 # task-machine
 
-A TUI client for the [todo.txt](https://github.com/todotxt/todo.txt) format, written in Haskell,
-that supports automatically creating new tasks based on template tasks.
+A TUI client for the a format inspired by [todo.txt](https://github.com/todotxt/todo.txt), written in Haskell.
 
-For an introduction to the file format, see the [todo.txt readme](https://github.com/todotxt/todo.txt/blob/master/README.md).
-
-## Template tasks
-
-Template tasks allow for automatically creating new tasks on certain dates.
-
-They work by evaluating a formula for the current day.
-If the formula evaluates to `true`, a new task gets added to the current day using the template text specified.
-If it evaluates to `false`, nothing happens.
-
-When creating a template task, a start date can be specified.
-In that case, the formula will be evaluated for every day from the starting date to the current date.
-
-Once all tasks are added, the starting date will be set to one day after the current date automatically,
-to avoid evaluating any day twice, even if no starting date was specified initially.
-
-Template tasks are inspired by Ben Crowell's [when](https://github.com/bcrowell/when) calendar program.
-
-### Format
-
-This is the format for template tasks.
-The square brackets `[]` indicate an optional part of the syntax.
-The curly braces `{}` are part of the syntax.
-
-`# [start-date] {when-formula} [priority] template-text`
-
-- The `#` signals that this line is a template task, not a normal task.
-
-- *Optional*: All days from `start-date` to the current date are tested when creating new tasks.
-It should be in the `YYYY-MM-DD` format.
-If no `start-date` is specified, it is assumed to be the current date.
-
-- The `when-formula` is evaluated in order to decide whether a new task should be created for a day.
-
-- *Optional*: The `priority` is a regular todo.txt priority, for example `(E)`.
-
-- The `template-text` is pretty much a normal task description.
-The only difference is that it supports date expressions.
-
-#### Examples
-
-`# 2018-09-08 {day_of_week == fri} clean the kitchen @home`
-
-`# {d2018-10-20 - today >= 0} (A) daily every day up to (and including) 2018-10-20 with priority A`
-
-`# {day == 20 && month == 10} Tom's birthday ({year - 1978} years old)`
-(if Tom was born on 1978-10-20)
-
-### Date expression
-
-***TODO***: Document properly once it's actually implemented
-
-- *date* + - *number* → *date*
-- *date* - *date* → *number*
-- *number* + - \* / *number* → *number*
-- *number* == != > < >= <= *number* → *boolean*
-- *boolean* && || == != *boolean* → *boolean*
