 # facebook_comment_automation
 Your friend just offered to do something silly for commenting in thousands in their post? look no further! You are in the right repo xD 
+
+## overview
+It's a simple selenium automation implementation. It logs in your account and then goes to your friends timeline and finds the latest post and starts commenting.
+
+## Prerequisites
+- You will need have Python3
+- Setup virtualenv and install selenium
+```console
+your_pc$ virtualenv -p /usr/bin/python3 venv
+```
+```console
+your_pc$ source venv/bin/activate
+```
+```console
+(venv)your_pc$ pip install selenium
+```
+- Have firefox installed
+- I used geckodriver for linux. If you run windows, install geckodriver for windows.
+- Rename env_sample.json to env.json and configure it with your username,password and target's username
+
+## Running
+You will need to add PATH for geckodriver
+```console
+(venv)your_pc$ export PATH=$PATH:.
+```
+```console
+(venv)your_pc$ python main.py
+```
+
+## Process Steps of the bot
+- goes to facebook.com
+- logs in to your account
+- goes to targets's timeline
+- selects latest post
+- starts commenting random letters
