-The goal of the GitHub Pages gem is to help GitHub Pages users bootstrap and maintain a Jekyll build environment that most closely matches the GitHub pages build environment. The GitHub Pages gem relies on explicit requirements shared between both users' computers and the build servers to ensure that the result of a user's local build is consistently also the result of the server's build.
+The goal of the GitHub Pages gem is to help GitHub Pages users bootstrap and maintain a Jekyll build environment that most closely matches the GitHub Pages build environment.

 Additional tools, such as tools that integrate with the GitHub API to make managing GitHub Pages sites easier are not the primary goal, but may be within the project's scope.
