 ## Contributing guidelines
 
+Before contributing, you will have to read the contributing guidelines as we will **not** accept your request
+if you do not respect our community guidelines.
+
 #### Filing an issue
 
+When filing an issue, you will have to fill the skeleton of the ebuild in quotes:
+
+```
+EAPI=7
+
+DESCRIPTION=""
+HOMEPAGE=""
+SRC_URI=""
+ 
+LICENSE=""
+```
+
+After this, you can safely file the issue, and we will take care of it.
+
 #### Pulling Merge Requests
+
+When committing and/or pulling merge requests, you will have to respect our
+Committing & Pulling Merge Requests System (CnPMRS)
+so we can easily identify the changes:
+
+- Provide us the Manifest file;
+- Follow the committing & pulling merge request layout (below).
+
+Each commit will have to be based on this layout:
+
+`[CATEGORY]/[PACKAGE_NAME]: [COMMIT_MESSAGE]`
+
+For example, if the package is called **mail-client/freelook-bin**,
+and you have added this package, the commit or merge request should look like this:
+
+`mail-client/freelook-bin: add freelook-bin-[PACKAGE_VERSION]` # e.g. 1.0.0
+
+For example, if the package is called **mail-client/freelook-bin**,
+and you have fixed an error, the commit or merge request should look like this:
+
+`mail-client/freelook-bin: fix QA - EROOT missing slash`
+
+This system also applies on your metadata.xml and Manifest.
