 Then with a web browser go to `http://localhost:8983/` to see the Admin Console (adjust the hostname for your docker host).
 
 To use Solr, you need to create a "core", an index for your data. For example:
 
-    docker exec -it --user=solr $SOLR_CONTAINER bin/solr create_core -c gettingstarted
+```console
+$ docker exec -it --user=solr my_solr bin/solr create_core -c gettingstarted

 In the web UI if you click on "Core Admin" you should now see the "gettingstarted" core.
 
 If you want to load some example data:
 
-    docker exec -it --user=solr $SOLR_CONTAINER bin/post -c gettingstarted example/exampledocs/manufacturers.xml

 In the UI, find the "Core selector" popup menu and select the "gettingstarted" core, then select the "Query"
 menu item. This gives you a default search for "*:*" which returns all docs. Hit the "Execute Query" button,
