+## Running sheetui
+
+`sheetui --help` will print out help for the command line tags.
+
+Currently this will print out:
+
+```sh
+Usage: sheetui [OPTIONS] <WORKBOOK>
+
+Arguments:
+  <WORKBOOK>
+
+Options:
+  -l, --locale-name <LOCALE_NAME>      [default: en]
+  -t, --timezone-name <TIMEZONE_NAME>  [default: America/New_York]
+      --log-input <LOG_INPUT>
+  -h, --help                           Print help
+  -V, --version                        Print version
+```
+
+## User Interface
+
+The sheetui user interface is loosely inspired by vim. It is a modal interface that is entirely keyboard driven. At nearly any time you can type `Alt-h` to get some context sensitive help.
+
+### Navigation Mode
+
+The interface will start out in navigation mode. You can navigate around the table and between the sheets using the following keybinds:
+
+**Cell Navigation**
+
+* `h`, ⬆️, and `TAB` will move one cell to the left.
+* `l` and, ➡️ will move one cell to the right.
+* `j`, ⬇️, and `Enter` will move one cell down.
+* `k` ⬆️, will move one cell up.
+
+**Sheet Navigation**
+
+* `Ctrl-n` moves to the next sheet
+* `Ctrl-p` moves to the prev sheet
+
+Sheet navigation moving will loop around when you reach the ends.
+
+**Numeric prefixes**
+
+You can prefix each of the keybinds above with a numeric prefix to do them that many times. So typing `123h` will move to the left 123 times. Hitting `Esc` will clear the numeric prefix if you want to cancel it.
+
+**Modifying the Sheet or Cells**
+
+* `e` or `i` will enter CellEdit mode for the current cell.
+* `Ctrl-h` will shorten the width of the column you are on.
+* `Ctrl-l` will lengthen the width of the column you are on.
+
+**Other Keybindings**
+
+* `Ctrl-s` will save the sheet.
+* `q` will exit the application.
+* `:` will enter CommandMode.
+ 
+<aside>Note that for `q` this will not currently prompt you if the sheet is not saved.</aside>
+
+### CellEdit Mode
+
+You enter CellEdit mode by hitting `e` or `i` while in navigation mode. Type what you want into the cell.
+
+Starting with:
+
+* `=` will treat what you type as a formula.
+* `$` will treat it as us currency.
+
+Typing a number will treat the contents as a number. While typing non-numeric text will treat it as text content. <aside>We do not yet support modifying the type of a cell after the fact. We may add this in the future.</aside>
+
+For the most part this should work the same way you expect a spreadsheet to work.
+
+* `Enter` will update the cell contents.
+* `Esc` will cancel editing the cell and leave it unedited.
+
+You can find the functions we support documented here: [ironcalc docs](https://docs.ironcalc.com/functions/lookup-and-reference.html)
+
+### Command Mode
+
+You enter command mode by typing `:` while in navigation mode. You can then type a command and hit `Enter` to execute it or `Esc` to cancel.
+
+The currently supported commands are:
+
+* `write [path]` save the current spreadsheet. If the path is provided it will save it to that path. If omitted it will save to the path you are currently editing. `w` is a shorthand alias for this command.
+* `insert-rows [number]` Inserts a row into the sheet at your current row. If the number is provided then inserts that many rows. If omitted then just inserts one.
+* `insert-cols [number]` Just line `insert-rows` but for columns.
+* `rename-sheet [idx] <name>` rename a sheet. If the idx is provide then renames that sheet. If omitted then it renames the current sheet.
+* `new-sheet [name]` Creates a new sheet. If the name is provided then uses that. If omitted then uses a default sheet name.
+* `select-sheet <name>` Select a sheet by name.
+* `edit <path>` Edit a new spreadsheet at the current path. `e` is a shorthand alias for this command. 
+* `quit` Quits the application. `q` is a shorthand alias for this command.
+
+<aside>Note that in the case of `quit` and `edit` that we do not currently prompt you if the current spreadsheet has not been saved yet. So your changes will be discarded if you have not saved first.</aside>
