Converting an existing project to Hog means: copying the source files into a git repository, adding Hog as a submodule, creating the Hog list files (text files containing the names of your source files), and writing a `hog.conf` file, storing the project's properties.

### Does Hog support HLS in Vivado?
Our idea is to store in the HDL repository only the files required to build the project. Therefore, for HLS, we suggest keeping the C++ code in another repo, and then commit to the HDL repository the resulting user IPs and the `.xci` file. For more details on how to work with user IPs in Vivado, have a look at the [User IP Chapter](../02-User-Manual/01-Hog-local/12-User-IPs.md).
