# Arbiter
Arbiter is a human-in-the-loop deidentification platform. It runs your
documents through the [Philter / Phileas](https://www.philterd.ai) PII
detector and gives reviewers a fast, focused workflow for confirming or
correcting every detection before the document leaves the redactor.
For full documentation — installation, configuration, user and admin
guides, REST API reference, and more — see
.
## Quick start
**1. Create your `.env` file with a secret key.**
Copy the example file and generate a cryptographically random 256-bit key:
```shell
cp .env.example .env
echo "ARBITER_CRYPTO_SECRET=$(openssl rand -base64 32)" > .env
```
`ARBITER_CRYPTO_SECRET` must be a base64-encoded 32-byte value. Arbiter
refuses to start if it is missing, not valid base64, or does not decode to
exactly 32 bytes.
**2. Build the Docker image.**
```shell
docker compose build
```
**3. Start Arbiter.**
```shell
docker compose up
```
Arbiter will be available at . The bootstrap admin
account is `admin@philterd.ai` with the password set in
`ARBITER_ADMIN_INITIAL_PASSWORD` in `docker-compose.yaml`. Arbiter refuses
to start if that variable is missing or shorter than 12 characters.
