Blender plugin to import the proprietary model format A3D used by the game Tanki Online from Alternativa Games, it is not compatible with older the formats used by the flash based Alternativa3D engine (see this plugin by Davide Jones instead).
Check the wiki for file format documentation.
Firstly download the repository by clicking the "Code" button and then "Download ZIP".
In blender, go to Edit > Preferences and click the "add-ons" button. From there click the arrow on the top right and click "Install from disk".
Select the zip folder you downloaded and you should be good to go.
