 # Fulcio
 
-_A New Kind of Root CA For Code Signing_
+_A Free-to-Use CA For Code Signing_
 
-fulcio is a free Root-CA for code signing certs - issuing certificates based on an OIDC email address.
+Fulcio is a free-to-use certificate authority for issuing code signing certificates
+for an OpenID Connect (OIDC) identity, such as email address.
 
-fulcio only signs short-lived certificates that are valid for under 20 minutes.
+Fulcio only issues short-lived certificates that are valid for 10 minutes.
 
-## Status
+## Public Instance
 
-Fulcio is a *work in progress*!
+Fulcio is in General Availability, offering a 99.5 Availability SLO,
+and follows [semver rules](https://semver.org/) for API stability.
 
-We're currently working hard on cutting a 1.0 release and productionizing the public instance.
-We don't have a date yet, but follow along on the [GitHub project](https://github.com/orgs/sigstore/projects/5).
+For uptime data on the Fulcio public instance, see [https://status.sigstore.dev](https://status.sigstore.dev).
 
-The fulcio root certificate running on our public instance (https://fulcio.sigstore.dev) can be obtained and verified against Sigstore's root (at the [sigstore/root-signing](https://github.com/sigstore/root-signing) repository). To do this, install and use [go-tuf](https://github.com/theupdateframework/go-tuf)'s CLI tools:
+Fulcio's certificate chain can be obtained from the `TrustBundle` API, for example for the public instance
+([https://fulcio.sigstore.dev](https://fulcio.sigstore.dev/api/v2/trustBundle)). To verify the public instance,
+you must verify the chain using Sigstore's [TUF](https://theupdateframework.io/) root from the
+[sigstore/root-signing](https://github.com/sigstore/root-signing) repository).
+
+To do this, install and use [go-tuf](https://github.com/theupdateframework/go-tuf)'s CLI tools:
 ```
-$ go get github.com/theupdateframework/go-tuf/cmd/tuf
-$ go get github.com/theupdateframework/go-tuf/cmd/tuf-client
+$ go install github.com/theupdateframework/go-tuf/cmd/tuf-client@06ed59941769f55b7d54158a0be85a16a7475fa7
 ```
 
-Then, obtain trusted root keys for Sigstore. This can be done from a checkout of the Sigstore's root signing repository at a trusted commit (e.g. after the livestreamed root signing ceremony).

 ## API
 
-The API is defined [here](./pkg/api/client.go).
-
-## Transparency
+The API is defined [here](./fulcio.proto). The API can be accessed
+over [HTTP](https://www.sigstore.dev/swagger/?urls.primaryName=Fulcio) or gRPC.
 
-Fulcio will publish issued certificates to a unique Certificate Transparency log (CT-log).
-That log will be hosted by the sigstore project.
+## Certificate Transparency
 
-We encourage auditors to monitor this log, and aim to help people access the data.
+Fulcio will publish issued certificates to a Certificate Transparency log (CT log).
+The log is hosted at `https://ctfe.sigstore.dev/test`. Each year, the log will be updated
+to a new log ID, for example `https://ctfe.sigstore.dev/2022`.
 
-A simple example would be a service that emails users (on a different address) when certficates have been issued on their behalf.
-This can then be used to detect bad behavior or possible compromise.
+The log provides an API documented in [RFC 6962](https://datatracker.ietf.org/doc/rfc6962/).
 
+We encourage auditors to monitor this log for both integrity and specific identities.
+For example, auditors can monitor for when a certificate is issued for certain eamil addresses,
+which will detect misconfiguration or potential compromise of the user's identity.
 
 ## Security
 
-Should you discover any security issues, please refer to sigstore's [security
+Please report any vulnerabilities following sigstore's [security
