An optional ``--user`` + argument will install them locally, but you have to add their location to + $PATH (pip will emit a warning). Alternatively, they can be installed + globally (but will probably require root privileges). + + .. note:: + Although not necessary, it is recommended you use a virtual environment. + More advanced usage instructions for *pip* are beyond the scope of this + document but you can refer to the `pip homepage`_ for detailed guides. + +- Optionally, the `Dia`_ application can be installed if you need to edit + existing ``.dia`` diagram files, or create new ones. + +An example set of installation commands for Ubuntu follows, assuming that the +working directory is ``docs``: + +.. code:: shell + + sudo apt install python3 python3-pip plantuml [dia] + pip3 install [--user] -r requirements.txt + +.. note:: + Several other modules will be installed as dependencies. Please review + the list to ensure that there will be no conflicts with other modules already + installed in your environment. + +Building rendered documentation +------------------------------- + +Documents can be built into HTML-formatted pages from project root directory by +running the following command. + +.. code:: shell + + make doc + +Output from the build process will be placed in: + +:: + + docs/build/html + +We also support building documentation in other formats. From the ``docs`` +directory of the project, run the following command to see the supported +formats. It is important to note that you will not get the correct result if +the command is run from the project root directory, as that would invoke the +top-level Makefile for |TF-A| itself. + +.. code:: shell + + make help + +Building rendered documentation from a container +------------------------------------------------ + +There may be cases where you can not either install or upgrade required +dependencies to generate the documents, so in this case, one way to +create the documentation is through a docker container. The first step is +to check if `docker`_ is installed in your host, otherwise check main docker +page for installation instructions. Once installed, run the following script +from project root directory + +.. code:: shell + + docker run --rm -v $PWD:/TF sphinxdoc/sphinx \ + bash -c 'cd /TF && \ + pip3 install plantuml -r ./docs/requirements.txt && make doc' + +The above command fetches the ``sphinxdoc/sphinx`` container from `docker +hub`_, launches the container, installs documentation requirements and finally +creates the documentation. Once done, exit the container and output from the +build process will be placed in: + +:: + + docs/build/html + +-------------- + +*Copyright (c) 2019, Arm Limited.
