Editing Tindallgrams

The biggest task by far is editing the Tindallgrams themselves. To contribute in this way, first find a Tindallgram that needs to be edited in one of the sources. Fork the repository, add your edited text and issue a pull request. You can find many guides to this workflow on the internet.

Every Tindallgram should be in a Markdown file with the extension .md and a name exactly matching (including case) the “serial” of the Tindallgram. For example, the text of “66-FM1-100” would go in a file named

Each file needs some Jekyll front matter, including at least layout, date, from, serial and subject. layout for all Tindallgrams must be tindallgram (some other kinds of pages have different layouts). These other minimally required values come from the memos themselves. Again using 66-FM1-100 as an example:

layout: tindallgram
date: Aug 30 1966 
from: FM/Deputy Chief, Mission Planning and Analysis Division
serial: 66-FM1-100
subject: Notes regarding the AS-207/208 Guidance Systems Operation Plan (GSOP) meeting with MIT

The body of the Tindallgram should then follow, in Markdown format, though very little formatting is required beyond blank lines between paragraphs.

Line breaks

Put line breaks where they occur in the original. This will not be reflected in the online versions, but at least the markdown files will reflect the originals in this way if that ever becomes important to somebody. When a word is hyphenated at the end of a line, remove the hyphen, recombine the word and place a line break after.

Signatures, handwritten notes, and adressees

Do not include Tindall’s signature or the sometimes included lists of addressees. Do not include indications of handwritten notes.

“Non-Tindall” material

A few memos by other people or attachments are included in the PDFs. Do not transcribe these. There is some interest in providing links in the edited Tindallgrams to the PDF sources. If this feature were added see Issue #4, perhaps we could provide an annotation in the transcribed version to see the attached material there.

Running a local copy

Since this uses Jekyll you will need ruby. To run a version on localhost:

$ bundle install
$ bundle exec jekyll build
$ bundle exec jekyll serve

You can then visit http://localhost:4000/ to view. There is one caveat: when running locally, you have to add .html to all URLs except for the index. For example the equivalent of on localhost has to be http://localhost:4000/66-FM1-59.html. This is annoying, so if anyone wants to take on Issue #20, that would be awesome.
