build

Hi build contributor! If you do any change in scripts/master/ or touching any master's html/ directories, you must restart master.chromium.fyi first and ensure that it still works before restarting other masters.

Recipes

If you're here to make a change to ‘recipes’ (the code located in scripts/slave/recipes*), please take a look at the README for more information pertaining to recipes.
