 Make sure that PostgreSQL is installed and running and that a database with user is set up. A
 good guide how to do this can be found [here](https://djangogirls.gitbooks.io/django-girls-tutorial-extensions/content/optional_postgresql_installation/) (NOTE: stop before the 'Update settings' part).
 
-#### MongoDB
-The metacore part of the project runs on a [MongoDB database](https://docs.mongodb.com/manual/installation/). Make sure to install a MongoDB as well. Eg. on MacOS:
-
-```shell
-$ brew update
-$ brew install mongodb
-```
-
-After installing, create the database:
-```shell
-$ mongo
-> use <database>
-switched to db <database>
-```
-
-To create a user for the database:
-```shell
-> db.createUser({
-user: "<name>",
-pwd: "<cleartext password>",
-roles: [{ role: "readWrite", db: "<database>" }]
-})
-```
-
-The following MongoDB configuration is set by default, you may overwrite it in your local settings:
-```python
-MONGO_DATABASE = {
-    'database': 'scipost',
-    'host': 'localhost',
-    'user': '',
-    'password': '',
-    'port': '27017',
-}
-```

-## Metacore (still in development)
-The Metacore app for citables, sourced - for now only - from Crossref, is available at /metacore.
-In order to get it running on the server (right now implemented on staging), the following things need to be running:
-
-First of all the Mongo daemon (staging server):
-```bash
-/home/scipoststg/webapps/mongo/mongodb-linux-x86_64-amazon-3.6.3/bin/mongod --auth --dbpath /home/scipoststg/webapps/mongo/data --port 21145 --logpath /home/scipoststg/webapps/scipost/logs/mongod.log --fork

-
-### Indexing
-The search methods use the mongo text index for authors/title. They are defined through
-the mongo shell. Execute the following in the mongo shell:
-```bash
-use scipost
-db.citable.createIndex({authors: "text", title: "text", journal: "text"})
