Once you have downloaded the source, you should have a series of folders inside of the dhis2-docbook-docs directory. All documents should be placed in the dhis2-docbook-docs/src/docbkx/XX folder. Note that the XX represents the ISO 639-1 (two-letter) language code of the documentation. If you are developing English language documentation, place it inside the /dhis2-docbook-docs/src/docbkx/en/ folder. Place any image files that may be linked to your document in the /dhis2-docbook-docs/src/docbkx/XX/resources/images folder and link these inside your DocBook document using a relative file link. When the documentation is built, in a separate step, the images will be automatically copied over to the correct directory during the build process.
