+

+2. Code MUST use 4 spaces for indenting, not tabs.
+3. There MUST NOT be a hard limit on line length; the soft limit MUST be 120 characters; lines SHOULD be 80 characters or less.
+4. There MUST be one blank line after the `namespace` declaration, and there MUST be one blank line after the block of `use` declarations.
+5. Opening braces for classes MUST go on the next line, and closing braces MUST go on the next line after the body.
+6. Opening braces for methods MUST go on the next line, and closing braces MUST go on the next line after the body.
+7. Visibility MUST be declared on all properties and methods; `abstract` and `final` MUST be declared before the visibility; `static` MUST be declared after the visibility.
+8. Control structure keywords MUST have one space after them; method and function calls MUST NOT.

+
+### Editor Config
+
+Create the file `.editorconfig` and insert at project root folder. 
+
+```
+[*.php]
+charset = utf-8
+end_of_line = lf
+insert_final_newline = true
+trim_trailing_whitespace = true
+indent_style = space
+indent_size = 4
+```
+
+You can [download the editor config plugin](http://editorconfig.org/#download) to use on your IDE or Text Editor.
+
+### Sublime Text 3
+
+If you want to follow PSR-2 on all your projects without a `.editorconfig` you can edit your Syntax Specific Settings on Sublime to be like this:
+
+```
+{
+    "default_line_ending": "unix",
+    "ensure_newline_at_eof_on_save": true,
+    "rulers":
+    [
+        80,
+        120
+    ],
+    "tab_size": 4,
+    "translate_tabs_to_spaces": true,
+    "trim_trailing_white_space_on_save": true,
+    "word_wrap": "true"
+}
+```
