+description: "Automatic Certificate Management using Let's Encrypt/Vault and Tailscale."
+---
+
+
+In Traefik, TLS Certificates can be generated using Certificates Resolvers.
+
+In Traefik, two certificate resolvers exist:
+
+- [`acme`](./acme.md): It allows generating ACME certificates stored in a file (not distributed).
+- [`tailscale`](./tailscale.md): It allows provisioning TLS certificates for internal Tailscale services.
+
+The Certificates resolvers are defined in the static configuration.
+
+!!! note Referencing a certificate resolver
+    Defining a certificate resolver does not imply that routers are going to use it automatically.
+    Each router or entrypoint that is meant to use the resolver must explicitly reference it.
