+    cd mobilizon
+    docker build -t mobilizon -f docker/production/Dockerfile .

+## Update the env file
 
-    cp env .env
+    cd docker/production/

-## run docker-compose
+## Run the service
 
-    docker-compose -f docker-compose-simple.yml up
-    # set user for volumes
-    sudo chown 999:999 db public wal public/upload
-    # in another shell
-    docker-compose -f docker-compose-simple.yml exec -u 0 mobilizon bash
-    su - mobilizon
-    # backup secret
-    mv config/prod.secret.exs config/prod.secret.exs.env
-    # run config generation
-    MIX_ENV=prod mix mobilizon.instance gen -f
-    # reply anything (not used after) except for :
-    # - What is the name of your database? [mobilizon_prod]
-    # - What is the user used to connect to your database? [mobilizon] 
-    # - What is the password used to connect to your database? [autogenerated]
-    # get secret env based bak
-    mv config/prod.secret.exs.env config/prod.secret.exs 
-    # run the db init script as root
-    exit
-    psql -U postgres -p 5432 -h postgres -f setup_db.psql
-    # delete db init sript
-    rm setup_db.psql
-    # create an admin with mobilizon user
-    su - mobilizon
-    cd /app
-    MIX_ENV=prod mix mobilizon.users.new pascoual@tedomum.fr --password mobilizon

+Start by initializing and running the database:
+
+    docker-compose up -d db
+
+Instanciate required Postgres extensions:
+
+    docker-compose exec db psql -U <username>
+    # CREATE EXTENSION pg_trgm;
+    # CREATE EXTENSION unaccent;
+
+
+Then run migrations:
+
+    docker-compose run --rm mobilizon eval Mobilizon.Cli.migrate
+
+Finally, run the application:
+
+    docker-compose up -d mobilizon
+
+## Update the service
+
+Pull the latest image, then run the migrations:
+
+    docker-compose pull mobilizon
+    docker-compose run --rm mobilizon eval Mobilizon.Cli.migrate
+
+Finally, update the service:
+
+    docker-compose up -d mobilizon
