 |---|---|
 |checkUncovered| If set to true, the monitor will alert also for prefixes not covered by ROAs in addition of RPKI invalid prefixes. |
-|preCacheROAs| When this parameter is set to true (default), BGPalerter will download Validated ROA Payloads (VRPs) lists locally instead of using online validation. More info [here](https://github.com/massimocandela/rpki-validator).|

 |thresholdMinPeers| Minimum number of peers that need to see the BGP update before to trigger an alert. |
-|vrpProvider| A string indicating the provider of the VRPs list. Possible options are: `ntt` (default), `ripe`, `external`. Use external only if you wish to specify a file with `vrpFile`. More info [here](https://github.com/massimocandela/rpki-validator#options).|

 |maxDataSamples| Maximum number of collected BGP messages for each alert which doesn't reach yet the `thresholdMinPeers`. Default to 1000. As soon as the `thresholdMinPeers` is reached, the collected BGP messages are flushed, independently from the value of `maxDataSamples`.|
 |cacheValidPrefixesSeconds| Amount of seconds ROAs get cached in order to identify RPKI repository malfunctions (e.g. disappearing ROAs). Default to 7 days. |

+# RPKI configuration
+
+The RPKI validation performed by BGPalerter can be configured in `config.yml` in the `rpki` section.
+
+```yaml
+rpki:
+  vrpProvider: ntt
+  preCacheROAs: true,
+  refreshVrpListMinutes: 15
+```
+
+This configuration will be used across the entire process (e.g., by `monitorRPKI`, `monitorHijack`, `monitorROAs`).
+
+Below you can see the parameters available:
+
+|Parameter| Description| 
+|---|---|
+|preCacheROAs| When this parameter is set to true (default), BGPalerter will download Validated ROA Payloads (VRPs) lists locally instead of using online validation. More info [here](https://github.com/massimocandela/rpki-validator).|
+|refreshVrpListMinutes| If `preCacheROAs` is set to true, this parameter allows to specify a refresh time for the VRPs lists (it has to be > 15 minutes) |
+|vrpProvider| A string indicating the provider of the VRPs list. Possible options are: `ntt` (default), `ripe`, `cloudflare`, `external`. Use external only if you wish to specify a file with `vrpFile`. More info [here](https://github.com/massimocandela/rpki-validator#options).|
+|vrpFile| A JSON file with an array of VRPs. See example below.|
+
+
+## Generating a VRP file
+Using external VRP providers for the monitoring is quick and easy, but you are essentially trusting somebody else writing the VRP file correctly.
+
+You can generate your JSON VRP file periodically and BGPalerter will load it automatically.
+
+VRPs file example:
+```json5
+[
+    {
+        "prefix": "123.4.5.0/22",
+        "asn": "1234",
+        "maxLength": 24
+    },
+    {
+        "prefix": "321.4.5.0/22",
+        "asn": "9876",
+        "maxLength": 22
+    }
+]
+```
+
+You can use any of the RPKI validator that support JSON as output format. Below some copy-paste examples.
