Here are some informative videos on bolting using glue-in bolts (see disclaimer). As usual, please seek professional advice if you decide to bolt a route. Adhere to the local bolting ethics. Especially in South East Asia, be aware that tropical maritime limestone crags have proven extremely corrosive (e.g. Krabi, the thaitanium project). Please read this nice article on climbing anchors and corrosion. Your work and your investment has to last; be considerate to future climbers. Use the appropriate hardware, use quality (some example of bad hardware and what NOT to use can be found here and here).
Climb.co.za provides a good basic overview of bolting.
