+# Meetup
+
+Calculate the date of meetups.
+
+Typically meetups happen on the same day of the week.  In this exercise, you
+will take a description of a meetup date, and return the actual meetup date.
+
+Examples of general descriptions are:
+
+- The first Monday of January 2017
+- The third Tuesday of January 2017
+- The wednesteenth of January 2017
+- The last Thursday of January 2017
+
+The descriptors you are expected to parse are:
+first, second, third, fourth, fifth, last, monteenth, tuesteenth, wednesteenth,
+thursteenth, friteenth, saturteenth, sunteenth
+
+Note that "monteenth", "tuesteenth", etc are all made up words. There was a
+meetup whose members realized that there are exactly 7 numbered days in a month
+that end in '-teenth'. Therefore, one is guaranteed that each day of the week
+(Monday, Tuesday, ...) will have exactly one date that is named with '-teenth'
+in every month.
+
+Given examples of a meetup dates, each containing a month, day, year, and
+descriptor calculate the date of the actual meetup.  For example, if given
+"The first Monday of January 2017", the correct meetup date is 2017/1/2.
+
+## Setup
+
+Go through the setup instructions for Javascript to install the necessary
+dependencies:
+
+[https://exercism.io/tracks/javascript/installation](https://exercism.io/tracks/javascript/installation)
+
+## Requirements
+
+Install assignment dependencies:
+
+```bash
+$ npm install
+```
+
+## Making the test suite pass
+
+Execute the tests with:
+
+```bash
+$ npm test
+```
+
+In the test suites all tests but the first have been skipped.
+
+Once you get a test passing, you can enable the next one by changing `xtest` to
+`test`.
