**Compatibility note**: rbenv is _incompatible_ with rvm. Things will appear to work until you try to install a gem. The problem is that rvm actually overrides the `gem` command with a shell function! Please remove any references to rvm before using rbenv.

Heres what `rbenv init` actually does:
|

|

1. Sets up your shims path. This is the only requirement for rbenv to functional properly. You can do this by hand by prepending `~/.rbenv/shims` to your `$PATH`.
|
||||
2. Installs autocompletion. This is entirely optional but pretty useful. Sourcing `~/.rbenv/completions/rbenv.bash` will set that up. There is also a `~/.rbenv/completions/rbenv.zsh` for ZSH users.
|
||||
3. Initial rehash. From time to time you'll need to rebuild you're shim files. Doing this on init makes sure everything is up to date. `rbenv rehash` can always be ran manually.
|
||||
4. Install sh dispatcher. This bit is also optional but allows rbenv and plugins to change variables in your current shell. This makes commands like `rbenv shell` possible. This doesn't do anything crazy like override `cd` or hack your shell prompt. But for some reason you may need `rbenv` to be a real script rather than a shell function.
