+## Contributing
+
+This package uses git-flow as development model, in short that means that:
+
+1. New features should be added to "develop" branch.
+2. "master" branch is reserved for stable releases.
+3. Patches for bugs related with previous releases should always be done in
+    "hotfixes" branch.
+4. All merge commits to master from "hotfixes" should be done
+    using the "--no-ff" flag and from "develop" should avoid merging commits.
+
+Until we have a defined road-map we are going to leave out "release
+"branches" and "feature branches". For more information about this development
+model please refer to [this site.][6]
+
+Thanks you, and happy coding.
