-## Commit Message Format
-
-Please follow the [Conventional Commits](https://www.conventionalcommits.org/) specification for the commit message format. In summary, each commit message consists of a _header_, a _body_ and a _footer_, separated by a single blank line.
+### PR Title Format
 
 ```
 <type>[optional scope]: <description>
+```
 
-[optional body]
+Example:
 
-[optional footer(s)]
+```
+feat(parser): add ability to parse arrays
 ```
 
-Any line of the commit message cannot be longer than 88 characters! This allows the message to be easier to read on GitHub as well as in various Git tools.

 - _style_: Changes that do not affect the meaning of the code (whitespace, formatting, missing semicolons, etc.)
 - _build_: Changes that affect the build system or external dependencies
 - _ci_: Changes to our CI configuration files and scripts
-
-A scope may be provided to a commit’s type, to provide additional contextual information and is contained within parenthesis, e.g.,
-
-```
-feat(parser): add ability to parse arrays
-```
-
-### Description
-
-Each commit must contain a succinct description of the change:
-
-- use the imperative, present tense: "change" not "changed" nor "changes"
-- don't capitalize the first letter
-- no dot(.) at the end
-
-### Body
-
-Just as in the description, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.
-
-### Footer
-
-The footer should contain any information about _Breaking Changes_, and is also the place to reference GitHub issues that this commit _Closes_.
-
-_Breaking Changes_ should start with the words `BREAKING CHANGE:` with a space or two new lines. The rest of the commit message is then used for this.
-
-### Revert
-
-If the commit reverts a previous commit, it should begin with `revert:`, followed by the description. In the body it should say: `Refs: <hash1> <hash2> ...`, where the hashs are the SHA of the commits being reverted, e.g.
-
-```
-revert: let us never again speak of the noodle incident
-
-Refs: 676104e, a215868
-```
