Here we collect answers to question that come up very often.
If you are trying to download QGIS and nothing seems to happen, please consult the download manager of your browser. It can usually be found as an icon (based on arrow, stop-watch or pie-chart) at the top-right corner of your browser window. Click on the icon to see the download progress or cancel the download. The normal procedure with downloads in the browser is such, that it first asks you where to save the file (with a file browser dialogue) and then you have to wait until the download is finished. Because QGIS install packages can be rather large, depending on the operating system, you have to be patient. The download size can be anywhere between several hundred megabytes to sometimes more than one gigabyte (in case of MS Windows MSI packages). Depending on your download speed and the QGIS server load, downloads can take from several minutes up to several hours.
This is a misconception that we hear from time to time, but it is not true. Donating to QGIS is optional. After downloading QGIS, there is a message appearing, reminding that you can optionally donate to QGIS. However, you can press “Close this message” and continue downloading without any problem. We want QGIS to be accessible to anyone, no matter how your financial situation might be. If you are a first-time QGIS user, we recommend that you download, install and test QGIS first and find out if the software is useful for the tasks you want to solve. Only if you like QGIS and it substantially helps with your business, tasks or processes, you should think about donating towards QGIS or supporting it as a sustaining member.
If you are going to ask a QGIS related question via the mailing lists, please provide enough information to help others easily understand what your problem is. Without a clear and precise question, it is very hard for anybody to answer, or it just takes too much time because the answer will be a question to you etc etc. You may provide information such as:
preferably a descriptive title for your email
which QGIS version you used at that moment (exact)
what are you expecting to get
if applicable, what have you tried and the result you got
if your question is about something broken, you may also provide:
Keep in mind that the more precise your question is, the quicker and more accurate the answer can be.
In case of a broken function, you may give a look at QGIS issue tracker before mailing to the list. More information at bug-reporting.
After a successful developer meeting in Zurich (Switzerland), we decided that the next release should be related to it. Since then, all releases have been named after locations of our developer meetings.
Yes you can… BUT depending on your Operating System, it is more or less difficult.

There is no requirement to mention QGIS for maps produced with it. It is of course really welcome if you would like to add a note saying that the map was produced with QGIS. “Made with QGIS” or “Map created using the Free and Open Source QGIS” are good examples of such a note.
Do not say ©QGIS as QGIS does not hold copyrights on your work.
