* parameter.md: Add docs for updater_seq
Mention the updater_seq parameter which sets the order of the tree
updaters to run and also specifies which ones to run. This can be
useful when pruning is not required or even a custom plugin is
being built along with xgboost.
The `cd ..;` in the one liner takes you up a directory instead of into the xgboost directory. This will cause that step of the installation to fail. It seems like you are meant to enter the xgboost directory as you did in the instructions for installing xgboost without openmp.
