+## Deploy
+If you're using [Heroku](https://www.heroku.com), you'll need [CMAKE buildpacks](https://elements.heroku.com/buildpacks/Starkast/heroku-buildpack-cmake) to build this gems. To add it to your app :
+
+```
+$ heroku buildpacks:remove heroku/ruby
+$ heroku buildpacks:add starkast/cmake
+$ heroku buildpacks:add heroku/ruby
+$ heroku buildpacks 
+=== mytool Buildpack URLs
+1. starkast/cmake
+2. heroku/ruby
+$ git push heroku master
+```
+
 ## Todo
 There are quite a few outstanding tasks:
-- [ ] Try to link the robots.dylib library from c-build instead of creating a symbolic link to /usr/local/lib/ to make it compatible with different OS
 - [ ] Some tests :-)
