# Notes

- Download `mongodb-init-replica-set.js` next to this compose file before first startup:
```bash
  curl -o mongodb-init-replica-set.js https://raw.githubusercontent.com/overleaf/overleaf/main/bin/shared/mongodb-init-replica-set.js
```
- MongoDB runs with a replica set (`--replSet overleaf`), which is required by newer Overleaf versions
- If migrating from an older setup (mongo 5.0, no replica set), initialize the replica set manually on existing data rather than relying on the init script
