-          that such additional attribution notices cannot be construed
-          as modifying the License.

-      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,
-      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.

-# 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

-
-or build the image from source:
-
-    docker build -t coredns .
-
-Run with a default config:
-
-    docker run -dt --name=coredns --restart=unless-stopped --ip=172.17.0.2 --ip6=300:49df:7fbd:1987::100 coredns 
-
-Run with a custom config and a custom zone file:
-    
-    docker run -it -v /home/user/CustomConfig:/Corefile -v /home/user/custom.zonefile:/custom.zonefile coredns
