Sorry for that notice but that is the Debian and Derivates way like Ubuntu :
Download a binary file from here :
under terminal there is a description
>> or, download binary file x64 x86 ...
Nota : download your architecture if you don't know type in terminal uname -r
in download folder double-click and extract there :
then do :
sudo mv Typora-linux-x64 /opt/typora
follow this step :
Create the .desktop file in /.local/share/applications/
nano /home/$USER/.local/share/applications/typora.desktop
Paste the following text :
[Desktop Entry]
Type=Application
Terminal=false
Icon=/path/to/icon/icon.png
Name=Typora
Comment=MarkDown Editor
Exec=/opt/typora/Typora
Categories=IDE;
As for Icon and Exec, use either a full path or a "system" name. You can find a lot of typora png in google save it and move to /opt/typora/
with sudo
For Categories, consult the XDG Standards list.
-> desktop-files
