+### `tag`
+
+The `tag` subsection provides configuration to set concurrency limit for tag lookup.
+When user calls into the registry to delete the manifest, which in turn then does a
+lookup for all tags that reference the deleted manifest. To find the tag references,
+the registry will iterate every tag in the repository and read it's link file to check
+if it matches the deleted manifest (i.e. to see if uses the same sha256 digest).
+So, the more tags in repository, the worse the performance will be (as there will
+be more S3 API calls occurring for the tag directory lookups and tag file reads if
+using S3 storage driver).
+
+Therefore, add a single flag `concurrencylimit` to set concurrency limit to optimize tag
+lookup performance under the `tag` section. When a value is not provided or equal to 0,
+`GOMAXPROCS` will be used.
+
+```yaml
