+          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

+          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

+          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

+          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

+      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.

+      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,

+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# PopuraDNS
+
+PopuraDNS is a simple DNS server with decentralized domain names support.
+
+PopuraDNS can:
+
+- Secure all your regular DNS queries with [DNS-over-TLS](https://en.wikipedia.org/wiki/DNS_over_TLS)
+- Resolve the [meshname protocol](https://github.com/zhoreeq/meshname) domains
+- Resolve [Alfis blockchain](https://github.com/Revertron/Alfis) domains
+- Resolve [OpenNIC alternative DNS root](https://www.opennic.org/) domains
+- Can work as an authoritative server for your domains
+
+## Usage
+
+Building from source (requires Golang >=1.17):
+
+    git clone https://github.com/popura-network/PopuraDNS
+    cd PopuraDNS
+    ./build.sh
+
+Run PopuraDNS on port 53535 with a default config file:
+
+    ./coredns -p 53535 -conf ./Corefile
+
+See the `contrib` directory for systemd and openrc example files.
+
+For Docker tips, see `docs/DOCKER_TIPS.md`
+
+## Configuration
+
+PopuraDNS is a special build of CoreDNS.
+See `Corefile` for example PopuraDNS configuration file.
+
+To list all available plugins, run `./coredns -plugins`
