 ## Installation
 
-To install PSLab on Debian based GNU/Linux system, the following dependencies must be installed.
+pslab-python can be installed from PyPI:
 
-### Dependencies
+	$ pip install pslab
 
-* Python 3.6 or higher [Link to Official download page](https://www.python.org/downloads/windows/)
-* Pip &nbsp; **Support package installer**
-* NumPy &nbsp; **For numerical calculations**
-* PySerial &nbsp; **For device connection**
-* iPython-qtconsole &nbsp; **_Optional_**
+**Note**: Linux users must additionally install a udev rules file for pslab-python to be able to communicate with the PSLab device. The file 99-pslab.rules should be copied from the installation directory to /etc/udev/rules.d/.
 
-**Note**: If you are only interested in using PSLab as an acquisition device without a display/GUI, only one repository  [pslab-python](https://github.com/fossasia/pslab-python) needs to be installed. If you like a GUI, install the [pslab-desktop app](https://github.com/fossasia/pslab-desktop) and follow the instructions of the Readme in that repo.

-### How To Install on Linux
 
-As root (or with sudo):
+#### Validate installtion
 
-    # pip install git+https://github.com/fossasia/pslab-python@master
-
-Done!
-
-### How to Install on Windows
-
-**Step 1**: Install the latest Python version on your computer and configure `PATH` variable to have both Python installation directory and the Scripts directory to access `pip` tools. In Windows, Python is installed in `C:` drive by default. We can set `$PATH` by opening the **Environment variables** dialog box by following the steps below:
-
-1. [Right click on My Computer] 
-2. Select "Properties"
-3. Open "System Properties"
-4. Click "Advanced" tab
-5. Click "Environment Variables" button
-6. Look for "**_PATH_**" in "System Variables" section and click on it and press "Edit" button
-7. To the end of "Variable value" text box, append "`C:\Python34\;C:\Python34\Scripts\;`" (without quotes and `34` may differ depending on the python version installed. It could be 35, 37 ...)
-8. Click "OK" twice to save and move out from path windows
-
-**Step 2**: Open up command prompt and execute the following commands to install the required dependencies.
-
-    $ pip install pyserial
-    $ pip install numpy
-
-#### Validate
-
-1. Download the PSLab-Python library from this repository and extract it to a directory.
-2. Browse in to that directory and create a new file named `test-pslab-libs.py`
-3. Paste the following code into that file and save it.
+1. Plug in the PSLab device and check that both the LEDs light up.
+2. Run the following piece of code in a Python interpreter:
 ```
 from PSL import sciencelab
 I = sciencelab.connect()
 capacitance = I.get_capacitance()
 print(capacitance)
 ```
-4. Plug in the PSLab device and check if both the LEDs are turned on.
-5. Now run this file by typing `python test-pslab-libs.py` on a command prompt and observe a numerical value printed on the screen along with PSLab device version and the port it is connected to.

-### How to Setup the Development Environment
-
-To set up the development environment, install the packages mentioned in dependencies. For building GUI's you can use Qt Designer or create a frontend using any other compatible technology. The PSLab desktop app is using Electron for example.
