+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Trust DID Web - A DID Method
+
+The spec repository for did:tdw -- Trust DID Web DID method.
+
+Read the spec: [https://bcgov.github.io/trustdidweb/](https://bcgov.github.io/trustdidweb/)
+
+Implementations available:
+
+- Typescript: [https://github.com/bcgov/trustdidweb-ts](https://github.com/bcgov/trustdidweb-ts)
+- Python: To be added
+
+## Abstract
+
+The `did:tdw` (Trust DID Web) method is an enhancement to the
+`did:web` protocol, providing a complementary web-based DID method that addresses limitations
+of `did:web`. It's features include the following.
+
+- Ongoing publishing of all DID Document (DIDDoc) versions for a DID instead of,
+  or alongside a `did:web` DID/DIDDoc.
+- Uses the same DID-to-HTTPS transformation as `did:web`.
+- Provides resolvers the full history of the DID using a verifiable chain of
+  updates to the DIDDoc from genesis to deactivation.
+- A self-certifying identifier (SCID) for the DID that is globally
+  unique and derived from the initial DIDDoc that enables DID portability, such
+  as moving the DIDs web location (and so the DID string itself) while retaining
+  the DID's history.
+- DIDDoc updates include a proof signed by the DID Controller(s) *authorized* to
+  update the DID.
+- An optional mechanism for publishing "pre-rotation" keys to prevent loss of
+  control of the DID in cases where an active private key is compromised.
+- DID URL path handling that defaults (but can be overridden) to automatically
+  resolving `<did>/path/to/file` by using a comparable DID-to-HTTPS translation
+  as for the DIDDoc.
+- A DID URL path `<did>/whois` that defaults to automatically returning (if
+  published by the DID controller) a Verifiable Presentation containing
+  Verifiable Credentials with the DID as the `credentialSubject`,
+  signed by the DID.
+
+Combined, the additional features enable greater trust and security without
+compromising the simplicity of `did:web`. The incorporation of the DID Core
+compatible "/whois" path, drawing inspiration from the traditional WHOIS
+protocol, offers an easy to use, decentralized, trust registry.
+This `did:tdw` aims to establish a more trusted and secure web environment by
+providing robust verification processes and enabling transparency and
+authenticity in the management of decentralized digital identities.
+
+## Contributing to the Specification
+
+Pull requests (PRs) to this repository may be accepted. Each commit of a PR must
+have a DCO (Developer Certificate of Origin -
+[https://github.com/apps/dco](https://github.com/apps/dco)) sign-off. This can
+be done from the command line by adding the `-s` (lower case) option on the `git
+commit` command (e.g., `git commit -s -m "Comment about the commit"`).
+
+Rendering and reviewing the spec locally for testing requires `npm` and `node`
+installed. Follow these steps:
+
+- Fork and locally clone the repository.
+- Install `node` and `npm`.
+- Run `npm install` from the root of your local repository.
+- Edit the spec documents (in the `/spec` folder).
+- Run `npm run render`'
+  - Use `npm run edit` to interactively edit, render and review the spec.
+- Review the resulting `index.html` file in a browser.
+
+The specification is currently in
+[Spec-Up](https://github.com/decentralized-identity/spec-up) format. See the
+[Spec-Up Documentation](https://identity.foundation/spec-up/) for a list of
+Spec-Up features and functionality.
