 ### *What’s the point of a change log?*
+
 To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.

 ### *Why should I care?*
-Because software tools are for people. If you don’t care, why are you contributing to open source? Surely, there must be a kernel (ha!) of care somewhere in that lovely little brain of yours.

 ## Usage
-**It's really simple!**
 
-- If your **`git remote`** `origin` refers to your GitHub repo, just go to your project folder and run:
+-  Run this:
 
-      github_changelog_generator

--  Or, run this from anywhere:
       `github_changelog_generator -u github_username -p github_project`

-- If you are running it against a repository on a Github Enterprise install, you must specify *both* `--github-site` and `--github-api` command line options:
+- For Github Enterprise repos, specify *both* `--github-site` and `--github-api` options:

For example, to translate the bugs label to Portuguese, instead of setting `config.bugs_label`, you have to set `config.bug_prefix`, and so on.
