+
+1. **Be aware that it may cost you money.**
+2. Create a Cloudflare account and enable R2 feature. **Credit card info might be required by Cloudflare**, though Cloudflare provides generous free tier and zero egress fee.
+3. Create a bucket.

+
+Cloudflare doesn't allow `HeadBucket` for access keys with "Object Read & Write". So it may be possible that checking connectivity is not ok but actual syncing is ok. New version >= 0.3.29 of the plugin fix this problem by using `ListObjects` instead of `HeadBucket`.

+# AWS S3 Bucket: How to configure user's policy

+## Attention
+
+Please read the doc carefully and adjust the optional fields accordingly. The doc is not fully tested and contributions are welcome.

+## AWS Official Docs

+- <https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations.html>
+
+## Prerequisites
+
+Using the principle of least privilege is crucial for security when allowing a third party system to access your AWS resources.
+
+**Prerequisites**: Ensure you have an AWS account and administrative access to manage IAM policies.
+
+## Step 1: Create a new IAM Policy
+
+1. Log in to your AWS Management Console.
+1. Navigate to the IAM Policies section.
+1. Create a new policy with the following configuration.
+
+**Note**: `my-bucket` is a placeholder. For example, if your bucket's name is `obsidian-data`, the resource line should read `arn:aws:s3:::obsidian-data`.
+
+```JSON
+{
+    "Version": "2012-10-17",
+    "Statement": [
+        {
+            "Sid": "ObsidianBucket",
+            "Effect": "Allow",
+            "Action": [
+                "s3:HeadBucket"
+            ],
+            "Resource": "arn:aws:s3:::my-bucket"
+        },
+        {
+            "Sid": "ObsidianObjects",
+            "Effect": "Allow",
+            "Action": [
+                "s3:HeadObject",
+                "s3:PutObject",
+                "s3:CopyObject",
+                "s3:UploadPart",
+                "s3:UploadPartCopy",
+                "s3:ListMultipartUploads",
+                "s3:AbortMultipartUpload",
+                "s3:CompleteMultipartUpload",
+                "s3:ListObjects",
+                "s3:ListObjectsV2",
+                "s3:ListParts",
+                "s3:GetObject",
+                "s3:GetObjectAttributes",
+                "s3:DeleteObject",
+                "s3:DeleteObjects"
+            ],
+            "Resource": "arn:aws:s3:::my-bucket/*"
+        }
+    ]
+}
+```
+
+> The policy allows the Obsidian plugin to list, add, retrieve, and delete objects in the specified S3 bucket.
+
+## Step 2: Attach the Policy to Obsidian user
+
+1. Create a new user in the IAM console. (Never use your own root user, as it would have full access to your AWS account).
+1. When creating the user, select "Attach policy directly" and select the policy created.
+1. Edit the recent created user and go to "Security Credentials" tab to create your access key.
+1. Create an Access Key. If asked for a "use case", select "other"
+1. Use the credentials in the plugin settings. (NEVER share these credentials)
+
+> PS. The bucket doesn't need to have a policy, only the user.
+
+## Verifying the Policy
+
+After attaching the policy, test it by trying to access the S3 bucket through the Obsidian plugin. Ensure that all intended actions can be performed without errors.
+
+## Troubleshooting
+
+If you encounter permission errors, check the policy for typos in the bucket name or actions. Ensure the policy is attached to the correct user.

+# Sync Ignoring Large Files
+
+Initially, the plugin does not ignore large files.
+
+From the new version in May 2022, it can ignore all files with some sizes. But we need some rules to make the function compatible with existing conditions.
+
+1. If users are using E2E password mode, then the file sizes are compared on the **encrypted sizes**, rather than the original unencripted file sizes. The reasons are: the encrypted ones are in transferations, and the encrypted sizes can be computed from unencrypted sizes but not the reverse.
+
+2. Assuming the file A, is already synced between local device and remote service before.
+
+   - If the local size and remote size are both below the threshold, then the file can be synced normally.
+   - If the local size and remote size are both above the threshold, then the file will be ignored normally.
+   - If the local size is below the threshold, and the remote size is above the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - If the local size is above the threshold, and the remote size is below the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - When it somes to deletions, the same rules apply.
+
+   The main point is that, if the file sizes "cross the line", the plugin does not introduce any further trouble and just reject to work for this file.
