There are still some things to do on your side:

- [ ] - Create a gh-pages branch (just push empty folder or current master)
- [ ] - Check license file
- [ ] - Create a file called release.cmd (see https://github.com/pezipink/SQLProvider/issues/13)
- [ ] - Check build.fsx properties
- [ ] - Check docs/tools/generate.fsx properties
- [ ] - Check if everything works
