Frequently Asked Questions (FAQs): I thought splitting this section from the main post would be beneficial because it's easier to write it and to look in it in case you need an answer and I have it down there. I hope there are almost no questions because I think my guide is clear enough, though it's normal there will be some questions out here since my explanations aren't perfect. That's why this dedicated section exists. Questions will be marked with a big Q and answers will be marked with a A. Both will be big enough to easily tell them apart. Question list: Questions & Answers: Q: I get a warning message while trying to make a Pull Request on GitHub. What happens? A: You can't make a pull request if you get a warning message from GitHub. Those messages usually provide enough information to tell you what to do. Here are all warnings I've received from GitHub to date and its possible solutions – just remember to change HerculesUser to your GitHub username–: Oops! HerculesWS:master is already up-to-date with HerculesUser:master Try a different branch?You haven't pushed any changes to your remote repository or the changes you've pushed make it identical to the original Hercules repository. You can only make a pull request if your repository is not exactly the same as the original Hercules'. Oops! There's already a pull request for HerculesUser:master Try a different branch or view the pull request?You already have an active pull request on Hercules and you have to wait until it's approved or rejected. If you want to add changes to your pull request, you can push more changes to your repository if you want: they'll automatically be added to your active pull request. Q: How do I update my fork to Hercules' last version? A: This is quite simple but not as easy as updating an official Hercules repository as you can't just pull as you did when updating the original Hercules repository – if you try to pull on your fork you're pulling from your fork's repository, not Hercules' –. Doing this task also depends on your OS: On Windows: (I don't deem necessary to add a how-to picture for this)Right-click your Hercules fork folder and select Fetch... option from the TortoiseGit submenu. A new window will pop up. Select Arbitrary URL option and place original Hercules repository URL there (I mean this one: https://github.com/HerculesWS/Hercules.git). Then click OK (unless you want to change any of the available options, which is unfrequent) for making the fetch update to start. Another window will be opened and your fork will be updated to Hercules last revision. Close it once you're done. On Unix: You just have to run this command (it's actually two commands joint on a single shell statement): git fetch upstream && git merge upstream/master Just remember that if you want these changes to also be on your GitHub repository, you'll have to push them. Otherwise they'll just be available on your local repository, as always. Q: I always get an error message whenever I try to push my changes even though I make sure I put correct access credentials. What happens? A: I've just experienced this error when I tried to push to the wrong repository (i.e. the original Hercules repository, to which I don't have access and you surely don't). Make sure you're trying to push to a repository on which you have permission for this. Ah! Also make sure you have an active Internet connection since you'll be using it! Q: I can't commit anything to my local repository. What happens? A: Chances are you're trying to make a commit without changing any file, and that's not possible for Git. Maybe you actually changed some files but forgot to save them?
