Code Archaeology: Becoming Indiana Jones (PHPConf Phillipines)

Code Archaeology: Becoming Indiana Jones (PHPConf Phillipines)

Code archaeology is one of the most important skills you will ever learn as a developer. How many times have you been thrown into legacy projects with no environment setup, no documentation, and little support from coworkers? The ability to hit the ground running on new applications is a sought-after skill for many employers. In this talk, we will take an open-source project that we have never seen before and work through the steps required to get it up and running so we can start contributing today.
