 # Compiling data with the NanoFASE data module
 
-The *NanoFASE data module* is a collection of Python scripts that are used to compile input data for the model. It is recommended to use these scripts over and above manually compiling the NetCDF and constants namelist file required by the model, as the data module scripts take care of deriving a variety of [secondary derived variables](netcdf-namelist-input:secondary-derived-variables), amongst other reasons.
+The *NanoFASE data module* (`nfdata`) is a Python library that is used to compile input data for the model.

-## Getting started
+The library can be [found on GitHub](https://github.com/nerc-ceh/nfdata).
 
-```{note}
-The data module is currently only available as standalone scripts, rather than a Python package. This means that you must manually download the repository and set up a computational environment (install the correct packages) to be able to run the scripts, as detailed below. In the future, we will create a Python package from these scripts to ease this process.
-```
+## Getting started
 
-Clone a copy of the repository from GitHub:
+The easiest way to use the library is to [install it from PyPI](https://pypi.org/project/nfdata/). For example, using pip:
 
 ```bash
-$ git clone [email protected]:NERC-CEH/nanofase-data.git
-$ cd nanofase-data
+$ pip install nfdata
 ```
 
-Use Conda (or Mamba) to create a new environmental and install the required packages:
-
-```bash
-$ conda env create -f environment.yaml
-$ conda activate nanofase-data
+```{note}
+We are currently working on a Conda package for the library - watch this space!
 ```
 
-If you don't want to use Conda/Mamba, then the `environment.yaml` file lists the packages that need to be installed.
-
 ## Basic usage
 
-The main script is `nanofase_data.py`:
+Once installed, the library can be run via the command line using the `nfdata` command:
 
 ```
-(nanofase-data) $ python nanofase_data.py --help
-usage: nanofase_data.py [-h] [--output OUTPUT] {create,edit,constants} file
+$ nfdata --help
+usage: nfdata [-h] [--output OUTPUT] {create,edit,constants} file
