-**UM-Bridge** (the **U**Q and **M**odel **Bridge**) provides a unified interface for numerical models that is accessible from virtually any programming language or framework. It is primarily intended for coupling advanced models (e.g. simulations of complex physical processes) to advanced statistics or optimization methods for UQ.
+**UM-Bridge** is a universal interface that makes any numerical model accessible from any programming language or higher-level software. UM-Bridge only assumes that a model returns an output vector for a given input, and possibly offers derivatives and configuration options. While its primary focus is linking advanced uncertainty quantification (UQ) tools to complex simulations, UM-Bridge is also suitable for other fields like optimization or machine learning on numerical models.
 
-Many uncertainty quantification (UQ) and optimization methods treat a model as an abstract function and only interact with the model through operations such as *simple model evaluation*, *gradient evaluation* or *Jacobian action*.
+UM-Bridge accelerates development from method research to applications and from prototype to supercomputer, enabling you to:

-
-The key idea of UM-Bridge is to provide the mathematical "interface" as an abstract interface in software as well. By using **HTTP** behind the scenes, a high degree of flexibility is achieved, allowing for:
+* **seamlessly link** numerical models to UQ codes across languages and frameworks,
+* **break down complexity** of advanced applications into manageable components,
+* **share** your models with collaborators,
+* **benchmark** your algorithms on a community-driven library of benchmark problems, and
+* **scale** your applications from laptop to supercomputer with minimal effort.
 
-* **Coupling** of codes written in arbitrary languages and frameworks
-* **Accelerating** development of advanced software stacks
-* **Containarization** of models → easier collaboration and → access to container-based compute resourcs in the cloud (e.g., GCP, AWS)
-* **Portability** across operating systems
-* **Fully reproducible** models and benchmarks.

-To get started the following minimal Python code will give you a first impression:
+Try out this Python example! It passes an input to a simple 1D test model running on a remote server and prints the model's output.
 
 ```
 import umbridge
-url = "http://testmodel.linusseelinger.de"
-model = umbridge.HTTPModel(url, "forward")
-print(model([[100]]))
-```
 
-This passes an input to a simple 1D test model running on a remote server and prints the model's output.
+model = umbridge.HTTPModel("http://testmodel.linusseelinger.de", "forward")
+print(model([[100.0]]))
+```
