-Guiding Principles:
+# CHANGELOG
 
-Changelogs are for humans, not machines.
-There should be an entry for every single version.
-The same types of changes should be grouped.
-Versions and sections should be linkable.
-The latest version comes first.
-The release date of each version is displayed.
-Mention whether you follow Semantic Versioning.

-Usage:
+### API BREAKING
 
-Change log entries are to be added to the Unreleased section under the

+### Changelog
+
+To manage and generate our changelog, we currently use [unclog](https://github.com/informalsystems/unclog).
+
+Every PR with types `fix`, `feat`, `deps`, and `refactor` should include a file 
+`.changelog/unreleased/${section}/[${component}/]${pr-number}-${short-description}.md`,
+where:
+
+- `section` is one of 
+  `dependencies`, `improvements`, `features`, `bug-fixes`, `state-breaking`, `api-breaking`, 
+  and _**if multiple apply, create multiple files**_;
+- `pr-number` is the PR number;
+- `short-description` is a short (4 to 6 word), hyphen separated description of the change;
+- `component` is used for changes that affect one of the components defined in the [config](.changelog/config.toml), e.g., `tests`, `globalfee`.
+
+For examples, see the [.changelog](.changelog) folder.
+
+Use `unclog` to add a changelog entry in `.changelog` (check the [requirements](https://github.com/informalsystems/unclog#requirements) first): 
+```bash
+# add a general entry
+unclog add 
+   -i "${pr-number}-${short-description}" 
+   -p "${pr-number}" 
+   -s "${section}" 
+   -m "${description}"
+
+# add a entry to a component 
+unclog add 
+   -i "${pr-number}-${short-description}" 
+   -p "${pr-number}" 
+   -c "${component}"
+   -s "${section}" 
+   -m "${description}"
+```
+where `${description}` is a detailed description of the changelog entry.
+
+For example, 
+```bash
+# add an entry for bumping IBC to v4.4.2
+unclog add -i "2554-bump-ibc" -p 2554 -s "dependencies" -m "Bump [ibc-go](https://github.com/cosmos/ibc-go) to [v4.4.2](https://github.com/cosmos/ibc-go/releases/tag/v4.4.2)" 
+
+# add an entry for changing the global fee module;
+# note that the entry is added to both state-breaking and api-breaking sections
+unclog add -i "2424-params" -p 2424 -c globalfee -s "state-breaking" -m "Add \`bypass-min-fee-msg-types\` and \`maxTotalBypassMinFeeMsgGagUsage\` to globalfee params" 
+unclog add -i "2424-params" -p 2424 -c globalfee -s "api-breaking" -m "Add \`bypass-min-fee-msg-types\` and \`maxTotalBypassMinFeeMsgGagUsage\` to globalfee params" 
+```
+
+**Note:** Changelog entries should answer the question: "what is important about this
+change for users to know?" or "what problem does this solve for users?". It
+should not simply be a reiteration of the title of the associated PR, unless the
+title of the PR _very_ clearly explains the benefit of a change to a user.
