+A modular PySide6(Qt6) toolkit for [BEC (Beamline Experiment Control)](https://github.com/bec-project/bec). Create
+high-performance, dockable GUIs to move devices, run scans, and stream live or disk data—powered by Redis and a modular
+plugin system.
 
-**⚠️ Important Notice:**
+## Highlights
 
-🚨 **PyQt6 is no longer supported** due to incompatibilities with Qt Designer. Please use **PySide6** instead. 🚨
+- **No-code first** — For ~90% of day-to-day workflows, you can compose, operate, and save workspaces **without writing
+  a single line of code**. Just launch, drag widgets, and do your experiment.
+- **Flexible layout composition** — Build complex experiment GUIs in seconds with the `BECDockArea`: drag‑dock, tab,
+  split, and export profiles/workspaces for reuse.
+- **CLI / scripting** — Control your beamline experiment from the command line a robust RPC layer using
+  `BECIPythonClient`.
+- **Designer integration** — Use Qt Designer plugins to drop BEC widgets next to any Qt control, then launch the `.ui`
+  with the custom BEC loader for a zero‑glue workflow.
+- **Operational integration** — Widgets stay in sync with your running BEC/Redis as the single source of truth:
+  Subscribe to events from BEC and create dynamically updating UIs. BECWidgets also grants you easy access the
+  acquisition history.
+- **Extensible by design** — Build new widgets with minimal boilerplate using `BECWidget` and `BECDispatcher` for BEC data and
+  messaging. Use the generator command to scaffold RPC interfaces and Designer plugin stubs; beamline plugins can extend
+  or override behavior as needed.
 
-BEC Widgets is a GUI framework designed for interaction with [BEC (Beamline Experiment Control)](https://gitlab.psi.ch/bec/bec).

 ## Installation
 
+Use any of the following setups:
+
+### Stable release
+
 Use the package manager [pip](https://pip.pypa.io/en/stable/) to install BEC Widgets:
 
 ```bash
-pip install bec_widgets[pyside6]
+pip install bec_widgets
 ```
 
+### From source (recommended for development)
+
 For development purposes, you can clone the repository and install the package locally in editable mode:
 
 ```bash
-git clone https://gitlab.psi.ch/bec/bec-widgets
+git clone https://github.com/bec-project/bec_widgets.git
 cd bec_widgets
-pip install -e .[dev,pyside6]
+pip install -e .[dev]
 ```
 
-BEC Widgets now **only supports PySide6**. Users must manually install PySide6 as no default Qt distribution is
-specified.
+## Features
+
+### 1. Dock area interface: build GUIs in seconds
+
+The fastest way to explore BEC Widgets. Launch the BEC IPython client with simply `bec` in terminal and the **BECDockArea** opens as the default UI:
+drag widgets, dock/tab/split panes, and explore. Everything is live—widgets auto-connect to BEC/Redis, so you can
+operate immediately and refine later with RPC or Designer if needed.
+
+![dock_area_example](https://github.com/user-attachments/assets/219a2806-19a8-4a07-9734-b7b554850833)
+
+### 2. Qt Designer plugins + BEC Launcher (no glue)
+
+All BEC Widgets ship as **Qt Designer plugins** with our custom Qt Designer launchable by `bec-designer`. Design your UI
+visually in Designer, save a `.ui`, then launch it with
+the **BEC Launcher**—no glue code. Widgets auto‑connect to BEC/Redis on startup, so your UI is operational immediately.
+
+![designer_opti](https://github.com/user-attachments/assets/fed4843c-1cce-438a-b41f-6636fa5e1545)
+
+### 3. Robust RPC from CLI & remote scripting
+
+Operate and automate BEC Widgets directly from the `BECIPythonClient`. Create or attach to GUIs, address any sub-widget
+via a simple hierarchical API with tab-completion, and script event-driven behavior that reacts to BEC (scan lifecycle,
+active devices, topics)—so your UI can be heavily automated.
+
+- Create & control GUIs: launch, load profiles, open/close panels, tweak properties—all from the shell.
+- Hierarchical addressing: navigate widgets and sub-widgets with discoverable paths and tab-completion.
+- Event scripting: subscribe to BEC events (e.g., scan start/finish, device readiness, topic updates) and trigger
+  actions,switch profiles, open diagnostic views, or start specific scans.
+- Remote & headless: run automation on analysis nodes or from notebooks without a local GUI process.
+- Plays with no-code: Use the Dock Area / BEC Designer to set up the layout and add automation with RPC when needed.
+
+![rpc_opti](https://github.com/user-attachments/assets/666be7fb-9a0d-44c2-8d44-2f9d1dae4497)
+
+### 4. Rapid development (extensible by design)
+
+Build new widgets fast: Inherit from `BECWidget`, list your RPC methods in `USER_ACCESS`, and use `bec_dispatcher` to
+bind endpoints. Then run `bw-generate-cli --target <your-plugin-repo>`. This generates the RPC CLI bindings and a Qt
+Designer plugin that are immediately usable with your BEC setup. Widgets
+come online with live BEC/Redis wiring out of the box.
