+# Automation to create events across channels (google calendar & discord)
+#### by [Rancho-rachit](https://github.com/Rancho-rachit)
+
+---
+
+### Description:
+
+This script creates events across -
+1. [Google Calendar](https://developersindia.in/events-calendar/)  
+2. [Discord](https://discord.com/channels/669880381649977354/)
+
+---
+
+### FIRST TIME SETUP
+
+1. Get Python3 `sudo apt-get install python3 && python3 --version`
+
+2. Install required packages `pip install -r requirements.txt`
+
+3. Add respective tokens in the `.env` file
+
+   3.1 Discord Bot token [`DISCORD_BOT_TOKEN`] (Get it from [Discord Developers portal](https://discord.com/developers/applications/)) (bot must have MANAGE_EVENT & CREATE_EVENT permission)
+
+   3.2 Guild ID [`DISCORD_GUILD_ID`] (developersIndia => `1229786646468362260`)
+
+   3.3 calendar Id [`GOOGLE_calendar_ID`] (developerIndia => `9f1337e4154910eb1bdb3bfac32b88f69546468b1281a6db58f50a909df5049f@group.calendar.google.com`)
+
+4. Connect Google calendar through [Google cloud Console](https://console.cloud.google.com/)
+
+    4.1 Create a Project on Google Cloud Console
+   
+    4.2 Search for calendar API and enable it
+
+    4.3 Create Credentials ->  OAuth Client ID -> Application type as Desktop
+
+    4.4 Download the Json file 
+
+    4.5 Rename that JSON file as `credentials.json` and save it to the project directory.
+
+5. `python3 main.py` 
+
+---
+
+### NOTES-
+
+> - Google authenication is required for the first time.
+> 
+> - A file `token.json` will be downloaded automatically, and no web login will be needed afterwards.
