+## Local development
+A [`Makefile`](https://github.com/shaarli/Shaarli/blob/master/Makefile) is available to perform project-related operations:
+- Documentation - generate a local HTML copy of the GitHub wiki
+- [[Static analysis]] - check that the code is compliant to PHP conventions
+- [[Unit tests]] - ensure there are no regressions introduced by new commits
+
+## Automatic builds
+[Travis CI](http://docs.travis-ci.com/) is a Continuous Integration build server, that runs a build:
+- each time a commit is merged to the mainline (`master` branch)
+- each time a Pull Request is submitted or updated
+
+A build is composed of several jobs: one for each supported PHP version (see [[Server requirements]]).
+
+Each build job:
+- updates Composer
+- installs 3rd-party test dependencies with Composer
+- runs [[Unit tests]]
+
+After all jobs have finished, Travis returns the results to GitHub:
+- a status icon represents the result for the `master` branch: [![](https://api.travis-ci.org/shaarli/Shaarli.svg)](https://travis-ci.org/shaarli/Shaarli)
+- Pull Requests are updated with the Travis result
+ - Green: all tests have passed
+ - Red: some tests failed
+ - Orange: tests are pending
