So, to reiterate, when using Git, you probably want to set up three repositories: -* The root repository. This should be a bare repository (meaning that it does not have a working tree checked out), which the other repositories will push to/pull from. It is a bare repository, since there are problems pushing to a repository that has a working directory. This is called _repository_ in [[ikiwiki-makerepo]]'s manual page. Nominally, this bare repository has a `post-commit` hook that would change directory to the ikiwiki leaf node repository below (the working directory for ikiwiki), do a _git pull_, and refresh ikiwiki to regenerate the wiki with any new content. -* The second repository is a clone of the bare root repository, and has a working tree which is used as ikiwiki's srcdir for compiling the wiki. **Never** push to this repository. When running as a [[cgi]], the changes are committed to this repository, and pushed to the master repository above. This is called _srcdir_ in [[ikiwiki-makerepo]]'s manual page. -* The other (third, fourth, fifth, sixth -- however many pleases you) repositories are also clones of the bare root repository above -- and these have a working directory for you to work on. Use either the `git` transport (if available), or `ssh`. These repositories may be on remote machines, your laptop, whereever you find convenient to hack on your wiki. Any new content should be pushed to the bare master repository when you are ready to publish it, and then the post-commit hook of the bare repository will ensure that the ikiwiki's source directory is updated, and the ikiwiki refreshed with the new content. - -Using three or more of repositories isn't the most obvious set up, but it works the best for typical ikiwiki use.

Now, populate your wiki. You could us `cp` to copy over files, use you favourite editor to create files and `git add` them, or you could import a wiki repository from another VCS using `git-svnimport`, `git-archimport`, or `git-cvsimport`.
