+## Configuring PostgreSQL
+
+You can either run PostgreSQL from the machine that runs Plume, or from another server. We recommend you to use the first setup for development environments, or in production for small instances.
+
+In the first case, just run this command after the PostgreSQL installation, to start it:
+
+```
+service postgresql start
+```
+
+If you want to have two separate machines, run these commands on the database server once you've installed the dependencies mentioned above on both servers:
+
+```bash
+service postgresql start
+su - postgres
+createuser -d -P plume

 ## Running migrations
 
 Migrations are scripts used to update the database. They are run by a tool called Diesel, which can be installed with:
 
 ```bash
-cargo install diesel_cli --no-default-features --features postgres --version '=1.2.0'
+cargo install diesel_cli --no-default-features --features $FEATURES --version '=1.3.0'
 ```
 
-Plume should normally run migrations on your behalf as needed, but if you want to run them manually, use the following command:
+To run the migrations, you can do:
 
 ```bash
+# For a PostgreSQL database
 diesel migration run --database-url postgres://USER:PASSWORD@IP:PORT/DATABASE_NAME
+
+# For a SQlite database
+diesel migration run --database-url ./plume.sqlite3
 ```
 
-This command may be useful if you decided to use a separate database server.
+Migrations should be run before using Plume or the `plm` CLI tool, and after each update.
+When in doubt, run them.
