 Logins, adds Following, Removes Following if not followed back after waiting N days and Collects statistics !, just like most Instagram users do.
 
+```
+# to run script
+python3 InstaBot.py
+```
+
+#### Configuring the bot using config.json
+
+Bot behaviour and user account details can be controlled using json file, key-value pairs are self explainatory. currently password is specified in plain text, this will be improved in further commits.
+
+config.json
+```
+{
+  "username": "username",
+  "password": "password",
+  "headless": "True",
+  "add_following" : "True",
+  "random_add" : "True",
+  "max_follower_add" : 10,
+  "remove_following" : "True",
+  "days_to_wait" : 6
+}
+```
+
+**headless** - this controls whether browser should run in Full GUI or not.
+
+**add_following** - set this to "True" if you want to add followers next time the script runs.
+
+**random_add** - usually following are added linearly as shown in the explore page, if following to add is a large number(controlled using max_follower_add) this marks your account as a bot, so to avoid this set this to "True".
+
+**max_follower_add** - number of following to add from explore page, if random_add is set "True", this number is used as a upper limit to generate a random max_follower_add.
+
+**removed_following** - if set to "True", checks if days_to_wait has elapsed, and removes following of the users cached in cache pickle file.
+
+**days_to_wait** - number of days to wait after added following to remove the users if not followed back.
 
-TODO :
+### Running as anacron job
 
-- [ ] Update logic for scrolling down in explore page
+The whole idea of this project being if just adding and removing following after N days will get you followers. since thats what most users do to get people followng them aka mutual following.
+running this script daily to achieve above mentioned task can be tedious, thats where anacron comes to play.
+
+**modfiying /etc/anacrontab**
+
+```
+<days>   <delay>   <job-id>   python3 /home/<sys_user>/<path_to_InstaBot_directory>
+```
+
+**days** - 1, 7, 30 for daily weekly and monthly requirements
+
+**delay** - minutes of delay before running after system startup
+
+**job-id** - unique job-id, choose one which does not conflict with existing system anacron jobs.
+
+### Adding new behaviours
+
+Adding new behaviours is simple as defining new routines and calling them from "\__main\__" following existing methods to log any info or errors, ex: for removing all followers at once. any contributions and feedback are welcome :^).
+
+## TODO :
+
+- [x] Update logic for scrolling down in explore page
 
 - [ ] Update logic to use one function for scrolling
