 This implements part of the [SCIM standard](http://www.simplecloud.info)
 for identity management. The parts that are currently supported are:
 
- * User schema version 2.0
-
-## Building
-
-This project uses stack. You can install the sample executable with
-
-```sh
-stack install
-```
-
-## Developing and testing
-
-This library only implements the schemas and endpoints defined by the
-SCIM standard. You will need to implement the actual storage by giving
-an instance for the `Persistence` class.
-
-There's a simple in-memory implementation of this class, which is used
-for tests. You can run the tests with the standard stack interface:
-
-```sh
-stack test
-```
-
-# Contributing
-
-Before submitting a PR, make sure to install [ormolu](https://github.com/tweag/ormolu)
-by doing `stack install ormolu` (we pin the version in our `stack.yaml` file)
-and run `make format`.
+ * User schema version 2.0 (partial)
