+# todo
+
+These two commands can be used to make simple todo-lists that
+are printed to the screen at terminal startup. They are currently
+only implemented for [alacritty], for other terminals consult
+your terminal documentation or find a work around
+
+## SETUP: 
+- Create a file called `todo.nu` and place the `printer` command,
+  calling it at the end.
+- In your `alacritty.yml`, add this
+  ```yml
+  shell:
+    program: /bin/nu  # path to your `nu` executable
+    args:
+       - -e "nu /path/to/todo.nu"
+  ```
+- Create an empty file called `todo.txt`
+- *Recommended*
+  In your `env.nu`, add an environment variable pointing to the `todo.txt`. Example:
+  ```nu
+  $env.TODO = ($nu.config-path | path dirname | path join 'scripts/todo.txt')
+  ```
+- Source the `todo` command in your `config.nu`. Example
+  ```nu
+  source './scripts/todo.nu'
+  ```
+## USAGE:
+- On terminal startup, the printer command is run by `nu` and the
+  list is printed to the screen. If the list is empty, a message
+  indicating so is printed.
+
+- To add items, 
+  ```nu
+  todo -a "finish writing docs"
+  ```
+
+- To remove an item
+  ```nu 
+  # this prints the list(numbered)
+  todo
+  # the index of the item you want to remove 
+  # (starts at 1 but can be changed to start at 0)
+  todo -r 4
+  ```
+
+- To clear the whole list
+  ```nu
+  todo -c
+  ```
+
+- To manually edit the list
+  ```
+  # this opens an editor with the file opened
+  todo -e
+  ```
