+# Usage of Proclamation to maintain changelogs
+
+This file:
+
+```txt
+SPDX-License-Identifier: CC0-1.0
+SPDX-FileCopyrightText: 2020 Collabora, Ltd. and the Proclamation contributors
+```
+
+This project uses the [Proclamation][] tool to maintain changelogs. Contributors
+to this project do not need to use Proclamation, but they are asked to write a
+fragment for the changelog describing their change. See below for more details.
+
+- Directory to run Proclamation in: `doc/changes`
+  - Config file: default name (`.proclamation.json`)
+- Location of the per-changelog-section directories: `doc/changes`
+
+[Proclamation]: https://gitlab.com/ryanpavlik/proclamation

+
+## Quick Start Instructions for Contributors
+
+- Get a merge/pull request number for your change: this might involve pushing it
+  as a WIP.
+- Create a file in the appropriate section's directory, named `mr.YOURNUMBER.md`
+- In that file, briefly describe your change as you would like it describe in
+  the changelog for the next release.
+- If your changes affect multiple sections, you can have a file in each section
+  describing the section-specific changes.
+- If your change resolves an issue or otherwise references some issue or
+  merge/pull request, you can add those references to the beginning of your
+  changelog fragment. See the full instructions below regarding
+  [References](#references).
+
+## About Proclamation and Usage Instructions
+
+The "Proclamation" tool assembles changelogs, which incorporate fragments of
+changelog text added by the author of a change in a specific location and
+format.
+
+### Fragments
+
+Each change should add a changelog fragment file, whose contents are
+Markdown-formatted text describing the change briefly. Reference metadata will
+be used to automatically add links to associated issues/merge requests/pull
+requests, so no need to add these in your fragment text. The simplest changelog
+fragment just contains one line of Markdown text describing the change:
+
+```md
+Here the author of a change has written some text about it.
+```
+
+(If you change the template in your Proclamation config file, your project can use a different markup format than Markdown.)
+
+### References
+
+The changelog fragment system revolves around "references" - these are issue
+reports, pull requests, or merge requests associated with a
+change. Each fragment must have at least one of these, which forms the main part
+of the filename. If applicable, additional can be added within the file - see
+below for details.
+
+This portion of the Proclamation system is intentionally left very flexible,
+since there are very many ways of organizing and managing a project. By default,
+references are delimited by the `.` character. The first two fields have some
+conventional meaning, while any additional fields are up to the user and are
+only used if a custom template is supplied by a project.
+
+The format of references in general is:
+
+```txt
+<ref_type>.<number>
+```
+
+where
+
+- `ref_type` is "issue", "mr", or "pr"
+- `number` is the issue, MR, or PR number
+- any additional `.`-delimited tokens are passed on to the template in the
+  `service_params` list.
+
+Your changelog fragment filename is simply the "main" reference with the `.md`
+extension added. (You can also use `.rst` or `.txt` as your extension in your
+project.)
+
+To specify additional references in a file, prefix the contents of the changelog
+fragment with a block delimited above and below by `---`, with one reference on
+each line. (This can be seen as a very minimal subset of "YAML Front Matter", if
+you're familiar with that concept.) For example:
+
+```md
+---
+- issue.35
+- mr.93
+---
+Here the author of a change has written some text about it.
+```
+
+There are provisions for providing your own reference parser if this format is
+entirely unusable, but they're underdeveloped. (Most use cases found by the
+original author can actually be accommodated just by changing the template and
+specifying `.`-delimited fields in references.) If this functionality is
+interesting to you, get involved in the development of Proclamation and help
+finish it!
+
+### Sections
+
+Changelog fragments are organized into sections, each of which should have its
+own directory. These might be "type-of-change" sections (e.g. new feature,
+bugfix, etc). Alternately, they might be logical sub-projects - it's permissible
+to have multiple projects configured in one config file and repo with
+partially-overlapping sections. (This is actually a part of one of the
+originally motivating use cases for this tool.)
+
+Every file whose filename parses and meets some basic checks will be used! (You
+do need to add e.g. an `.md` file extension to files for them to parse as
+references.) Having a `changes/your_section_name` directory for each section is
+recommended. You can provide a `README.md` file with a modified subset of this
+file in that directory, as guidance to contributors to your project.
+(`README.md` won't parse as a reference, so it will not be treated as a
+changelog fragment.)
+
+Use whatever works for your project. Right now, all changelog fragments must be
+in a section, sections must be a single directory, and sections may not be
+nested. If you'd like to loosen these assumptions, get involved in the development of Proclamation and help!
+
+## Configuration
+
+Your project should have a configuration file: the default name is
+`.proclamation.json`. The top level object can either be a project config object
+directly, or contain a member named "projects" with an array of project config
+objects.
+
+You can look at the config file for this project for guidance, since it's a
+pretty simple use case of this tool. (Proclamation was designed to handle more
+elaborate use-cases than this.)
+
+- Project attributes:
+  - `project_name` - Required. Used to form the heading in the default template,
+    etc.
+  - `base_url` - Technically optional, but required if you're using the default
+    template. Passed to the template which may use it to form reference links.
+  - `news_filename` - Optional, in case your changelog isn't called NEWS.
+  - `sections` - Required: contains an object. The key names are the section
+    names (used by the default template for section headers), while the values
+    are objects. Sections might be logical sub-projects, or alternately
+    categories of changes (feature, bug fix, etc), it's up to you.
+    - The only key valid right now in the child of the section is `directory`,
+      which indicates the directory to search for changelog fragments.
+  - `template` - Optional. The name of a Jinja2 template for a single release's
+    changelog section. `base.md` comes with Proclamation and is used by default.
+    Your custom template might inherit from this if you only need to change a
+    few small details. Evaluated relative to the current working directory when
+    you run Proclamation.
+  - `insert_point_pattern` - Useful mainly if you're not using the default
+    template. The first match of this regex will be considered the first line of
+    a release entry, and your new release will be put in your changelog file
+    above it. Default works with the default template (looks for a second-level
+    Markdown heading).
+  - `extra_data` - Any extra data you'd like to pass along to your custom
+    template.
+
+## Sample Usage Workflow
+
+Note that the base `proclamation` script and all its subcommands have help,
+accessible through `-h` or `--help`. The guidance in this section of the README
+is intentionally minimal, to avoid contradicting the online help which remains
+up-to-date implicitly. This is also only the simplest, minimal way to perform
+these operations: if your project is more complex, there may already be more
+features to support your needs in the command line help.
+
+### During Development
+
+As changes get submitted to your project, have each change author create a
+changelog fragment file. Since these are all separate files, with names made
+unique by your issue/repo tracker, there won't be merge conflicts no matter what
+order they're merged in. (This is the central benefit of Proclamation, and its
+inspiration, towncrier, over having each contributor edit CHANGES as part of
+their submission.)
+
+At any time you can run `proclamation draft` to preview the release portion that
+would be added to your changelog if you released at that time.
+
+### Preparing for a Release
+
+When you're ready to perform a release, you'll want to run Proclamation to
+update your changelog, then remove the fragments that you've incorporated into
+the regular changelog. You can use a command like the following:
+
+```sh
+proclamation build YOUR_NEW_VERSION
+```
+
+to preview the full file on screen. When you're ready to actually perform the
+update, run something like:
+
+```sh
+proclamation build YOUR_NEW_VERSION --delete-fragments --overwrite
+```
+
+to overwrite your changelog file with the updated one and delete the used
+changelog fragments.
+
+You're welcome to manually edit the new (or old!) changelog entries as desired:
+as long as the `insert_point_pattern` (by default, `^## .*`) can still match,
+Proclamation will not be confused.
+
+Finally, make sure the deletion of the fragments and the update of the changelog
+has been checked in to your version control system.
