Setting up Immich

A from-scratch setup using Immich's own official compose files, the fastest route to a working install.

1
Download the official compose files
Immich publishes a ready-to-go docker-compose.yml and .env with every release. Grab both into a new folder rather than writing one by hand, it already wires up the database and machine-learning containers correctly.
```
mkdir immich && cd immich
curl -o docker-compose.yml https://github.com/immich-app/immich/releases/latest/download/docker-compose.yml
curl -o .env https://github.com/immich-app/immich/releases/latest/download/example.env
```
2
Set the upload location and a database password
Open .env and edit UPLOAD_LOCATION to point at wherever photos should actually live on disk, and change DB_PASSWORD to something other than the placeholder.
3
Start it
First run pulls a handful of images, including the machine-learning one used for face and object recognition, so it can take a few minutes. Once it's up, the web app is reachable at port 2283.
```
docker compose up -d
```
4
Create the admin account
The first visit to the web app prompts for an admin account, this is local to this server only.
5
Install the mobile app and back up
The Immich app (iOS and Android) points at this server's address and can back up a camera roll automatically in the background, the same way Google Photos or iCloud would. Each person gets their own account rather than sharing one.
