Documentation for adding missing locations

[HectorB-2020]

Expected behaviour

README or similar file must contain steps on how to add missing locations.

1. Should we contribute to this project or directly to libgweather?
2. How often do you sync with libgweather if ever?
3. Is it possible to add a city without code which is defined as mandatory?
4. Can the same code be used several times in the XML file for different cities in the same region?
5. Should it be an airport actively sharing weather details? What happens if the specified code if officially registered in databases but doesn't report its weather?
6. What is general guideline which coordinates should be used on <city> level and which ones of the <location> level? Usually they are close but still different.
7. When users type a name for seeking a place to add, does it look for 'cities' or for 'locations'?
8. When <pref-lang> is used? I found only a few occasions in the XML file.
9. Should we place local names directly in the XML file like xml:lang="" or rather deal with transifex?
10. How critical/desired is to put text in msgctxt=""?
11. Is there a recommendation on how to sort or order this XML file?
12. Should it be one file for all cities/locations or it should be split into regions or countries?

Actual behaviour

README or similar file should contain steps and examples on how to add missing locations.
Currently potential contributors are obliged to review list of previous Issues, previously asked questions and answers and peruse code.

libmateweather is more or less in maintenance only mode since it is on our roadmap to switch to libgweather, see mate-desktop/mate-panel#1075. So, for quick short term changes you can contribute to libmateweather, but for the long-term libgweather is planned.
