 # Installation
-**Install from PyPI**
+## Install from PyPI
 ```
 pip install facebook-downloader
 ```
+> You will need to have the FireFox browser installed and geckodriver properly set up.
 
-### Note
+## Building from source
-> You will need to have the FireFox browser installed on your pc
+**1.** Clone the repository
->> The program is dependent on selenium, so in order to run it, you will have to download and properly setup geckodriver (setup instructions available below)
-
-# Geckodriver setup
-## Linux
-**1. Go to the geckodriver [releases page](https://github.com/mozilla/geckodriver/releases/). Find the latest version of the driver for your platform and download it**
-
-**2. Extract the downloaded file**
 ```
-tar -xvzf geckodriver*
+git clone https://github.com/bellingcat/facebook-downloader
-```
-**3. Add geckodriver to your system path**
-```
-export PATH=$PATH:/path/to/downloaded/geckodriver
 ```
 
-### Note
+**2.** Navigate to the cloned repository
-> If you encounter issues with the above commands, then you should run them as root
+```
+cd facebook-downloader
+```
+
+### Building the Docker container
+```
+docker build --tty my-facebook-downloader .
+```
+
+### Building the facebook-downloader package
+#### Linux
+Find the `install.sh` script and run it
+```
+./install.sh
+```
+> This assumes the script was already made executable with the `chmod +x uninstall.sh` command.
 
 
-## Windows
-**1. Go to the geckodriver [releases page](https://github.com/mozilla/geckodriver/releases/). Find the geckodriver.exe binary for your platform and download it**
-
-**2. Move the downloaded executable to** *C:\Users\yourusername\AppData\Local\Programs\Python\Python310*
-
-### Note
-> The numbers on the directory 'Python310' will depend on the version of Python you have
-
-## Mac OS
-* [Set up Selenium & GeckoDriver (Mac)](https://medium.com/dropout-analytics/selenium-and-geckodriver-on-mac-b411dbfe61bc)
 
+#### Windows
+**1.** Navigate to the facebook-downloader directory
+Find the `install.ps1` script and run it
+```
+.\install.ps1
+```
+> The installation scripts will download and setup geckodriver, then install **facebook-downloader**.
 
 # Usage
+## Package
 ```
 facebook_downloader <video-url>
