+Currently, solving CAMPD problems is only possible with an installation of Artelys Knitro 12. A switch to open-source implementations is heavily favored, but currently not immediately planned due to time constraints. Please contact the maintainers if you are interested in contributing.

+## Installation
+### Rust
+Just add the dependency to your `Cargo.toml`
+```toml
+feos-campd = "0.2"
+```
+
+### Python
+If you have a Rust compiler installed, you can builf the package directly from source using:
+```
+pip install git+https://github.com/feos-org/feos-campd
+```
 
 ## Usage
+The following sections demonstrates the usage of the framework in Python. The API in Rust and Python is kept as consistent as possible within the boundaries of the languages. Therefore, the basic steps are identical for a design implemented in Rust, for the API details, check out the [documentation](https://docs.rs/feos-campd).

 ### Molecular representation
 ```python
 # define the molecular representation using a molecule superstructure
