CONTRIBUTING.markdown

+Contributing to The Project
+===========================
+
+The following is a set of guidelines for contributing to this project. These
+are guidelines, not rules, so use your best judgement and feel free to propose
+changes.
+
+## Commit Messages Styleguide
+
+- use present tense, imperative mood
+- reference issues and merge requests
+- you can use [Gitlab Flavored Markdown](https://docs.gitlab.com/ee/user/markdown.html)
+
+If you want some help, here is a commit template that you can add to your git
+configuration. Save it to a `my-commit-template.txt` file and use `git config
+commit.template my-config-template.txt` to use it automatically.
+
+```
+# [type] If applied, this commit will...    ---->|
+
+
+# Why this change
+
+# Links or keys to tickets and others
+# --- COMMIT END ---
+# Type can be 
+#    feature
+#    fix (bug fix)
+#    doc (changes to documentation)
+#    style (formatting, missing semi colons, etc; no code change)
+#    refactor (refactoring production code)
+#    test (adding missing tests, refactoring tests; no production code change)
+# --------------------
+# Remember to
+#    Separate subject from body with a blank line
+#    Limit the subject line to 50 characters
+#    Capitalize the subject line
+#    Do not end the subject line with a period
+#    Use the imperative mood in the subject line
+#    Wrap the body at 72 characters
+#    Use the body to explain what and why vs. how
+#    Can use multiple lines with "-" for bullet points in body
+# --------------------
+```
