+## You will need to create an AWS S3 bucket or digital ocean space in order to store your uploaded documents
+
+### AWS S3 -
+- Step 1 : Create a S3 bucket
+  - Login to AWS console
+  - Navigate to S3 under services
+  - Hit "Create Bucket" button on upper right corner
+  - Remove the check from "block all public access" checkbox(we need this in order to provide access to not-logged in users after OTP verification)
+  - Set bucket versioning and tags as per your requirements
+  - Hit "Create bucket" button
+- Step 2 : Create IAM user and provide access to AWS bucket
+  - Search for "IAM" on the search bar in AWS console
+  - On IAM dashboard, click the number of users(count) under IAM resources table
+  - Hit "create user" button on the upper right corner of the page
+  - Enter the user name & click next
+  - Click create policy, search for S3 and provide the Read, Write & list permissions
+  - Click next and click "Create user"
+ - Step 3 : Generate Credentials
+  - Go to IAM/Users in AWS console
+  - Hit the hyperlink for the user created in the previous step
+  - Click the "Security credentials" tab
+  - Scroll down to "Access keys" and hit "Create access key"
+  - In the next step select "Application running outside AWS"
+  - Add a description tag if needed & hit "Create access key"
+  - In the next step you will see "Access key" and "Secret Access key". Copy both the values.
+  - Set the value of "Access key" to "DO_ACCESS_KEY_ID" environment variable
+  - Set the value of "Secret Access key" to "DO_SECRET_ACCESS_KEY" environment variable
+- Step 3 : Copy bucket credentials
+  - Visit "Amazon S3 -> Buckets" in aws console
+  - Click the bucket created in previous steps & visit the properties tab
+  - Under "Bucket overview" you will find the value of AWS region(for ex. ap-south-1). Set that value to env variable "DO_REGION"
+  - You can create the value for "DO_ENDPOINT" env variable by appending the region value to amazonaws.com (for ex. s3.ap-south-1.amazonaws.com)
+  - You can create the value for "DO_BASEURL" by adding the bucketname in front of the endpoint value(for ex. https://bucketname.s3.ap-south-1.amazonaws.com)
