+# Installation
+
+## Requirements
+
+| | |
+|---|---|
+| **Electrum** | {{ bal.electrum_latest }} (last stable release tested) |
+| **Platform** | Desktop — Linux, Windows, macOS |
+| **License** | MIT |
+| **Wallet type** | Standard seed-based single-signature, or a [hardware wallet](../user-guide/hardware-wallets.md). See [Compatibility](../user-guide/compatibility.md). |
+
+Install Electrum first, from the official site [electrum.org](https://electrum.org), and verify its signature as you normally would.
+
+## 1. Download the plugin
+
+Get the latest release from the [plugin releases page](https://bitcoin-after.life/gitea/bitcoinafterlife/bal-electrum-plugin/releases).
+
+!!! tip "Verify the archive"
+    Check that the zip's SHA-256 matches the value printed by `build_zip.py`. If you built the zip yourself from source, compare it against the published release.
+
+## 2. Install it in Electrum

+![Plugin list with Bitcoin After Life enabled](../img/install-plugin-enabled.png){ .screenshot }
+*The plugin enabled and ready.*
+
+## 4. Check that it loaded
+
+After restarting you will see two new tabs in the Electrum window: **HEIRS** and **WILL**.
+
+![Electrum with the HEIRS and WILL tabs](../img/overview-tabs.png){ .screenshot }
+*HEIRS is where you define who inherits; WILL shows the technical state of your inheritance transactions.*
+
+Next: [create your first will](quick-start.md).
