How to install craftbukkit/spigot

How am I able to put on spigot to my server directory, I can not use /pl or /rl and who can help?

What have you tried?
Usually it is as simple as using the spiggot / craftbukkit menu to compile the version you want (takes a lot of time, be patient), then use the button to copy the server files to the server you wish to use them for, then finally selecting the correct jar file.
