+# Duplo (C/C++/Java Duplicate Source Code Block Finder)
+
+This project is found in GitHub: [https://github.com/dlidstrom/Duplo](https://github.com/dlidstrom/Duplo).
+
+## General Information
+
+Duplicated source code blocks can harm maintainability of software systems.
+Duplo is a tool to find duplicated code blocks in large C, C++, Java, C# and
+VB.Net systems.
+
+## Maintainer
+
+Duplo was originally developed by Christian
+M. Ammann and is now maintained and developed by Daniel
+Lidström.
+
+## Usage
+
+Duplo works with a list of files. You can either specify a file that contains the list of files, or you can pass them using `stdin`.
+
+Run `duplo --help` on the command line to see the detailed options.
+
+### Passing files using `stdin`
+
+```bash
+# unix
+> find . \( -iname "*.cpp" -o -iname "*.h" \) | docker run dlidstrom/duplo - out.txt
+
+# windows
+> Get-ChildItem -Include "*.cpp", "*.h" -Recurse | % { $_.FullName } | docker run dlidstrom/duplo - out.txt
+```
+
+`duplo` will write the duplicated blocks into `out.txt`.
+
+### Passing files using file
+
+`duplo` can analyze files specified in a separate file:
+
+```bash
+# unix
+> find . -type f \( -iname "*.cpp" -o -iname "*.h" \) > files.lst
+> docker run dlidstrom/duplo files.lst out.txt
+
+# windows
+> Get-ChildItem -Include "*.cpp", "*.h" -Recurse |  % { $_.FullName } | Out-File -encoding ascii files.lst
+> docker run dlidstrom/duplo.exe files.lst out.txt
+```
