I have been developing for my company for approximately three years. We serve up a web portal using Microsoft .NET and MS SQL Server on DotNetNuke.

I am going to leave my job full time at the end of April. I am leaving on good terms, and I really care about this company and the state of the web project.

Because I haven't worked in a team environment in a long time, I have probably lost touch with what 'real' setups look like. When I leave, I predict the company will either find another developer to take over, or at least have developers work on a contractual basis.

Because I have not worked with other developers, I am very concerned with leaving the company (and the developer they hire) with a jumbled mess. I'd like to believe I am a good developer and everything makes sense, but I have no way to tell.

My question, is how do I set up the development environment, so the company and the next developer will have little trouble getting started? What would you as a developer like in place before working on a project you've never worked on?

Here's some relevant information:

• There is a development server onsite and a production server offsite in a data center .
• There is a server where backups and source code (Sourcegear Vault) are stored.
• There is no formal documentation but there are comments in the code.
• The company budget is tight so free suggestions will help the best.
• I will be around after the end of April on a consulting basis so I can ask simple questions but I will not be available full time to train someone
