 swh-search
 ==========
 
 Search service for the Software Heritage archive.
 
 Currently uses ElasticSearch, and provides only origin search (by URL and metadata)
 
 # Dependencies
 
 Python tests for this module include tests that cannot be run without a local
 ElasticSearch instance, so you need the ElasticSearch server executable on your
 machine (no need to have a running ElasticSearch server).
 
 ## Debian-like host
 
-The following instructions is enough:
-```
-sudo apt install elasticsearch
-```
-
+The elasticsearch package is required. As it's not part of debian-stable,
+[another debian repository is required to be
+configured](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html#deb-repo)
 
 ## Non Debian-like host
 
 The tests expect:
 - `/usr/share/elasticsearch/jdk/bin/java` to exist.
 - `org.elasticsearch.bootstrap.Elasticsearch` to be in java's classpath.
