+# CHANGELOG
+
+The CHANGELOG directory is used for individual changelog file practice.
+The `kong/CHANGELOG.md` now is deprecated.
+
+
+## How to add a changelog file for your PR?
+
+1/ Copy the `changelog-template.yaml` file and rename with your PR number or a short message as the filename. For example, `11279.yaml`, `introduce-a-new-changelog-system.yaml`. (Prefer using PR number as it's already unique and wouldn't introduce conflict)
+
+2/ Fill out the changelog template.
+
+
+The description of the changelog file field, please follow the `schema.json` for more details.
+
+- message: Message of the changelog
+- type: Changelog type. (`feature`, `bugfix`, `dependency`, `deprecation`, `breaking_change`)
+- scope: Changelog scope. (`Core`, `Plugin`, `PDK`, `Admin API`, `Performance`, `Configuration`, `Clustering`)
+- prs: List of associated GitHub PRs
+- issues: List of associated GitHub issues
+- jiras: List of associated Jira tickets for internal track
+
+Sample 1
+```yaml
+message: Introduce the request id as core feature.
+type: feat
+scope: Core
+prs:
+  - 11308
+```
+
+Sample 2
+```yaml
+message: Fix response body gets repeated when `kong.response.get_raw_body()` is called multiple times in a request lifecycle.
+type: bugfix
+scope: PDK
+prs:
+  - 11424
+jiras:
+  - "FTI-5296"
+```
+
+
+## changelog command
+
+The `changelog` command tool provides `preview`, and `release` commands.
+
+### Prerequisites
+
+You can skip this part if you're at Kong Bazel virtual env.
+
+Install luajit
+
+Install luarocks libraries
+
+```
+luarocks install penlight --local
+luarocks install lyaml --local
+```
+
+### Usage
+
+```shell
+$ ./changelog -h
+
+Usage: changelog <command> [options]
+
+Commands:
+  release <version>                  release a release note based on the files in the CHANGELOG/unreleased directory.
+  preview <version>                  preview a release note based on the files in the CHANGELOG/unreleased directory.
+
+Options:
+  -h, --help                         display help for command
+
+Examples:
+  changelog preview 1.0.0
+  changelog release 1.0.0
+```
+
+**Preview a release note**
+```shell
+./changelog preview 1.0.0
+```
+
