 The initial approach of Immich is to become a backup tool, primarily for mobile device usage. Thus, all the assets must be uploaded from the mobile client. The app was architectured to perform that job well.
 
+### What happens to existing files after I choose a new [Storage Template](/docs/features/storage-template.mdx)?
+
+Template changes will only apply to new assets. To retroactively apply the template to previously uploaded assets, run the Storage Migration Job, available on the [Jobs](/docs/features/jobs.md) page.
+
+### Why is object detection not very good?
+
+The model we used for machine learning is a prebuilt model, so the accuracy is not very good. It will hopefully be replaced with a better solution in the future.
+
+### How can I see Immich logs?
+
+Most Immich components are typically deployed using docker. To see logs for deployed docker containers, you can use the [Docker CLI](https://docs.docker.com/engine/reference/commandline/cli/), specifically the `docker logs` command. For examples, see [Docker Help](/docs/guides/docker-help.md)
+
+### How can I run Immich as a non-root user?
+
+1. Set the `PUID`/`PGID` environment variables (in `.env`).
+2. Set the corresponding `user` argument in `docker-compose` for each service.
+3. Add an additional volume to `immich-microservices` that mounts internally to `/usr/src/app/.reverse-geocoding-dump`.
+
+The non-root user/group needs will need read/write access to the volume mounts, including `UPLOAD_LOCATION`.
+
 ### How can I reset the admin password?
 
 The admin password can be reset by running the [reset-admin-password](/docs/features/server-commands.md) command on the immich-server.
+
+### How can I **purge** data from Immich?
+
+Data for Immich comes in two forms:
+
+1. **Metadata** stored in a postgres database, persisted via the `pg_data` volume
+2. **Files** (originals, thumbs, profile, etc.), stored in the `UPLOAD_LOCATION` folder.
+
+To remove the **Metadata** you can stop Immich and delete the volume.
+
+```bash title="Remove Immich (containers and volumes)"
+docker-compose down -v
+```
+
+After removing the the containers and volumes, the **Files** can be cleaned up (if necessary) from the `UPLOAD_LOCATION` by simply deleting an unwanted files or folders.
