+## Installing PlantUML graphical visualization
 
-## Creating model files
+Graphical visualization is available in Eclipse using the open source [PlantUML](https://plantuml.com) tooling to render diagrams.
 
-1. Create Kernel Modeling Language (KerML) files in the `kerml/src` directory. The extension for a KerML file is `.kerml`.
+0. Make sure that your Eclipse has PlantUML with SysMLv2 extensions.  You can install it from the update site of [ https://dl.bintray.com/himi-sysml/plantuml-sysmlv2/updates/1.1](https://dl.bintray.com/himi-sysml/plantuml-sysmlv2/updates/1.1) with Help > Install New Software
 
-2. Create Systems Modeling Language (SysML) files in the `sysml/src` directory. The extension for a SysML file is `.sysml`.
+1. PlantUML visualization requires that [GraphViz](https://www.graphviz.org) be installed. Visit [ https://www.graphviz.org/download/](https://www.graphviz.org/download/) 
+and download the appropriate package for your environment.
+
+2. If Eclipse cannot automatically find the path to the GraphViz executable, you can set it by going to `Preferences > PlantUML`. 
+For details, visit [ https://plantuml.com/en/eclipse](https://plantuml.com/en/eclipse).
+
+## Working with model files
 
-3. Alternatively, you can create a separate project for your KerML or SysML files. Create the project as a Java project, with
-the `sysml.library` project on the build path.
+1. Double click on a file with a `.kerml` or `.sysml` extension to view it in a Kernel Modeling Language (KerML) or Systems Modeling Language (SysML).
+
+2. Create new KerML files in the `kerml/src` directory with the extension `.kerml`.
 
-4. You can view the model library files in the `sysml.library` project, but *do not change them*.
+2. Create new SysML files in the `sysml/src` directory with the extension `.sysml`.
+
+3. You can view the model library files in the `sysml.library` project, but *do not change them*.
 
-**Release Note:** In the current implementation, there are cases in which the processing of a file with several name resolution errors can take a very long time, 
-particularly if the `Quantities and Units` library is being used. This will be fixed in a future release.
+4. To show SysML diagrams, in `Window > Show View > Other...` select the PlantUML view. The diagram rendered in the view is relative to the text selected 
+in the active SysML editor view. Tree (BDD-like), interconnection (IBD-like) and state machine views are currently supported.
 
-## Graphical visualization
+**Release Note:** While performance has improved significantly in this release, there are still cases in which the processing of a file with 
+several name resolution errors can take a long time, particularly if the `Quantities and Units` library is being used.
 
-This release includes a prototype graphical visualization capability with diagrams rendered using the open source [PlantUML](https://plantuml.com) tooling.
+## Initializing new model projects
 
-0. Make sure that your Eclipse has PlantUML with SysMLv2 extensions.  You can install it from the update site of https://dl.bintray.com/himi-sysml/plantuml-sysmlv2/updates/ with Help > Install New Software
+You can also create a separate project for your KerML or SysML files.
 
-1. PlantUML visualization requires that [GraphViz](https://www.graphviz.org) be installed. Visit [ https://www.graphviz.org/download/](https://www.graphviz.org/download/) 
-and download the appropriate package for your environment.
+1. Select `File > New > Project...` to open the New Project wizard.
 
-2. If Eclipse cannot automatically find the path to the GraphViz executable, you can set it by going to `Preferences > PlantUML`. 
-For details, visit [ https://plantuml.com/en/eclipse](https://plantuml.com/en/eclipse).
+2. Select `General/Project`.
+
+3. Enter the project name (and location if necessary), then press Next.
+
+4. On the Project References page, check the `sysml.library` project. This step tells Eclipse which other projects should be visible for resolving cross-references.
+
+5. Right-click the new project and select `Configure > Convert` to an Xtext project. This step sets up the indexing infrastructure necessary for resolving references between different files.
+
+6. Create any text files with `.kerml` or `.sysml` extensions to start working with a new file.  
 
-3. To show SysML diagrams, in `Window > Show View > Other...` select the PlantUML view. The diagram rendered in the view is relative to the text selected 
-in the active SysML editor view. Basic block definition (class) and state machine diagrams are currently supported.
+**Note:** Adding the project references to an existing project can be done in the project Properties dialog available from the popup menu on the project in the Project References page.
 
+**Note:** If the Xtext setup (step 5) is missed, opening the KerML or SysML editor shows a dialog asking to convert the project to an Xtext project. 
+Accepting this has the same results as manually selecting the menu item on the project.
