+## Documentation
+
+**In order to ease up the process of reading and applying docs, please:**
+
+*   Add an intro to what the documentation is about (a couple of paragraphs should suffice) before presenting links, code, etc., for the sake of context - especially to the non-initiated;
+*   Make very clear what each step is and use language that anyone would understand (KISS);
+*   Don't abbreviate or assume something is banal/easy/common knowledge;
+*   Be specific even when it sounds like it's something everyone knows about.
+    Example of something that should be specified in docs: where to implement the stuff you just wrote about;
+
+**For extra readability purposes:**
+
+*   Use markdown, if possible, for different areas/topics among the doc (text vs code, for example), as well as space;
+*   Break apart config/commands from docs.
+*   If you can't explain a "basic concept" in a easy way without making a wall of text in the middle of your doc, feel free to hyperlink to other documentation where those concepts are already explained, be it Wikipedia or another doc online that has high readability and reliability;
