   if that is not related to your PR, please make *another* PR for that.
 * Split big pull requests into multiple small ones. An incremental change
   will be faster to review than a huge PR.
+* Use the first comment as a summary explainer of your PR and you should keep this up-to-date as the PR evolves.

+If your PR could cause a breaking change you must add a BREAKING section to this comment e.g.:

  * **PUT** endpoints return status **No Content (204)**, used to **add/assign** existing Objects (e.g. User) to something (e.g. Org-Team)
  * **PATCH** endpoints return changed object and status **OK (200)**, used to **edit/change** an existing object

 An endpoint which changes/edits an object expects all fields to be optional (except ones to identify the object, which are required).

 ### Endpoints returning lists should
  * support pagination (`page` & `limit` options in query)
  * set `X-Total-Count` header via **SetTotalCountHeader** ([example](https://github.com/go-gitea/gitea/blob/7aae98cc5d4113f1e9918b7ee7dd09f67c189e3e/routers/api/v1/repo/issue.go#L444))
 
+## Large Character Comments
+
+Throughout the codebase there are large-text comments for sections of code, e.g.:
+
+```go
+// __________            .__               
+// \______   \ _______  _|__| ______  _  __

+These were created using the `figlet` tool with the `graffiti` font.
+
+A simple way of creating these is to use the following:
+
+```bash
+figlet -f graffiti Review | sed  -e's+^+// +' - | xclip -sel clip -in
+```
+
+## Backports and Frontports
+
+Occasionally backports of PRs are required.
+
+The backported PR title should be:
+
+```
+Title of backported PR (#ORIGINAL_PR_NUMBER)
+```
+
+The first two lines of the summary of the backporting PR should be:
+
+```
+Backport #ORIGINAL_PR_NUMBER
+
+```
+
+with the rest of the summary matching the original PR. Similarly for frontports
+
+---
+
+The below is a script that may be helpful in creating backports. YMMV.
+
+```bash
+#!/bin/sh
+PR="$1"
+SHA="$2"
+VERSION="$3"
+
+if [ -z "$SHA" ]; then
+    SHA=$(gh api /repos/go-gitea/gitea/pulls/$PR -q '.merge_commit_sha')
