+Getting Help
+============
+
+    | Help! I need somebody
+    | Help! not just anybody
+    | Help! you know I need someone
+    | Help!
+
+    -- The Beatles, Help!
+
+This fragment of the song originally appeared in the 1965 film Help! and was written by Lennon and McCartney, just a
+few years after the development of Mark 1, the first commercial computer. Maybe just a random coincidence, or maybe
+Lennon was just trying to write an email to McCartney.
+
+While the song might have been written with another meaning in mind, it is a good way to describe the situation of many
+researchers who are presented with a new toolbox. Indeed, the situation of many researchers is that the projects they
+are working on are becoming more and more complex in terms of methods and data. Thus, we *open up the doors* to new
+possibilites:
+
+    | When I was younger, so much younger than today
+    | I never needed anybody's help in any way
+    | But now these days are gone, I'm not so self assured
+    | Now I find I've changed my mind and opened up the doors
+
+    -- The Beatles, Help!
+
+The setback with modern research is that current methods are often more complex and require more computing, which
+means that we need to learn concepts from computer science, mathematics, statistics, etc. This is a good thing, but it
+also means that we need to learn new tools and new ways of thinking, which can be a bit overwhelming, to the point that
+we start relying more and more on other researchers. In the end, we might feel like we lose our independence:
+
+    | And now my life has changed in oh so many ways
+    | My independence seems to vanish in the haze
+    | But every now and then I feel so insecure
+    | I know that I just need you like I've never done before
+
+    -- The Beatles, Help!
+
+We can continue with the song, but we think you get the point. The point is that we will need help, and we will need
+to ask for it. We will need to ask for help from our colleagues, from our supervisors, from our friends.
+
+We are a small team of researchers and developers, and we are not experts in *everything at once*. Each one of us has
+a specific expertise, and we are trying to use this expertise to create Junifer. When we conceived Junifer, we thought
+of researchers' problems and tried to come up with the best way to help them, by building a tool that is easy to
+understand, learn and use. Most importantly, we made it to help. We are here to help you and your research.
+
+If you have any questions, problems and / or suggestions, please do not hesitate to contact us. We will be happy to help you
+and we will be happy to hear from you.
+
+Seems nice, no? But we have one condition: **help us help you**.
+
+Communication is the key for you to help us and in turn help you solve your problems. We cannot know what you are
+trying to do, unless you tell us. **The more detailed explanation you give us, the faster we can help you**.
+We have opened several communication channels so that you can contact us in the way that is most convenient for you.
+
+Some people prefer to **write, in detail, with code and figures**. If you are one of those, use the
+`junifer Discussions`_. site on GitHub. This is a place where you can ask questions, and where you can discuss topics
+such as potential new features, or potential new methods.
+
+Some people do **not have a clear idea of what they want**, but they know that they need help. This is not a
+problem, but it is a bit more involved. Since it will require more frequent interactions to try to understand
+what you are trying to do, we have the `junifer matrix channel`_ in which you can chat with us and other junifer users.
+
+Finally, some people **prefer to communicate verbally**. If you are one of those, you might want to join our
+*office hours*. Given that our agenda might vary, office hours will be announced on the
+`junifer matrix channel`_ chat. Feel free to join and just *listen in* if you are too shy to write.
+
+In short, these are the 3 communication channels to get help:
+
+#. Discussions on Github (`junifer Discussions`_):
+
+   Pros:
+
+   * You can write your question in detail.
+   * Your question will not get mixed with other conversations.
+   * Likely to be the fastest way to solve the issue in the long-run.
+
+   Cons:
+
+   * You need to write your question in detail.
+
+#. Chat (`junifer matrix channel`_):
+
+   Pros:
+
+   * You can ask questions in real-time.
+   * You can including code and figures in your question.
+
+   Cons:
+
+   * Real-time depends on the availability of the other users.
+   * It might be difficult to follow if several conversation happens at the same time.
+
+#. Video Calls (*office hours*)
+
+   Pros:
+
+   * You can get real-time feedback.
+   * You will get our undivided attention (no overlapping discussions).
+
+   Cons:
+
+   * We can't read or write code, or even propose solutions for you to test.
+   * You will need to wait for the next *office hour*.
