Build the docs

The documentation source files are under the ../content directory in the corda-docs repository, and is written in markdown format.

The documentation output in HTML format is generated using Hugo. You can build the docs locally in seconds once you have set up your environment (see below).

Build the docs locally

Steps:

  1. Download Visual Studio Code or a markdown editor of your choice ( atom, for example).
  2. If you’ve already installed Hugo, check your version. If the result is not v0.65 or later, or if you don’t see Extended, you’ll need to download the latest extended version of Hugo (for example, hugo_extended_0.74.3_Linux-64bit.tar.gz).
  3. Ensure the Hugo binary is on your PATH.
  4. Fork the corda-docs repository and ensure it is added as the upstream remote in your fork.
  5. Clone your fork locally.
  6. Open a console / command prompt window and navigate (cd) to the root directory of the fork repo.
  7. Run hugo serve.
  8. Open the local docs site build on http://localhost:1313 (or whatever it says in the console) in your browser.
  9. Edit the documentation source files in markdown - all source files are in the ../content directory in the repo structure. Each edit triggers an immediate page update on http://localhost:1313.

Contribute to documentation updates

To propose an update to the public released Corda docs, fork the corda-docs repository, make your changes, and submit a pull request targeting the master branch in the upstream repository from your fork.

Steps

  1. Fork the corda-docs repository and add it as upstream (or sync your existing fork with the upstream repo’s master branch - see below for instructions).
  2. Edit the documentation files in a new branch in your fork.
  3. Commit and push the changes to your fork.
  4. Create a pull request targeting the master branch in the upstream repo. Your pull request will be auto-assigned to R3’s technical writing team for review.

Where are the files

The documentation for all released versions of Corda OS, Corda Enterprise, and Corda Enterprise Network Manager (CENM) are organised in sub-directories, following the product flavour and then the version.

For example:

../corda-docs/content/en/docs/corda-os/4.7

Edit web pages directly in Visual Studio Code

After installing Hugo and Visual Studio Code, run the following commands per operating system.

Windows Powershell (assuming there are no spaces in your directory names):

.\serve_and_edit.ps1

Mac/Linux:

make local-serve-and-edit

Or if you want to use Docker:

hugo-serve-and-edit

As a result, there will be an extra icon in the title bar of your local docs site, which should open the current page in Visual Studio Code:

Visual Studio Code

Edit web pages directly in Atom

After installing Hugo and Atom (you need to install the open package!), run the following commands per operating system.

If this is your preferred editor, then consider setting HUGO_PARAMS_EDITOR in your environment.

Windows Powershell:

$env:HUGO_PARAMS_EDITOR="atom"
.\serve_and_edit.ps1

Mac/Linux:

export HUGO_PARAMS_EDITOR=atom
make local-serve-and-edit

Or if you want to use Docker:

export HUGO_PARAMS_EDITOR=atom
make hugo-serve-and-edit

Keep your fork in sync with the upstream repo

To best way to keep your fork in sync with the upstream (original) repository is to add it as the upstream repo after you create the fork.

Add the upstream repo

To add upstream:

cd <to-your-fork-repo-dir>
git remote add upstream git://github.com/corda/corda-docs.git

You would normally only need do this once after you create the fork.

If you are not using an ssh key to access GitHub, use the https URL instead:

git remote add upstream https://github.com/corda/corda-docs.git

If you’ve got the upstream repo URL wrong, you can change the upstream repo URL using the following command:

git remote set-url upstream https://github.com/corda/corda-docs.git

View your remotes

To view your remotes:

git remote -v

You should see something like this:

git remote -v

origin	git@github.com:my-github-username/corda-docs.git (fetch)   # YOUR FORK
origin	git@github.com:my-github-username/corda-docs.git (push)
upstream	git@github.com:corda/corda-docs.git (fetch)      # THE ORIGINAL REPO
upstream	git@github.com:corda/corda-docs.git (push)

Alternatively, if you are accessing GitHub without an ssh key:

git remote -v

origin	https://github.com/my-github-username/corda-docs.git (fetch)   # YOUR FORK
origin	https://github.com/my-github-username/corda-docs.git (push)
upstream	https://github.com/corda/corda-docs.git (fetch)      # THE ORIGINAL REPO
upstream	https://github.com/corda/corda-docs.git (push)

Remove the upstream repo

If you need to remove the upstream repo for any reason:

git remote rm upstream

Keep the upstream repo updated

To keep the upstream updated (in other words, to fetch all the stuff from the upstream repo):

git fetch upstream

Sync your fork

There are two ways in which you can do this - merge or rebase.

Merge the upstream with your fork

To sync your fork via merge:

git merge upstream/master master

This command will merge the latest changes from the master branch of the upstream into your local fork’s master branch.

To merge a different branch, replace master with the name of that branch for both repos.

For example, to merge a branch called example-branch, run the following:

git checkout example-branch
git merge upstream/example-branch example-branch

Rebase the upstream with your fork

git rebase upstream/master

To rebase a different branch, replace master with the name of that branch for both repos.

For example, to rebase a branch called example-branch, run the following:

git checkout example-branch
git rebase upstream/example-branch example-branch

Push from the local fork master to the origin fork master

After the merge or rebase, don’t forget to push your local fork’s master branch (or another branch you’ve synced) to the fork origin master (or another corresponding branch).

For example:

git push origin master
