<br />

You want to leverage conventional-changelog to create a `CHANGELOG.md` but none of the available
presets support your commit types or tools, e.g., Bitbucket, JIRA, Trello. This preset supports
configuration via a `.changelogrc.js` file.

<br />

**This package is best used alongside the other `ghostwriter` tools. Each tool can be configured
using the same `.changelogrc.js` file:**

- [commitlint-config-ghostwriter](../commitlint-config-ghostwriter)
- [cz-ghostwriter](../cz-ghostwriter)

<br />

     conventional-changelog-cli -p ghostwriter
     ```

   - Lerna

     ```json
     {

       "command": {
         "version": {
           "changelogPreset": "ghostwriter",
           "conventionalCommits": true
         }
       }

       ...
     }
     ```

   - Semantic Release

     ```js
     module.exports = {
       ...

       plugins: [
         [
           '@semantic-release/commit-analyzer',
           {
             preset: 'ghostwriter',
           },
         ],
         [
           '@semantic-release/release-notes-generator',
           {
             preset: 'ghostwriter',
           },
         ],
       ],

If the scope of a commit is `*` it will be omitted from the changelog.
