There are some questions we need to ask ourselves before starting to write a new recipe:

• Where is the source code stored?
• Is it source-controlled or released as a tarball?
• What is the source code license?
• What build system is it using?
• Does it need configuration?
• Can we cross-compile it as it is, or does it need to be patched?
• What files need to be deployed to the root filesystem, and where do they go?
• Are there any system changes that need to happen, such as new users or
  init scripts?
• Are there any dependencies that need to be installed into sysroot beforehand?

Once we know the answers to these questions, we are ready to start writing our recipe.
