+# Development resources and information for Ecovacs Robot Vacuums
+
+For a description of the Ecovacs API protocols, see
+[the protocol documentation](protocol.md)
+
+
+## Getting started with Sucks
+
+If you'd like to join in on developing, I recommend checking out the code,
+[setting up a virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtualenv/),
+and installing this package in dev mode. You can confirm your environment
+works by running the tests. The commands for that look something like
+like
+
+```
+% python3 -m virtualenv env
+% source env/bin/activate
+% pip install -e .[dev]
+% nosetests
+```
+
+If the test run is successful, it will say something like
+
+```
+Ran 44 tests in 0.734s
+
+OK
+```
+
+Current test are not yet
+comprehensive, as the integrated nature of this makes it difficult.
+But we aim to reduce that problem over time, so please add tests as you go.
+
+
+## MITM XMPP traffic between the Android or iOS App and the Ecovacs server
+
+1. Download [xmpppeek](https://www.beneaththewaves.net/Software/XMPPPeek.html)
+2. Create a self-signed certificate with the following command
+
+`openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes`
+
+3. Edit xmpppeek.py and change port to 5223
+
+4. Look at the  [the protocol documentation](protocol.md) for information on which
+Ecovacs XMPP server is the right one for your Country. For example, a US user will
+be using msg-na.ecouser.net. Find and note the IP address for the server.
+
+5. Make sure the mobile App talks to your machine instead of the server. This can be
+accomplished modifying your router's DNS configuration to have the Ecovacs domain
+name point to your IP.
+
+6. Run xmppeek as follows.
+
+`python ./xmpppeek.py <ECOVACS XMPP SERVER IP> cert.pem key.pem`
+
+
+## Reset robot to factory settings
+
+Ecovacs robots have an undocumented hardware reset button that can be useful
+in case you run into trouble. Under the dustbin lid there is a small round hole
+that hides the button (confirmed on models M80 and M81).
+
+With the robot on, use something thin like a paper clip or needle to press and
+hold the reset button. After about three seconds the robot will beep three times
+to indicate successful reset.
+
+You will have to delete the robot from the mobile app and go through the setup
+process.
