-# Mainflux CoAP Adapter
-
-Mainflux CoAP adapter provides an [CoAP](http://coap.technology/) API for sending messages through the
-platform.
-
-## Configuration
-
-The service is configured using the environment variables presented in the
-following table. Note that any unset variables will be replaced with their
-default values.
-
-| Variable              | Description       | Default               |
-|-----------------------|-------------------|-----------------------|
-| COAP_ADAPTER_NATS_URL | NATS instance URL | nats://localhost:4222 |
-
-## Deployment
-
-The service is distributed as Docker container. The following snippet provides
-a compose file template that can be used to deploy the service container locally:
-
-```yaml
-version: "2"
-services:
-  adapter:
-    image: mainflux/coap-adapter:[version]
-    container_name: [instance name]
-    ports:
-      - [host machine port]:5683
-    environment:
-      COAP_ADAPTER_NATS_URL: [NATS instance URL]
-```
-
-To start the service outside of the container, execute the following shell script:
-
-```bash
-# download the latest version of the service
-go get github.com/mainflux/mainflux
-
-cd $GOPATH/src/github.com/mainflux/mainflux/cmd/coap
-
-# compile the app; make sure to set the proper GOOS value
-CGO_ENABLED=0 GOOS=[platform identifier] go build -ldflags "-s" -a -installsuffix cgo -o app
-
-# set the environment variables and run the service
-COAP_ADAPTER_NATS_URL=[NATS instance URL] app
-```
-
-## Usage
-
-For more information about service capabilities and its usage, please check out
-the [API documentation](swagger.yaml).

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      with the Work to which such Contribution(s) was submitted. If You
+      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

+          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.
+

+# Mainflux UI Dashboad
+
+Mainflux UI, dashboard for [Mainflux](https://github.com/mainflux/mainflux) Industrial IoT Messaging and Device Management Server.
+
+> **N.B.** Mainflux UI service is WIP and not suitable for deployment at this moment. You are welcome to contribute and improve it.
+> ## Development
+>- Follow angular-cli [documentation](https://github.com/angular/angular-cli)
+>- Follow [official angular style guide](https://angular.io/styleguide)
+
+## Requirements
+
+You'll need the following software installed to get started.
+
+- [Node](https://nodejs.org/en/) 6  or higher, we recommend current LTS version, together with NPM 3 or higher.
+- [Angular-cli](https://github.com/angular/angular-cli) Newest version with Webpack integration
+- - Depending on how Node is configured on your machine, you may need to run installation command with `sudo`
+- [Git](http://git-scm.com/downloads): Use the installer for your OS.
+  - Windows users can also try [Git for Windows](http://git-for-windows.github.io/).
+- For local Development with [Mainflux composition](https://github.com/mainflux/mainflux) running locally, [Chrome extension for Cross origin](https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi?utm_source=chrome-app-launcher-info-dialog) is required. Because composition is running on different port then our Angular app, we have cross origin.
+
+## Configuration
+
+Change into the directory.
+
+```bash
+cd dashflux
+```
+
+Install the dependencies. If you're running Mac OS or Linux, you may need to run `sudo npm install` instead, depending on how your machine is configured.
+
+```bash
+npm install
+```
+
+Set appropriate endpoint URLs in **environment.ts** (for local development will probably be 0.0.0.0:<_port_>) or **environment.prod.ts** for production.
+
+To start the server, run:
+
+```bash
+ng serve
+```
+
+This will run and assemble our app.
+ **Now go to `localhost:4200` in your browser to see it in action.**
+
+## Deployment
+
+Dashflux is distributed as Docker container. We use nginx to serve dashflux from docker container, supporting environments using docker multi-stage builds.
+Dashflux docker image is available on [Dockerhub mainflux/dashflux](https://hub.docker.com/r/mainflux/dashflux/)
+
+If you want to build image locally, you can build image using the **development** environment:
+
+```bash
+docker build -f docker/Dockerfile  -t dashflux:dev --build-arg env=dev .
+```
+
+Build image using the **production** environment:
+
+```bash
+docker build -t dashflux:prod -f ./docker/Dockerfile .
+```
+
+**Note:** before running *docker build* command, please make sure appropriate endpoint URLs in *environment.ts* or *environment.prod.ts* are set up.
+
+You can test image running
+
+```bash
+docker run -p 80:80 dashflux:dev
+```
+
+This will run dashflux in docker container.
+
+Now go to `http://localhost` in your browser to see it in action.
