 ### Before making changes
 
-WIP. Here we'll describe what the expected process and workflow is when making code changes, with regards to branching, forking and so on.
+1. If you are a contributor, you will need to create a fork of this repository
+   on your own GitHub handle, as you will not have commit access to the
+   forensic architecture repo.
+2. Create a new branch from _develop_ (not master or staging). The branch
+   should be prefixed with 'topic/' if you are intending to submit a feature
+   ('enhancement' tag in the issue), or with 'fix/' if you are fixing a bug
+   ('bug' tag in the issue).
+
+All of your commits go in this branch. When the feature/fix is complete, follow
+the instructions below to submit a PR for the branch.
 
 ### Submitting changes as Pull Requests
 
-WIP
+In order to submit a branch as a PR, you'll need to install the [Travis CLI](https://github.com/travis-ci/travis.rb). The documentation for this is a little shifty: if you're developing on a Mac, you can easily install it with `brew install travis`. The Travis CLI is necessary so that you can encrypt your service account credentials and use them while testing in Travis CI.
+
+To do this, you need to run one extra command before you push commits
+to a remote branch:
+```
+npm run travis-encrypt
+```
+This command encrypts your private key and service account email in .env in
+such a way that they can still be used while running tests on Travis' server.
+This command will add a commit to your branch that modifies the binary file
+.env.enc, and updates your Travis config accordingly. After running this
+command, you should be able to pass the pre-push check and run tests in the
+Travis server.

These fields refer to the credentials of a [Google service account](https://cloud.google.com/iam/docs/understanding-service-accounts). Google requires that developers create these when attempting to access their services programmatically, so that they can attribute requests to users. Service accounts also contain identity information, which means that asset owners can allow certain service accounts access to certain sheets, just as one might differentially grant certain users access to certain cloud assets.

+# Architecture
+
+![](datasheet-server-graphic.jpg)
+
+Datasheet Server uses the architecture diagrammed above to allow effective
+management of the sheets it represents.
+
+It exposes an API with four endpoints:
+ * `/:sheet/:tab/:resource` - the primary means of accessing data in the
+     server. The name of a sheet is specified in
+     [sheets_config.js](https://github.com/forensic-architecture/datasheet-server/blob/develop/src/sheets_config.js#L7).
+     Each tab on the sheet is in lower case, with spaces replaced by
+     underscores. The resource name is the same as the name of the blueprinter
+     specified for the tab is sheets_config.js.
+ * `/:sheet/:tab/:resource/:id` - when the resource is a list, items in the list
+     can be accessed individually as well.
+ * `/update` - when this route is queried with a GET request, each of the
+     fetchers in the server will update their models from the relevant sheet.
+ * `/blueprints` - a JSON object that represents all available sheets, tabs, and
+     resources in the server.
+
+# Controller
+The [controller](https://github.com/forensic-architecture/datasheet-server/blob/develop/src/lib/Controller.js)
+manages all of the fetchers in the server. Its `update` triggers the update
+mechanisms of all the `update`s in the fetchers it manages. Its `retrieve` and
+`retrieveFrag` methods find the appropriate fetcher, and trigger its 
+respectively named method. Its `bluerprints` method collects the blueprints
+from all fetchers, and presents them as a single list.
+
+# Fetcher
+The [fetcher](https://github.com/forensic-architecture/datasheet-server/blob/develop/src/lib/Fetcher.js)
+is the most complex component in datasheet server. Its responsiblity is to
+interface with a sheet, and store the data from that sheet in a model. It also
+makes information from that model available to the controller.
+
+# Model
+The model layer is an [interface](https://github.com/forensic-architecture/datasheet-server/blob/develop/src/models/Interface.js)
+that specifies how stored data must be made available to a fetcher. The
+implementation of the model layer ([StoreJson](https://github.com/forensic-architecture/datasheet-server/blob/develop/src/models/StoreJson.js)
+is one example) determines the time and space complexity of retrieval.
