we just need to sync it when building doc site, you can make it part of `docs-release-gen`.@manthan-parmar-1998: @zirain
I'll generate a PR for this.@zirain: @manthan-parmar-1998 thanks for taking this.@github-actions: This issue has been automatically marked as stale because it has not had activity in the last 30 days.

+
+                                                  Kubelet generates a private key and uses it to send a
+                                                  PodCertificateRequest to the named signer.  Once the signer approves the
+                                                  request and issues a certificate chain, Kubelet writes the key and
+                                                  certificate chain to the pod filesystem.  The pod does not start until

+
+                                                  Kubelet will begin trying to rotate the certificate at the time indicated
+                                                  by the signer using the PodCertificateRequest.Status.BeginRefreshAt
+                                                  timestamp.
+
+                                                  Kubelet can write a single file, indicated by the credentialBundlePath
+                                                  field, or separate files, indicated by the keyPath and
+                                                  certificateChainPath fields.
+
+                                                  The credential bundle is a single file in PEM format.  The first PEM
+                                                  entry is the private key (in PKCS#8 format), and the remaining PEM
+                                                  entries are the certificate chain issued by the signer (typically,
+                                                  signers will return their certificate chain in leaf-to-root order).
+
+                                                  Prefer using the credential bundle format, since your application code
+                                                  can read it atomically.  If you use keyPath and certificateChainPath,
+                                                  your application must make two separate file reads. If these coincide
+                                                  with a certificate rotation, it is possible that the private key and leaf
+                                                  certificate you read may not correspond to each other.  Your application
+                                                  will need to check for this condition, and re-read until they are
+                                                  consistent.
+
+                                                  The named signer controls chooses the format of the certificate it
+                                                  issues; consult the signer implementation's documentation to learn how to

+
+                                                      The credential bundle is a single file that contains multiple PEM blocks.
+                                                      The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
+                                                      key.
+

+
+                                                  The credential bundle is a single file in PEM format.  The first PEM
+                                                  entry is the private key (in PKCS#8 format), and the remaining PEM
+                                                  entries are the certificate chain issued by the signer (typically,

+
+                                                  Prefer using the credential bundle format, since your application code

+                                                  your application must make two separate file reads. If these coincide

+
+                                                  The credential bundle is a single file in PEM format.  The first PEM
+                                                  entry is the private key (in PKCS#8 format), and the remaining PEM
+                                                  entries are the certificate chain issued by the signer (typically,

+
+                                                  Prefer using the credential bundle format, since your application code
+                                                  can read it atomically.  If you use keyPath and certificateChainPath,
+                                                  your application must make two separate file reads. If these coincide

+                                                  certificate you read may not correspond to each other.  Your application

+                                                      The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
