Documentation
# Casibase
## First-boot
Default admin login: `admin` / `123` — **change immediately** (Account → Edit Password).
## Core concepts
- **Stores** = knowledge bases. Upload PDFs/MDs/DOCX, Casibase chunks + embeds them.
- **Providers** = LLM + embedding endpoints (OpenAI, Anthropic, Azure, local). Configure at Providers tab.
- **Chats** = assistants tied to specific stores; each chat session uses the store's vector index for retrieval.
## Build your first KB
1. **Providers** → Add → pick OpenAI (or others) → paste key.
2. **Stores** → Add → name + description → pick the embedding provider + chat provider.
3. Inside the store, **Files** → Upload → drop your docs.
4. **Chats** tab → New chat → pick the store → start asking questions.
## RBAC
Under the hood, Casibase uses Casdoor for identity + Casbin for authorization. Default config gives the bundled admin user full access. To open up to multiple users:
1. **Casdoor** sidebar entry → Users → Add
2. Each user gets a role; roles map to store permissions.
3. Self-hosting Casdoor as a separate service is supported; the all-in-one bundles it for simplicity.
## Storage
MySQL bundled in the all-in-one image. All state at `/data` (mysql + uploads + index). 20 GB volume.
