 # Flavors
 
-A repository of different types of containers based on `d.xr.to/base`
+A repository of different types of containers based on `d.xr.to/base`, A list can be found under [Containers](#Containers)
+
+# Building
+
+Building of images is done by `flavor` a simple perl5 tool which automatically creates a dependency graph of containers and runs the builds in parallel if possible.
+
+```
+flavor [-h] [-r <repo>] [-x <images>] [-o] [-j <jobs>] [-p] [all|images...]
+
+Build Docker images with dependency graphing
+
+Options:
+    -x  Comma separated list of images not to rebuild in chain
+    -o  Only build given images, don't build parents
+    -r  Which repo or prefix to use, default: d.xr.to
+    -p  Push image after building
+    -j  How many builds should run at the same time, default: 4
+    -h  Show this help
+```
+
+## Example
+
+```
+[eater@momo flavors]$ ./flavor all
+INFO: building: nginx, php-fpm, php
+INFO: Starting build for nginx
+INFO: Starting build for php
+INFO: Finished build for php
