 [[:Version control]] is a way to develop software in a scalable way. Even if you are the only person working on a project, it enables you to write code with more confidence, as you know you have every change tracked - no more wondering what you did which broke everything, as you can find out easily. You can also tag points in development for retrieval later on - it's a good idea to do this before working on big structural changes which could cause instability while you work on them. [[:Version control]] is a way to develop software in a scalable way.

-Version control can be also be used in order to share development between groups of people, up to hundreds of developers. It takes care of merging all the changes together, which often worries people new to version control but it generally works well, and if it finds a confusing case (normally where two developers have changed the same line of code) it asks you to confirm what it's doing.+Version control can be also be used in order to share development between groups of people, up to hundreds of developers.

 I've set up the lirec svn repository with a dummy project called 'sandbox' that you can play with and break to your heart's content. This guide is written for the commandline version of svn, and heavily biased towards linux. If you prefer buttons to press, read through this document anyway as the concepts are the same, and then have a look at [[http://tortoisesvn.tigris.org/|Tortoise SVN]] or [[http://subclipse.tigris.org/|SubClipse]] if you use Eclipse or [[http://www.visualsvn.com/|VisualSVN]] if you use VisualStudio. [TODO - update this with a guide for using these systems.] I've set up the lirec svn repository with a dummy project called 'sandbox' that you can play with and break to your heart's content.
