 =====
 
 Gems for using PowerShell with vim.
+
+This module is intented for the gigantic intersection of PowerShell and Vim users.
+
+Usage
+-----
+To start using, just import the module
+
+```powershell
+Import-Module vim
+```
+
+Start-VimErrorFile
+------------------
+
+Using the --errorfile option of gvim to quickly jump between files or matches from Select-String.
+
+In the same way as you can jump between compilation errors in vim, you can now jump between files or matches piped into
+Start-VimErrorFile
+
+```powershell
+Get-ChildItem -Recurse -Filter *.cs | Select-String throw | Start-VimErrorFile
+
+ls *.txt | stve
+
+# open a new gvim window
+ls *.ps1 | sls function | stve -newinstance
+```
+The above examples open gvim with all locations where an exception in the error list
+
+By adding the following to _vimrc it is quick and easy to jump between the hits with F2 or F3 
+```
+nnoremap <silent> <F2> :bn<CR>
+nnoremap <silent> <S-F2> :bp<CR>
+nnoremap <silent> <F3> :cn<CR>
+nnoremap <silent> <S-F3> :cp<CR>
+```
