+# CrayFits
+
+## Introduction
+
+[FITS][1] as a microservice.
+
+## Requirements
+
+* Tomcat
+* [Composer][2]
+
+## Installation
+
+### Install FITS webservice
+
+* Download the latest `fits.zip` and `fits.war` from
+[https://projects.iq.harvard.edu/fits/downloads](https://projects.iq.harvard.edu/fits/downloads).
+You may need to install a zip library to unzip the file.
+* Copy the `.war` file to your Tomcat webapps directory and test.
+* Edit the Tomcat `conf/catalina.properties` file by adding the
+following two lines to the bottom of the file:
+```properties
+fits.home=/\<path-to-fits>/fits
+shared.loader=/\<path-to-fits>/fits/lib/*.jar
+```
+* Restart Tomcat.
+* Test the webservice with:
+```bash
+curl -k -F datafile="@/path/to/myfile.jpg" http://[tomcat_domain]:[tomcat_port]/fits/examine
+```
+(note: the ‘@’ is required.)
+
+### Install CrayFITS microservice
+
+* Clone this repository somewhere in your web root.
+* `$ cd /path/to/CrayFits` and run `$ composer install`
+* For production, configure your web server appropriately (e.g. add a VirtualHost for CrayFits in Apache)
+
+To run the microservice on the Symfony Console, enter:
+```bash
+php bin/console server:start *:8050
+```
+in the microservice root folder.
+
+The server is stopped with:
+```bash
+php bin/console server:stop
+```
+On a production machine you'd probably want to configure an additional
+port in Apache.
+
+Note: The ___location of the FITS webserver is stored in the `.env` file in the
+root dir of the Symfony app.  This will have to be reconfigured if the FITS
+server is anywhere other than `localhost:8080/fits`
+
+
+#### Optional: Configure Alpaca to accept derivative requests from Islandora.
+
+To use Alpaca as an interface to this microservice, configure
+an [`islandora-connector-derivative`](https://github.com/Islandora/Alpaca#islandora-connector-derivative)
+appropriate to your installation of CrayFits.
