-<hr>
+REDasm is a disassembler and binary analysis tool for Windows and Linux,
+built for both hobbyists and professional reverse engineers.  
+It supports various CPU architectures and executable formats
+(see [Supported Formats and Architectures](#supported-formats-and-architectures)).  
+It also offers an interactive listing, control flow graph view, cross-references, string detection and automatic
+function recovery.
 
-A free and open source disassembler designed for both hobbyists and professional reverse engineers.  
-Built on a solid, extensible core with a plugin architecture, REDasm supports multiple CPU architectures and executable formats.  
-  
-<h5 align="center">
-Version 4 is currently in active development and introduces a completely redesigned foundation
-</h5>
+REDasm is released under GPL-3.0 license, and every plugin ships as open source.

+
+## Design Principles
+
+- **Open by default**: GPL core & plugins, public C API. Everything can be read,
+  modified and rebuilt.
+- **Native, self-contained core**: [libredasm](https://github.com/redasm-dev/core) is written in C17 and 
+  doesn't depends on VM, runtime or interpreter. 
+- **No platform lock-in**: Windows and Linux are what's actively developed and tested;
+  support for other platforms is open to anyone willing to contribute the changes they need.
+- **Extendable**: plugins are shared libraries loaded at runtime. Adding a CPU architecture or a file format 
+  never requires touching the core.
+- **First class native GUI**: written with Qt6 and sits entirely above core API. The interactive listing, 
+  graph view and navigation are designed together with the engine, not layered on afterwards.
+- **First class support for retro and legacy formats**: DOS, Win16, OS/2 era and console binaries are part of REDasm experience.
+  This is what makes software preservation, recovery and porting possible for binaries whose source code is long gone.
+
+## Features
+
+- Interactive **disassembly listing** with renaming, commenting and typed data.
+- **Control flow graph** view at function granularity, synchronized with the listing.
+- **Cross-references** for code and data, with navigable history.
+- **RDIL**, a minimal, architecture-neutral, intermediate language used for analysis and lifting.
+- Automatic **string detection** (ASCII, UTF-16 and Latin-1 wide strings).
+- **Type system** with structs, unions, enums and typedefs, applied directly to the listing.
+- Integrated **hex view**.
+- **Segments**, imports/exports, symbols, strings and problems panels.
+- **Project save/load** so analysis, renames and comments survive between sessions.
+- **Patching** and export of analysis data.
+- Light and dark **themes**.

+
+## Download
+
+Pre-built binaries are published on the [Releases page](https://github.com/redasm-dev/redasm/releases):
+
+- **Linux**: AppImage, runs on any reasonably recent distribution.
+- **Windows**: portable build, no installation required.
+
+Nightly builds are produced automatically from `master` and are GPG signed.  
+They track development closely and **may be unstable**.
+
+---
+
+## Building from Source
+
+REDasm is split across several repositories: the [workspace](https://github.com/redasm-dev/workspace) repo fetches and builds all of them together.  
+Requirements, build steps and version pinning are documented in the
+[workspace README](https://github.com/redasm-dev/workspace).
+
+## Contributing
+
+Bug reports, feature requests and pull requests are welcome.   
+All reports are now centralized at [in a dedicated repo](https://github.com/redasm-dev/bugs), so report there regardless of which component the problem
+belongs to, whether it's the GUI, the core or a plugin.
+
+## FAQ
+
+**Is REDasm free?**  
+Yes. The whole project is GPL-3.0, including every bundled plugin.  
+You can use it, study it, modify it
+and redistribute it under the terms of the license.
+
+**Does REDasm have a decompiler?**  
+Not yet. The foundations like RDIL, function boundaries, basic blocks, the type system are already in
+place, but decompilation is a long-term goal, some important features are still missing.
+
+**Which platforms are supported?**  
+Windows and Linux.  
+Those are the platforms that can be actively tested, so they are the ones that get support.  
+Nothing in the codebase is tied to them, though, if you need REDasm on another platform, 
+open an issue or send the changes required, and support can be extended from there.
+
+**Can I script REDasm?**  
+A Python plugin API is on the roadmap.  
+Today, extensions are written in C.
+
+**Can I run REDasm headless as library?**  
+Yes, this repo contains only the GUI, it's still the main repo for historical reasons.  
+REDasm engine lives in [core](https://github.com/redasm-dev/core) repo and contains what's needed
+to analyze binaries and load plugins.
+
+**What happened to version 3?**  
+Retired because of technical debt and engine limitations, version 4 is a complete rewrite 
+written in plain C with a more powerful and fast analysis engine.
