+# Open The Latest Rails Migration
+
+The [`rails.vim`](https://github.com/tpope/vim-rails) plugin comes with a
+lot of handy helpers for quickly navigating to many parts of a Rails
+project. Among these helpers is the `:Emigration` command that makes it easy
+to tab complete and navigate to Rails migration files. Often times the
+migration you want is the latest migration. There is no need for tab
+complete here, just type:
+
+```
+:Emigration
+```
+
+By default this command opens the latest migration in a new buffer.
+
+See `:h rails-:Emigration` for more details.
