+# Environments
+
+Hatsu supports dotenv, and you can set environment variables via the `.env` file.
+
+It is required unless it has a suffix (optional).
+
+However, it may exist as a built-in preset (in the source code) or an example preset (in [`.env.example`](https://github.com/importantimport/hatsu/blob/main/.env.example))
+
+## DATABASE_URL
+
+- default: `sqlite::memory:`
+- example: `sqlite://hatsu.sqlite3`
+
+Should be a valid `sqlite:` or `postgres:` URL. see [sea-ql.org](https://www.sea-ql.org/SeaORM/docs/install-and-config/connection/#connection-string)
+
+`sqlite::memory:` is used by default to ensure that hatsu does not report errors as a result.
+
+If you're not using a Postgres database, I recommend keeping the `sqlite://hatsu.sqlite3`.
+
+## HATSU_DOMAIN
+
+- default: None
+- example: `hatsu.local`
+
+The domain name you assigned to this Hatsu instance.
+
+## HATSU_LISTEN_HOST
+
+- default: `127.0.0.1`
+- example: `0.0.0.0`
+
+The hostname on which the Hatsu server listens.
+
+## HATSU_LISTEN_PORT
+
+- default: `3939`
+- example: `3939`
+
+The port on which the Hatsu server listens.
+
+## HATSU_PRIMARY_ACCOUNT
+
+- default: None
+- example: None
+
+The primary account for this Hatsu instance, which cannot be removed and is used as a `signed_fetch_actor`.
+
+## HATSU_ACCESS_TOKEN (optional)
+
+- default: None
+- example: None
+
+For accessing Admin API.
+
+If this value is not set, the Hatsu Admin API will not be available.
+
+This can be any string, but I recommend generating a random uuid v4.
+
+```bash
+echo "\nHATSU_ACCESS_TOKEN = \"$(cat /proc/sys/kernel/random/uuid)\"" >> .env
+```
