Option A — Web Installer (recommended):

git clone https://github.com/ulsklyc/oikos.git && cd oikos
node tools/installer/install-server.js

Then open http://localhost:8090 in your browser. The wizard configures your .env, starts Docker, and creates your admin account — no manual steps needed. Requires Node.js 18+ on the host.

Option B — pre-built image (no clone required):

curl -O https://raw.githubusercontent.com/ulsklyc/oikos/main/docker-compose.yml
curl -O https://raw.githubusercontent.com/ulsklyc/oikos/main/.env.example
cp .env.example .env     # edit .env — set SESSION_SECRET and DB_ENCRYPTION_KEY
docker compose up -d
docker compose exec oikos node setup.js

Option C — build from source:

git clone https://github.com/ulsklyc/oikos.git && cd oikos
cp .env.example .env     # edit .env — set SESSION_SECRET and DB_ENCRYPTION_KEY
docker compose up -d --build
docker compose exec oikos node setup.js

Then open http://localhost:3000 and log in with the admin credentials you set in the previous step. Add family members from Settings.
