  +## Build the docker image for development
  +
  +To build the development docker image locally, run the following command from the project root
  +(you can change the `:dev-build` tag to another name you prefer):
  +
  +```bash
  +docker build -f tools/docker/dev.Dockerfile -t flogo/flogo-web:dev-build .
  +```
  +
  +The building process will start, it might take several minutes depending on your machine resources. Once the build is finished
  +then you should be able to see the docker image listed when running `docker images`.
  +
  +To start the container, run and navigate to `http://localhost:5033` once the container starts, note that you can change

  +
  +```bash
  +docker run -it -p 5033:3303 flogo/flogo-web:dev-build
