+
+This is an alpha release and is not yet production-ready. Production usage should wait for retained Linux SCTP verification evidence, external SIGTRAN peer interoperability evidence, stable package publication, and final release governance.
