 repository under the [sig-security-tooling/cve-feed/hack](https://github.com/kubernetes/sig-security/tree/main/sig-security-tooling/cve-feed/hack)
 folder is responsible for generating and updating the feed.
 
+#### Local development
+
+To run the feed scripts locally you need Python 3 and pip3. Install dependencies from the `hack` directory:
+
+```bash
+cd sig-security-tooling/cve-feed/hack
+pip3 install -r requirements.txt
+```
+
+If your system restricts global package installs (e.g. externally managed environment), use a virtual environment:
+
+```bash
+cd sig-security-tooling/cve-feed
+python3 -m venv .venv
+source .venv/bin/activate   # On Windows: .venv\Scripts\activate
+pip3 install -r hack/requirements.txt
+```
+
+Then run the Python script from the `hack` directory: `python3 fetch-official-cve-feed.py`.
+
 This bash script, named `fetch-cve-feed.sh`:
 - sets up the Python 3 environment;
 - generates the CVE feed file with `fetch-official-cve-feed.py`;
