-A number of templates and tools to develop Qt GUI's with Python effectively.
+Templates & tools to develop Qt GUIs in Python.
 
-Developing GUIs I often find myself creating forms to pass some input and also
-running some task asynchronously so that the interface is still responsive.
+One use case is accepting user input while running another task asynchronously (so that the UI is still responsive).
 
-This little package tries to address both recurring requirements.
-
-1. `UIFormWidget`, a class to help creating Qt forms
-   programmatically, useable in `QDockWidgets` and `QWidget`
-2. `FormDialog`, a `QDialog` with a form inside with OK and Cancel button
-3. `Worker`, a class that defines a `QRunnable` to
-   handle worker thread setup, signals and wrap up

 ## Installation
 
-You may install via `pip` or `conda`
+Via `pip`/`conda`/`mamba`, i.e. any of the following:
 
-```bash
-python -m pip install eqt
-# or
-conda install eqt -c paskino
-```
+- `python -m pip install eqt`
+- `conda install -c conda-forge eqt`
+- `mamba install -c conda-forge eqt`
 
 ## Examples
 
-In the `example` directory there is an example on how to launch a `QDialog` with a form inside using `eqt`'s [`QWidget`](examples/dialog_example.py) or [`FormDialog`](examples/dialog_example_2.py).
+See the [`examples`](examples) directory, e.g. how to launch a `QDialog` with a form inside using `eqt`'s [`QWidget`](examples/dialog_example.py) or [`FormDialog`](examples/dialog_example_2.py).
