Welcome to the technical documentation of *sec-certs* tool for the data analysis of products certified with Common Criteria or FIPS 140 frameworks. If you're looking for general description of the tool, its use cases and capabilites, we refer you to [sec-certs homepage](https://sec-certs.org/). If you are looking for more advanced knowledge, e.g. how to mine your own data, how to extend the tool, and so forth, this is the right place.
-There are three main parts of this documentation. *User's guide* describes high-level use of our tool. Driven by this knowledge, you can progress to *Notebook examples* that showcase some of the API that we use in the form of Jupyter notebooks. The documentation also contains some of the modules documented with `autodoc`, see *API reference*. Still, some dark corners of our codebase are not documented. To inspect the code directly, see the [sec_certs](https://github.com/crocs-muni/sec-certs/tree/main/src/sec_certs) module. If you want, you can run the notebooks as they are stored in the [project repository](https://github.com/crocs-muni/sec-certs/tree/main/notebooks).

+# Advanced user's guide
+```{important}
+This guide is in the making.
+```
+
+## NVD datasets
+
+Our tool matches certificates to their possible CVEs using datasets downloaded from [National Vulnerability Database (NVD)](https://nvd.nist.gov). If you're fully processing the `CCDataset` or `FIPSDataset` by yourself, you must somehow obtain the NVD datasets.
+
+Our tool can seamlessly download the required NVD datasets when needed. We support two download mechanisms:
+
+1. Fetching datasets with the [NVD API](https://nvd.nist.gov/developers/start-here) (preferred way).
+1. Fetching snapshots from seccerts.org.
+
+The following two keys control the behaviour:
+
+```yaml
+preferred_source_nvd_datasets: "api" # set to "sec-certs" to fetch them from sec-certs.org
+nvd_api_key: null # or the actual key value
+```
+
+If you aim to fetch the sources from NVD, we advise you to get an [NVD API key](https://nvd.nist.gov/developers/request-an-api-key) and set the `nvd_api_key` setting accordingly. The download from NVD will work even without API key, it will just be slow. No API key is needed when `preferred_source_nvd_datasets: "sec-certs"`
+
+
+## Inferring inter-certificate reference context
+
+```{important}
+This is an experimental feature.
+```
+
+We provide a model that can predict the context of inter-certificate references based on the text embedded in the artifacts. The model output is not incorporated into the `CCCertificate` instances, but can be dumped into a `.csv` file from where it can be correlated with a DataFrame of certificate features.
+
+To train and deploy the model, it should be sufficient to change some paths and run the [prediction notebook](https://github.com/crocs-muni/sec-certs/blob/main/notebooks/cc/reference_annotations/prediction.ipynb). The output of this notebook is a `prediction.csv` file that can be loaded into the [references notebook](https://github.com/crocs-muni/sec-certs/blob/main/notebooks/cc/references.ipynb). This notebook documents the full analysis of references conducted on the Common Criteria certificates. Among others, the notebook generates some further `.csv` files that can subsequently be plotted via [plotting notebook](https://github.com/crocs-muni/sec-certs/blob/main/notebooks/cc/paper2_plots.ipynb).
