+# mbed-connector-python-quickstart
+This is a quickstart application for the [mbed-connector-api-python](https://github.com/armmbed/mbed-connector-api-python) package.
+The goal of this application is to get the user up and running, using the mbed-connector-python package and talking to devices through mbed Device Connector in under 5 min, 5 steps or less.
+The quickstart webapp is meant to be paired with the [quickstart embedded app](https://github.com/ARMmbed/mbed-client-quickstart). The quickstart web app will allow the user to visualize quickstart embedded devices and interact with them.
+
+### Pre-requisites
+- A [mbed connector](https://connector.mbed.com) account and have generated an [API token](https://connector.mbed.com/#accesskeys)
+- A endpoint running the [mbed client quickstart example](https://github.com/ARMmbed/mbed-client-quickstart)
+- Install the required packages `pip install -r requirements.txt`
+
+### Use
+1. Put your [API key](https://connector.mbed.com/#accesskeys) into the app.py file, replace the following text
+ ```python
+ token = "Change Me" # replace with your API token
+ ```
+ or set an evironment variable called `ACCESS_KEY` with the value of your API key
+2. Run the `app.py` file
+```python
+python ./app.py
+```
+3. Open a web page to the web.py server. Usually [//localhost:8080](//localhost:8080) will work.
+4. Interact with the web page, blink the LED's, subscribe to the resources, click the button on the board and see the numbers tick up on the web app.
+ {{TODO: insert gif's here}}
+5. Modify : go checkout the API for the [mbed-connector-api-python library](https://docs.mbed.com/docs/mbed-connector-api-python/en/latest/) and make your own applications!
+
+
+## Troubleshooting
+Here are some common problems and their solutions.
+
+##### Cannot establish a secure connection
+This is most likely caused by not having the `requests[security]` package installed. If you are using Ubuntu 14.4 LTS you may need to update pip first `pip install -U pip` and then install the requests security package `pip install -U requests[security]`.
+
+##### WebSocket transport not available
+Dont worry about that warning message, it is not applicable to this demo, but likewise the warning message cannot be disabled.
+
+##### ERROR 500 on trying to run the app.py file
+Make sure you added your [Access Key](https://connector.mbed.com/#accesskeys) to the app. You can do this by either changing the value of the `token` variable in the app.py file or by setting the `ACCESS_KEY` environment variable to your access key.
