+`go-ucan` currently support the required parts of the UCAN specification: the main specification, delegation and invocation. It leverages the sibling project [`go-did-it`](https://code.sonr.org/go/did-it) for easy and extensible DID support.
 
 Besides that, `go-ucan` also includes:
-- a simplified [DID](https://www.w3.org/TR/did-core/) and [did-key](https://w3c-ccg.github.io/did-method-key/) implementation
-- a [token container](https://github.com/ucan-wg/go-ucan/tree/v1/pkg/container) with CBOR and CAR format, to package and carry tokens together
 - support for encrypted values in token's metadata

-### Testing
-
-The test suite for this package includes test vectors provided by the
-authors of the [`did:key` method specification](https://w3c-ccg.github.io/did-method-key/).
-Some of these tests provide the public key associated with a `did:key`
-as JWKs and an extra (test-only) dependency has been added to unmarshal
-the JWK into a Go `struct`.  Support for the `secp256k1` encryption
-algorithm is experimental (but stable in my experience) and requires the
-addition of the following build tag to properly run:
-
-```
-// go:build jwx_es256k
-```
-
-WARNING: These tests will not run by default!
-
-To include these tests from the CLI, execute the following command:
-
-```
-go test -v ./did -tags jwx_es256k
-```
-
-It should also be possible to configure your IDE to run these tests.  For
-instance, in Codium, add the following JSON snippet to your local project
-configuration:
-
-```
-"go.testTags": "jwx_es256k",
-```
