 If you'd like to work on an issue, please comment on it to let the maintainers know, so that they can assign it to you. If someone else has already commented and taken up that issue, please refrain from working on it and submitting a PR without asking the maintainers as it leads to unnecessary duplication of effort.

-## Writing Commit Messages
-
-Good commit messages serve at least three important purposes:
-
-* They speed up the reviewing process.
-* They help us write good release notes.
-* They help future maintainers understand your change and the reasons behind it.
-
-Structure your commit message like this:
-
- ```
- Short (50 chars or less) summary of changes ( involving Fixes #Issue-number keyword )
-
- More detailed explanatory text, if necessary. Wrap it to about 72
- characters or so. In some contexts, the first line is treated as the
- subject of an email and the rest of the text as the body. The blank
- line separating the summary from the body is critical (unless you omit
- the body entirely); tools like rebase can get confused if you run the
- two together.
-
- Further paragraphs come after blank lines.
-
-   - Bullet points are okay, too
-
-   - Typically a hyphen or asterisk is used for the bullet, preceded by a
-     single space, with blank lines in between, but conventions vary here
- ```
-
-* Write the summary line and description of what you have done in the imperative mode, that is as if you were commanding someone. Start the line with "Fix", "Add", "Change" instead of "Fixed", "Added", "Changed".
-* Always leave the second line blank.
-* Be as descriptive as possible in the description. It helps reasoning about the intention of commits and gives more context about why changes happened.
-
-## Tips
-
-* If it seems difficult to summarize what your commit does, it may be because it includes several logical changes or bug fixes, and are better split up into several commits using `git add -p`.

 ## Installation
-Follow the [installation guide](https://github.com/processing/p5.js-web-editor/blob/master/developer_docs/installation.md).
+Follow the [installation guide](./installation.md).
+
+## Development Workflow
+This project uses git-flow. For an in-depth overview of git-flow, read ["A successful Git branching model"](https://nvie.com/posts/a-successful-git-branching-model/). As a person contributing code but not creating production releases (this is most people!), here's what you need to know:
+* The default branch is `develop`. All pull requests should be made to this branch. It should be stable, and all commits are visible at a staging sever.
+* When working on a bug or feature, you should branch from the `develop` branch. When you're done, you should open a pull request from your feature branch to `develop`.
+* The `release` branch is the live production branch, and is the code deployed to editor.p5js.org. Changes to this branch should be made carefully, and will be done using git tags. 
+* Emergency hotfix changes should be branched from `release` and merged via a pull request to `release`. After a PR is merged, then the commits can be merged to `develop`.
+
+See the [release guide](./release.md) for information about creating a release.
 
 ## Tests
 To run the test suite simply run `npm test` (after installing dependencies with `npm install`)
 
 A sample unit test could be found here: [Nav.test.jsx](../client/components/__test__/Nav.test.jsx).
