+# 2.20.1 (2023-08-07)
+- Introduce versioning to the Splainer project.  The http://splainer.io website has been around for years, and we've just pushed changes as they arrive.   We are now introducing a changelog process, and labeling the current state as "2.20.1" to match the commit https://github.com/o19s/splainer/commit/46cded05908e5d06ebee03f2cccaf836c60f9438#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519.
+- Splainer.io can NOW be deployed into your Solr environment using [Solr Packages](https://solr.apache.org/guide/solr/latest/configuration-guide/package-manager.html).  See the package [README.md](./solr-splainer-package/README.md) for more details.  https://github.com/o19s/splainer/pull/97.

+# Splainer Solr Plugin
+
+This project lets you install Splainer into your Solr as a plugin.
+You can access it via http://localhost:8983/v2/splainer and avoids common CORS and other network problems that you might encounter using the hosted http://splainer.io site.
+
+
+## Building and installation
+
+This plugin requires a manual custom step added after you run the main `grunt dist` process in the Splainer application that builds a complete webapp in the `../dist` directory.  _This should be automated someday ;-( _.
+
+1. Copy the following Javascript and paste it at the bottom of `/dist/scripts/app.js`:
+
+```
+/* Override default config values for talking to Solr
+ * JSONP->GET
+ * */
+angular.module('o19s.splainer-search')
+  .value('defaultSolrConfig', {
+    sanitize:     true,
+    highlight:    true,
+    debug:        true,
+    numberOfRows: 10,
+    escapeQuery:  true,
+    apiMethod:    'GET'
+  });
+```
+
+1. Export the private key:
+
+```
+export SOLR_PACKAGE_SIGNING_PRIVATE_KEY_PATH=~/ssh/solr-private-key.pem
+```
+
+1. Build the package:
+
+```
+mvn package
+```
+
+1. Now for testing, host the solr-splainer-package/repo locally:
+
+First copy the generated jar into the repo directory:
+
+```
+cp target/solr-splainer-package* repo/
+```
+
+```
+python -m http.server
+```
+
+1. In a Run Solr and install the package:
+
+    tar -xf solr-9.3.0.tgz; cd solr-9.3.0/
+    bin/solr start -c -e films -Denable.packages=true
+    bin/solr package add-repo splainer-dev "http://localhost:8000/repo/" 
+    bin/solr package list-available
+    bin/solr package install solr-splainer
+    bin/solr package deploy solr-splainer -y -cluster
+
+1. Navigate to http://localhost:8983/v2/splainer on the browser.
+
+## Changes to make it work in Solr Admin UI
+
+See [diff from main project](https://github.com/o19s/splainer/compare/main...softwaredoug:solr-splainer:main#diff-18e01ac6a833fb1b20ffbad54f0ad8834a765e766f72cccda1e56cb942864d25R30)
+
+* Changes communication with Solr to use GET instead af JSONP, same way the Admin UI communicates with Solr
+
+
+
+
+
+
+
+
+
+
+## Who?
+
+Based on Another Hack by [Doug Turnbull](http://softwaredoug.com) https://github.com/softwaredoug/solr-splainer.   This works if you can't use Solr Packages in your environment.
+
+Created by [OpenSource Connections](http://opensourceconnections.com).
