When you begin your runic journey, you strictly speaking do not need any prior experience in other magickal systems. The runes are a complete system in themselves.
The runes are a way to transform yourself and to interact with the hidden powers of the nine worlds. They can bring you knowledge, power and wisdom.
Before you start down the runic journey prepare yourself for the actual work with the runes. Learn as much as you can about their origin and the mythology. Feel free to buy some books on that matter, however there are numerous excellent articles to be found on the web, just google yourself there. Don't bother with books on 25 runes as the blank rune is an invention from the 1980s or books that use the UTHARK or those that are militant feminists or similar. Ralph Blum eg is dead out. Not only does he cover the blank or wyrd rune, he also reorganised the entire system and relies mostly on his own interpretation on the runes which is far from historical traditions.
Additional to the various online sources Wikipedia offers a good summary on the history of the runes while both the Poetic and the Prose Edda are easily available online.
When you are familiar with both history and mythology, take up study of the runes themselves. A detailed description of the Elder Futhark can be found here. Learning the meaning of the rune alone is not enough however. While you are studying one of the runes I suggest you also use them in meditations to delve deeper into their mysteries. This exercise is also useful for the additional skills you need if you wish to do rune magick, namely concentration, visualisation and breath control.
During meditation, the name of the rune can be used as mantra.
While you are learning the runes you should also learn how to read and write them fluently, again the associated letters to each rune can be found here.
Once you are familiar enough with all the runes that are in the system you picked you can go and create your own rune set as described on this page. This is also an excellent exercise where you make use of everything that you have learned. This set of runes you can then use for divination.
Whatever you do in your runic work, I highly recommend writing everything down in a journal so that you can always refer to it later on.
Essential Tools for Runic Work
Additional tools for rune work are not strictly necessary unless you feel inclined to add sword, dagger, incense and all the other paraphernalia the tradinonalists are so fond of.
