 Whenever you add support for new browsers or notice a bug / mismatch, please update the list and check if all tests are still passing. Also, make sure to keep the list of browser aliases up-to-date in `src/constants.js`.
 
 For creating aliases, keep the following guidelines in mind:
- - use snake_case style for names
+ - use only lowercase letters for names
+ - replace special characters such as space and dashes by underscore
  - whenever possible drop the word `browser` from the original browser name
- - replace dashes with underscore
- - avoid capital letters
  - always check for possible duplicates
  - aliases are supposed to also be a shorter version of the original name
 
 Examples:
 `Opera Coast` --> `opera_coast`
 `UC Browser`  --> `uc`
-`SeaMonkey`   --> `sea_monkey`
+`SeaMonkey`   --> `seamonkey`
