 To ingest traffic, it is recommended to create a shared bind mount with the docker-compose. One convenient way to set this up is as follows:
 1. On the vulnbox, start a rotating packet sniffer (e.g. tcpdump, suricata, ...)
-1. Using rsync, copy complete captures to the machine running tulip (e.g. to /traffic)

+2. Using rsync, copy complete captures to the machine running tulip (e.g. to /traffic)

 The ingestor will use inotify to watch for new pcap's and suricata logs. No need to set a chron job.
 
 
 ## Suricata synchronization
 
+### Run in Docker
+
+Configure `SURICATA_DIR_HOST` in `.env`.
+
+Create some rules (404 for testing):
+```bash
+. .env
+mkdir -p ${SURICATA_DIR_HOST}/{etc,lib/rules,log}
+echo 'alert tcp any any -> any any (msg: "404 Not Found"; http.stat_code; content:"404"; metadata: tag notfound; sid:4; rev: 1;)' >> ${SURICATA_DIR_HOST}/lib/rules/suricata.rules
+```
+
+After that run (default config for `eve.json` logging was good enough):
+
+```bash
+docker compose -f docker-compose-suricata.yml up -d --build
+```
+
 ### Metadata
 Tags are read from the metadata field of a rule. For example, here's a simple rule to detect a path traversal:
 ```
 alert tcp any any -> any any (msg: "Path Traversal-../"; flow:to_server; content: "../"; metadata: tag path_traversal; sid:1; rev: 1;)
 ```
 Once this rule is seen in traffic, the `path_traversal` tag will automatically be added to the filters in Tulip.
 
+> [!NOTE]
+>
+> After editing Suricata rules (renaming or id change) please:
+>
+> Remove old logs: `rm ${SURICATA_DIR_HOST}/log/*` (otherwise old signatures will be repopulated).
+>
+> Restart Docker containers.
+>
+> If database was only restarted (not dropped), try cleaning tags/signatures with `python wipe_tags.py`.
 
 ### eve.json
 Suricata alerts are read directly from the `eve.json` file. Because this file can get quite verbose when all extensions are enabled, it is recommended to strip the config down a fair bit. For example:
