+# Pascals Triangle
+
+Compute Pascal's triangle up to a given number of rows.
+
+In Pascal's Triangle each number is computed by adding the numbers to
+the right and left of the current position in the previous row.
+
+```text
+    1
+   1 1
+  1 2 1
+ 1 3 3 1
+1 4 6 4 1
+# ... etc
+```
+
+## Elm Installation
+
+Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
+installation and learning resources.
+
+## Writing the Code
+
+The first time you start an exercise, you'll need to ensure you have the
+appropriate dependencies installed.
+
+```bash
+$ npm install
+```
+
+Execute the tests with:
+
+```bash
+$ npm test
+```
+
+Automatically run tests again when you save changes:
+
+```bash
+$ npm run watch
+```
+
+As you work your way through the test suite, be sure to remove the `skip <|`
+calls from each test until you get them all passing!
+
+## Source
+

+
+## Submitting Incomplete Solutions
+It's possible to submit an incomplete solution so you can see how others have completed the exercise.
