-          the Derivative Works; 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.

-# LwM2M Gateway
-
-[The LwM2M Specifications](http://www.openmobilealliance.org/release/LightweightM2M) is a Lightweight Machine to Machine protocol.
-
-With `emqx_lwm2m`, user is able to send LwM2M commands(READ/WRITE/EXECUTE/...) and get LwM2M response in MQTT way. `emqx_lwm2m` transforms data between MQTT and LwM2M protocol.
-
-emqx_lwm2m needs object definitions to parse data from lwm2m devices. Object definitions are declared by organizations in XML format, you could find those XMLs from [LwM2MRegistry](http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html), download and put them into the directory specified by `lwm2m.xml_dir`. If no associated object definition is found, response from device will be discarded and report an error message in log.
-
-## Load emqx_lwm2m
-
-```
-./bin/emqx_ctl plugins load emqx_lwm2m
-```
-
-## Test emqx-lwm2m using *wakaama*
-
-[wakaama](https://github.com/eclipse/wakaama) is an easy-to-use lwm2m client command line tool.
-
-Start *lwm2mclient* using an endpoint name `ep1`:
-```
-./lwm2mclient -n ep1 -h 127.0.0.1 -p 5683 -4
-```
-
-To send an LwM2M DISCOVER command to *lwm2mclient*, publish an MQTT message to topic `lwm2m/<epn>/dn` (where `<epn>` is the endpoint name of the client), with following payload:
-
-```json
-{
-    "reqID": "2",
-    "msgType": "discover",
-    "data": {
-        "path": "/3/0"
-    }
-}
-```
-
-The MQTT message will be translated to an LwM2M DISCOVER command and sent to the *lwm2mclient*. Then the response of *lwm2mclient* will be in turn translated to an MQTT message, with topic `lwm2m/<epn>/up/resp`, with following payload:
-
-```json
-{
-    "reqID": "2",
-    "msgType": "discover",
-    "data": {
-        "code":"2.05",
-        "codeMsg": "content",
-        "content": [
-            "</3/0>;dim=8",
-            "</3/0/0>",

-            "</3/0/4>",
-            "</3/0/16>"
-        ]
-    }

+# emqx_lwm2m
+
+[LwM2M (Lightweight Machine-to-Machine)](https://lwm2m.openmobilealliance.org/)
+is a protocol designed for IoT devices and machine-to-machine communication.
+It is a lightweight protocol that supports devices with limited processing power and memory.
+
+
+The **LwM2M Gateway** in EMQX can accept LwM2M clients and translate theirevents
+and messages into MQTT Publish messages.
+
+In the current implementation, it has the following limitations:
+- Based UDP/DTLS transport.
+- Only supports v1.0.2. The v1.1.x and v1.2.x is not supported yet.
+- Not included LwM2M Bootstrap services.
+
+## Quick Start
+
+In EMQX 5.0, LwM2M gateways can be configured and enabled through the Dashboard.
+
+It can also be enabled via the HTTP API, and emqx.conf e.g, In emqx.conf:
+
+```properties
+gateway.lwm2m {
+  xml_dir = "etc/lwm2m_xml/"
+  auto_observe = true
+  enable_stats = true
+  idle_timeout = "30s"
+  lifetime_max = "86400s"
+  lifetime_min = "1s"
+  mountpoint = "lwm2m/${endpoint_namea}/"

-## Feature limitations
-
-- emqx_lwm2m implements LwM2M gateway to EMQX, not a full-featured and independent LwM2M server.
-- emqx_lwm2m does not include LwM2M bootstrap server.
-- emqx_lwm2m supports UDP binding, no SMS binding yet.
-- Firmware object is not fully supported now since mqtt to coap block-wise transfer is not available.
-- Object Versioning is not supported now.
-
-## DTLS
-

+emqx_lwm2m needs object definitions to parse data from lwm2m devices. Object definitions are declared by organizations in XML format, you could find those XMLs from [LwM2MRegistry](http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html), download and put them into the directory specified by `lwm2m.xml_dir`. If no associated object definition is found, response from device will be discarded and report an error message in log.

-          the Derivative Works; 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.
