-A [Python script](misc/collect.py) is included to merge the JSON files:
-`./collect.py bin/ --download-url
-'https://downloads.openwrt.org/releases/{version}/targets/{target}' >
-overview.json`.
+A [Python script](misc/collect.py) is included to merge the JSON files into a single overview.json:
+```
+./collect.py merge bin/ --download-url 'https://downloads.openwrt.org/releases/{version}/targets/{target}' > overview.json
+```
+
+If you want to scrape the OpenWrt download website and update the config.js automatically:
+```
+./collect.py scrape https://downloads.openwrt.org /var/www/firmware_selector
+```
For the OpenWrt 18.06 and 19.07 releases, you need to patch OpenWrt to output JSON files for collect.py (commit [openwrt/openwrt@881ed09](https://github.com/openwrt/openwrt/commit/881ed09ee6e23f6c224184bb7493253c4624fb9f)).
