+## About this fork
+
+This project is an **unofficial, independent fork** of Electrum, maintained by **Davide Grilli**.
+It adds first-class support for the **BitcoinPurple (BTCP)** network — a Bitcoin fork with
+1-minute blocks and a 120-block difficulty retarget window — while keeping full compatibility
+with the original Electrum codebase and all upstream bug fixes.
+
+This fork is **not affiliated with, endorsed by, or supported by** the original Electrum project
+or its developers. For the official Bitcoin wallet, use [electrum.org](https://electrum.org/).
+
+### What is different from upstream Electrum
+
+- `--bitcoinpurple` and `--bitcoinpurple_testnet` launch flags
+- BitcoinPurple chain parameters (1-min blocks, 120-block retarget, adjusted PoW limits)
+- Lightning Network timeouts scaled for 1-minute block times
+- Branding and packaging renamed to `electrum-purple` / `Electrum Purple`
+
+Everything else — wallet format, Lightning support, hardware wallets, plugins — is identical
+to upstream Electrum.
+
+### Licence and credits
+
+This software is released under the **MIT Licence**, the same licence as the original Electrum.
+All original copyright notices are preserved as required by the licence.

 ## Contributing
 
-Any help testing the software, reporting or fixing bugs, reviewing pull requests
-and recent changes, writing tests, or helping with outstanding issues is very welcome.
-Implementing new features, or improving/refactoring the codebase, is of course
-also welcome, but to avoid wasted effort, especially for larger changes,
-we encourage discussing these on the issue tracker or IRC first.
+Bug reports, testing, and pull requests for BitcoinPurple-specific features are welcome.
 
-Besides [GitHub](https://github.com/spesmilo/electrum),
-most communication about Electrum development happens on IRC, in the
-`#electrum` channel on Libera Chat. The easiest way to participate on IRC is
-with the web client, [web.libera.chat](https://web.libera.chat/#electrum).
+For issues unrelated to BitcoinPurple support (core wallet, Lightning, hardware wallets),
+please check the [upstream Electrum project](https://github.com/spesmilo/electrum) first —
+fixes merged upstream can be rebased into this fork.
 
-Please improve translations on [Crowdin](https://crowdin.com/project/electrum).
