 To install Mordecai3, run
 
-```
+```bash
 pip install mordecai3
 ```
 
 The library has two external dependencies that you'll need to set up.
 
 First, run following command to download the spaCy model used to identify place names and to compute the tensors used in the ranking model.
 
-```
+```bash
 python -m spacy download en_core_web_trf
 ```
 
 Second, Mordecai3 requires a local instance of Elasticsearch with a Geonames index. Instructions for setting up the index are available here: https://github.com/openeventdata/es-geonames
 
 Once built, the index can be started like this:
 
-```
+```bash
 docker run -d -p 127.0.0.1:9200:9200 -e "discovery.type=single-node" -v $PWD/geonames_index/:/usr/share/elasticsearch/data elasticsearch:7.10.1
