-If you want to use formulas in issues or wikis, then the following example would be useful:
-
-![equation](http://latex.codecogs.com/gif.latex?%5Cnabla%5Ctimes%20H%3D%5Cdot%7BD%7D%2BJ)
-
-For generating the encoded URL, please use the http://www.url-encode-decode.com/ link.
-But beware spaces get transformed into +, you need to substitute them by `%20` yourself.
-Line breaks are possible to, just by inserting `\\`.
-
-If you use python2 you may use the following code snipped
-
-    import urllib
-    s = urllib.quote(r'ds^2 = -c^2 dt^2 + dx^2 + dy^2 + dz^2\\ ds^2 = \eta_{\mu\nu} dx^\mu dx^\nu')
-    print(s)
-
-to get
