+# ILMO
+
+[Ilmo](https://github.com/moan0s/ILMO2) is an open source library management tool.
+
+Read [the documentation](https://ilmo2.readthedocs.io/) to learn what you can do with it.
+
+**Warning**: This service is a custom solution for a small library. Feel free to use it but don't expect a solution that works for every use case
+
+## Dependencies
+
+This service requires the following other services:
+
+- a [Postgres](postgres.md) database
+- a [Traefik](traefik.md) reverse-proxy server
+
+
+## Configuration
+
+To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
+
+```yaml

+# ilmo                                                                 #

+#                                                                      #

+
+## Setting up the first user
+
+You need to create a first user (unless you import an existing database).
+You can do this conveniently by running
+
+```bash
+just run-tags ilmo-add-superuser --extra-vars=username=USERNAME --extra-vars=password=PASSWORD --extra-vars=email=EMAIL
+```
+
+## Usage
+
+After installation, you can go to the ILMO URL, as defined in `ilmo_hostname`. Log in with the user credentials from above.
+
+Follow the [ILMO documentation](https://ilmo2.readthedocs.io/en/latest/index.html) to learn how to use ILMO.
+
+## Migrate an existing instance
+
+The following assumes you want to migrate from `serverA` to `serverB` (managed by mash) but you just cave to adjust the copy commands if you are on the same server.
+
+Stop the initial instance on `serverA`
+
+```bash
+serverA$ systemctl stop ilmo
+```
+
+Dump the database (depending on your existing setup you might have to adjust this)
+```
+serverA$ pg_dump ilmo > latest.sql
+```
+
+Copy the files to the new server
+
+```bash
+serverA$ rsync -av -e "ssh" latest.sql root@serverB:/mash/ilmo/
+serverA$ rsync -av -e "ssh" data/* root@serverB:/mash/ilmo/data/
+```
+
+Install (but don't start) the service and database on the server and import the database.
+
+```bash
+yourPC$ just run-tags install-postgres
+yourPC$ just run-tags install-ilmo
+yourPC$ just run-tags import-postgres --extra-vars=server_path_postgres_dump=/mash/ilmo/latest.sql --extra-vars=postgres_default_import_database=mash-ilmo
+```
+
+Start the services on the new server
+
+```bash
+yourPC$ just run-tags start
+```
+
+Done 🥳
+
+### Troubleshooting
+
+If you by accident started the service before importing the database you should
+
+* stop the service
+* use `/mash/postgres/bin/cli` to get a database interface
+* Delete the existing database (THIS WILL DELETE ALL DATA!) `DROP DATABASE ilmo WITH (FORCE);`
+* Continue from "Install (but don't start) the service and database on the server and import the database."
