 Chachacha changes changelogs. This is a tool you can use to keep your changelog tidy,

-and/or contribute by yourself what matters! Yay!

+## Configuration
+
+Starting from 0.1.3, Chachacha supports a small configuration system directly
+embedded in the file via a hack on Markdown link syntax. This allow for
+a number of features like generating compare history:
+
+```shell
+chachacha init
+
+chachacha config git_provider GH
+chachacha config repo_name aogier/chachacha
+chachacha config tag_template 'v{t}'
+
+chachacha added one feature
+chachacha added another feature
+chachacha release
+chachacha security hole
+chachacha added capability

+
+[//]: # (C3-1-DKAC-GGH-Raogier/chachacha-Tv{t})
+```
+Configuration system keys are:
+
+* `git_provider`: a git repo provider driver (supported: `GH` for github.com)
+* `repo_name`: repo name + namespace your repo is
+* `tag_template`: a tag template which maps release versions with tag names.
+  Variable `t` will be expanded with the version number.
