-# BUILDING YOUR LIBRARY
-
-See the homepage `https://github.com/swagger-api/swagger-codegen` for full details.
-But briefly, clone the git repository, build the codegen codebase, set up your build
-config file, then run the API build script. You will need git, Java 7 or 8 and Apache
-maven 3.0.3 or better already installed.
-
-Your library files will be built under `WWW::MyProjectName`.
-
-          $ git clone https://github.com/swagger-api/swagger-codegen.git
-          $ cd swagger-codegen
-          $ mvn package
-          $ java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
-    -i [URL or file path to JSON swagger API spec] \
-    -l akka-scala \
-    -c /path/to/config/file.json \
-    -o /path/to/output/folder
-
-Bang, all done. Run the `autodoc` script in the `bin` directory to see the API
-you just built.
