+## Scope
 
-## Why nfse-php?
-
-Emitting NFS-e in Brazil involves XML signing with ICP-Brasil certificates, SOAP/REST calls to multiple municipal gateways, and safe credential management — all of which most accounting software gets wrong.
-
-**nfse-php** handles all of it correctly:
-
-- **XML signing** with PFX/PKCS#12 certificates (native PHP first, CLI repack fallback for OpenSSL legacy format)
-- **Credential isolation** — PFX passwords are never stored in your database; they live in [OpenBao](https://openbao.org/) / HashiCorp Vault KV v2
-- **Pluggable secret store** — swap OpenBao for any `SecretStoreInterface` implementation
-- **Tier-1 tests always run** via `donatj/mock-webserver` (no real cert required in CI)
-- **Strict PHP 8.2+ types** throughout
-

 ## Secret Storage with OpenBao
 
-PFX passwords are **never** persisted in application databases. They are stored in OpenBao (or Vault) KV v2 under a path like `nfse/pfx/{cnpj}`.
-
-The CNPJ values below are **fictitious examples**. Configure your own values through your application settings/environment.
+PFX passwords are stored in OpenBao (or Vault) KV v2, for example in `nfse/pfx/{cnpj}`.

-For development/CI without OpenBao, use `NoOpSecretStore` which reads directly from constructor arguments and never touches any server.

-## Roadmap
-
-- [x] DPS issuance via SEFIN Nacional REST API
-- [x] XML signing (PFX, ICP-Brasil)
-- [x] OpenBao / Vault KV v2 secret store
-- [x] Mock webserver for CI-friendly testing
-- [ ] NFS-e query (GET /dps/{id})
-- [ ] NFS-e cancellation
-- [ ] Webhook / event polling
-- [ ] Municipal gateway adapters beyond Niterói
