+### Building
+
+1. Install [Maven](http://maven.apache.org/).
+2. Package JAR:
+
+    `mvn clean package`
+
+### Running
+
+1. You will need to add the classes would like to visualize to your classpath.
+2. Provide a package glob pattern to identify the classes you want to visualize.
+3. Name your output.
+
+```bash
+java \
+  -cp .:/path/to/your/classes.jar:./target/javainspect-{VERSION}.jar \
+  eu.svjatoslav.inspector.java.methods.Main \
+  /home/user/work/myproject/src/main/java/ com.myproject.* myproject
+```
+
+Here we want to visualize _com.myproject.*_ classes found in
+*/home/user/work/myproject/src/main/java/*. The resulting *dot* and *svg*
+file will be prefixed with *myproject*.
