 # DACSspace
 
-A simple Python script to evaluate your ArchivesSpace instance for DACS [single-level minimum](http://www2.archivists.org/standards/DACS/part_I/chapter_1) required elements.
+A Python package to evaluate your ArchivesSpace instance for DACS [single-level required](https://saa-ts-dacs.github.io/dacs/06_part_I/02_chapter_01.html#single-level-required) elements.
 
-DACSspace utilizes the ArchivesSpace API to check resources for DACS compliance and produces a csv containing a list of evaluated resources. If a DACS field is present its content will be written to the csv, if a field is missing the csv will read "FALSE" for that item.
+DACSspace utilizes the ArchivesSpace API and a default JSON schema to validate resources. The output is a CSV containing a list of invalid URIs with the following fields: validation status, error count, and explanation.
+
+DACSspace also allows users to specify a schema to validate against other than the default DACS single-level required schema, see [Usage](https://github.com/RockefellerArchiveCenter/DACSspace#usage) section for more information.

Update README to reflect installing DACSspace as a package
Update the [installation](https://github.com/RockefellerArchiveCenter/DACSspace#installation) section of the README to reflect the changes made in PR #61 as part of issue #60. We can now install daccspace as a package which means we no longer need to install the requirements ourselves. 

Instead of `pip install -r requirements.txt` we can use `pip install dacsspace`

From PR #61:
> Adds a [entrypoint](https://python-packaging.readthedocs.io/en/latest/command-line-scripts.html) script which allows DACSspace to be called via the command line. To try this out, from the root of the repository do:
```
pip install .
dacsspace test.csv
```
