  3. Add fish to the list of available shells : sudo -s then echo /usr/local/bin/fish >> /etc/shells

  4. (optional) Set fish as the default shell

Markdown - Resize pictures in GitHub

I found that the "best" way is to use HTML, as it works both in Readme/.md files and also in comments (within Issues, Gist...)

E.g. when adding/editing a comment (within Issues, Gist...) :

  • Upload the picture by drag-and-drop in the text field
  • replace ![image](https://your-image-url.type) with <img src="https://your-image-url.type" width="100" height="100">
