+# Accounts
+
+## Sessions
+
+A session represents a single 'log in' for a scratch account.
+
+The session object:
+```json
+{
+  "username": "faretek1",
+  "id": "..."
+}
+```
+
+### `scratch login`
+
+Login to a scratch account and add it to the current group. You will be prompted for a username and password
+
+### `scratch login --sessid`
+
+Login to a scratch account and add it to the current group. You will be prompted for a session ID.
+
+## Account groups
+
+The CLI allows you to configure account groups. These are collections of 1+ accounts which you can perform actions with.
+
+The group object:
+```json
+{
+  "name": "FA",
+  "sessions": [
+    {
+      "username": "faretek1",
+      "id": "..."
+    },
+    {
+      "username": "faretek",
+      "id": "..."
+    }
+  ]
+}
+```
+
+These are stored in the cookies as values for an object, not a list. The key is the name but lowercase.
+
+### `scratch ungroup`
+
+This exits the current group and into the 'global' group. If you login now, it will make a new group with only 1 member.
+
+### `scratch group`
+
+Get the members of the group.

+# Scratch CLI
+
+!!! Warning
+
+    This documentation currently does not apply. It is currently documenting a specification for the tool.
+
+The [Scratch CLI](https://github.com/scratch-api/scratch-cli) is a command line client for scratch that wraps 
+scratchattach.
+
+## Why Scratch CLI?
+
+Scratch CLI is built to be good for account management. It makes it easy to:
+
+- Switch between accounts
+- Perform actions with multiple accounts
+- Manage certain groups of accounts
