+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.

+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          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,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          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
+      for any such Derivative Works as a whole, provided Your use,
+      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
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      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.

+  <br>Well-Known DID Verifier (Typescript) 
+  <br>
+</h1>
+
+---
+
+**Warning: This package still is in very early development. Breaking changes without notice will happen at this point!**
+
+---
+
+A `Sphereon SSI-SDK` plugin to verify relationships between the controller of an origin and a DID conforming to the DIF [spec for well-known DID Configurations](https://identity.foundation/.well-known/resources/did-configuration/) It is written in Typescript and can be compiled to any target JavaScript version.
+
+## Available functions
+
+- registerSignatureValidation
+- removeSignatureValidation
+- verifyDomainLinkage
+- verifyDidConfigurationResource
+
+## Usage
+
+### Adding the plugin to an agent:
+
+```typescript
+import { IWellKnownDidVerifier, WellKnownDidVerifier } from '@sphereon/ssi-sdk-wellknown-did-verifier'
+
+const agent = createAgent<IWellKnownDidVerifier>({
+  plugins: [
+    new WellKnownDidVerifier({
+      signatureVerifications: { verified: () => Promise.resolve({ verified: true }) },
+      onlyVerifyServiceDids: true,
+    }),
+  ],
+})
+```
+
+### Register signature verification callback:
+
+Registers a callback function to be called within the verification process, to verify the signature of the credentials within the DID configuration resource.
+
+```typescript
+agent
+  .registerSignatureVerification({
+    signatureVerificationKey: 'example_key',
+    signatureVerification: () => Promise.resolve({ verified: true }),
+  })
+  .then(() => console.log('success'))
+  .catch(() => console.log('failed'))
+```
+
+### Remove signature verification callback:
+
+Removes a registered callback function.
+
+```typescript
+agent
+  .removeSignatureVerification({ signatureVerificationKey: 'example_key' })
+  .then(() => console.log('success'))
+  .catch(() => console.log('failed'))
+```
+
+### Verify domain linkage:
+
+Verifies the relationship between the controller of an origin and a given DID.
+Option available to only verify the service DID.
+
+```typescript
+agent
+  .verifyDomainLinkage({
+    didUrl: 'did:key:z6MkoTHsgNNrby8JzCNQ1iRLyW5QQ6R8Xuu6AA8igGrMVPUM#foo',
+    signatureVerification: 'verified',
+    onlyVerifyServiceDids: false,
+  })
+  .then((result: IDomainLinkageValidation) => console.log(result.status))
+```
+
+### Verify DID configuration resource:
+
+Verifies a DID configuration resource and domain linkage credentials it holds.
+
+You can either pass in a DID configuration resource or fetch it remotely by setting a secure well-known location (origin).
+Option available to only verify a given DID.
+
+```typescript
+agent
+  .verifyDidConfigurationResource({
+    signatureVerification: () => Promise.resolve({ verified: true }),
+    origin: 'https://example.com',
+    did: 'did:key:z6MkoTHsgNNrby8JzCNQ1iRLyW5QQ6R8Xuu6AA8igGrMVPUM#foo',
+  })
+  .then((result: IResourceValidation) => console.log(result.status))
+```
+
+## Installation
+
+```shell
+yarn add @sphereon/ssi-sdk-wellknown-did-verifier
+```
+
+## Build
+
+```shell
+yarn build
+```
