Better documentation

Add a more comprehensive readme.

Also let's tinker with the GitHub action and see if we can get it to avoid testing GPG signatures on every PR.

+
+# ProjectManager.com SDK for API v4
+
+This software development kit contains all API definitions for the [ProjectManager.com](https://www.projectmanager.com) REST API v4.  
+
+# Why use the SDK?
+
+The ProjectManager API v4 is available as a REST definition in OpenAPI format.  You can read the documentation online at [developer.projectmanager.com](https://developer.projectmanager.com/).
+
+This SDK provides a few capabilities that developers may find more useful than hand-writing REST API code:
+* Documentation is available in your editor via autocomplete and hover docblocks
+* Patch notes are available detailing changes
+* Automated updates whenever new API endpoints are added
+
+# Using this SDK
+
+Here's how to add this SDK to create a project.  
+
+First, you must add a reference in your `pom.xml` file.  Check [the SonaType central page](https://central.sonatype.com/artifact/com.projectmanager/projectmanagersdk/overview) for the latest version number:
+
+```xml
+<dependency>
+    <groupId>com.projectmanager</groupId>
+    <artifactId>projectmanagersdk</artifactId>
+    <version>97.0.2178</version>
+</dependency>
+```
+
+Next, run `mvn install`.
+
+To create an API client for ProjectManager within Java, you must specify:
+* Your API key, and
+* Your environment URL.
+
+For the ProjectManager production environment, the environment URL is `https://api.projectmanager.com`.
+
+To [obtain a ProjectManager.com API key](https://developer.projectmanager.com/reference/api-keys):
+* Log on to ProjectManager.com
+* Click your name in the bottom left hand corner
+* Select Account, then API
+* Follow the instructions on the page to create a new API key
+
+```java
+import com.projectmanager.ProjectManagerClient;
+
+public class JavaExample
+{
+    public static ProjectManagerClient GetProjectManagerClient(String apiKey, String env)
+    {
+        return ProjectManagerClient
+            .withEnvironment(env)
+            .withBearerToken(apiKey)
+            .WithAppName("MyApplicationName");
+    }
+}
+```
+
+        
+
