## Building Nim projects on Travis CI

Building your code on Travis CI is useful to check regressions against the master and devel branches of Nim.
Same for your code documentation.

Detailed guide, which the following example originates from: +
http://blaxpirit.com/blog/22/advanced-uses-of-travis-ci-with-nim.html[Advanced uses of Travis CI with Nim]

If you don't want to rebuild the Nim compiler you can instead install the .deb packages listed on https://github.com/nim-lang/Nim/wiki/CircleCI[CircleCI] using https://docs.travis-ci.com/user/installing-dependencies[this config]
