-Description: Make versioning of data.frame easy and efficient using git
-    repositories.
+Description: The git2rdata package is an R package for writing and reading
+  dataframes as plain text files.
+  A metadata file stores important information.
+  1) Storing metadata allows to maintain the classes of variables.
+  By default, git2rdata optimizes the data for file storage.
+  The optimization is most effective on data containing factors.
+  The optimization makes the data less human readable.
+  The user can turn this off when they prefer a human readable format over
+  smaller files.
+  Details on the implementation are available in
+  vignette("plain_text", package = "git2rdata").
+  2) Storing metadata also allows smaller row based diffs between two
+  consecutive commits.
+  This is a useful feature when storing data as plain text files under version
+  control.
+  Details on this part of the implementation are available in
+  vignette("version_control", package = "git2rdata").
+  Although we envisioned git2rdata with a git workflow in mind, you can use it
+  in combination with other version control systems like subversion or
+  mercurial.
+  3) git2rdata is a useful tool in a reproducible and traceable workflow.
+  vignette("workflow", package = "git2rdata") gives a toy example.
+  4) vignette("efficiency", package = "git2rdata") provides some insight into
+  the efficiency of file storage, git repository size and speed for writing and
+  reading.
