+# Account Configuration
+
+The two types of accounts, [admin](#admin-accounts) and
+[competitor](#competitor-accounts) can be specified using the toml array
+syntax.
+
+Competitor accounts and admin accounts must not have the same names.
+
+```toml
+[[accounts.admins]]
+name = "Host"
+password = "HostP@ssword1"
+
+[[accounts.competitors]]
+name = "Team1"
+password = "Team1P@ssword"
+
+[[accounts.competitors]]
+name = "Team2"
+password = "Team2P@ssword"
+```
+
+## Admin Accounts
+
+Admin accounts have access to the host view when using the basalt app
+and can manage the competition at run time.
+
+## Competitor Accounts
+
+Competitor accounts have access to the competitor view when using the
+basalt app and will test and submit their solutions.
+
+## Imports
+
+Account configuration may be imported from another toml file.
+
+```toml
+# In config.toml
+accounts = { import = "./accounts.toml" }
+```
+
+```toml
+# In accounts.toml
+[[admins]]
+name = "Host"
+password = "HostP@ssword1"
+
+[[competitors]]
+name = "Team1"
+password = "Team1P@ssword"
+
+[[competitors]]
+name = "Team2"
+password = "Team2P@ssword"

+# Configuration
+
+The configuration of basalt is written using [toml].
+This configuration is used by the [`basalt-cli`] and the [`basalt-server`]
+to host a competition.
+
+[toml]: https://toml.io/en/v1.0.0
+[`basalt-cli`]: https://github.com/basalt-rs/basalt-cli
+[`basalt-server`]: https://github.com/basalt-rs/basalt-server
+
+The configuration is broken up into four main sections:
+
+- [Runtime Config](./runtime.md)
+- [Setup Config](./setup.md)
+- [Language Config](./languages.md)
+- [Account Config](./account.md)
+- [Packet Config](./packet.md)
+
+## Example
+
+An example configuration is shown below.
+
+```toml
+# Host competition on port 1234
+port = 1234
+
+# Setup configuration
+[setup]
+# Install `opam` package
+install = '''
+apt-get install opam
+'''
+
+# Initialise opam so we can run ocaml
+init = '''
+opam init -y
+eval $(opam env)
+'''
+
+# Language configuration
+[languages]
+# Enable python3 default
+python3 = "*"
+# Enable built-in Java 21
+java = "21"
+# Add custom `ocaml` language type
+[languges.ocaml]
+build = "ocamlc -o out {{SOURCEFILE}}"
+run = "./out"
+
+
+# Account configurations
+[[accounts.admins]]
+name = "Host"
+password = "HostP@ssword1"
+
+[[accounts.competitors]]
+name = "Team1"
+password = "Team1P@ssword"
+

+name = "Team2"
+password = "Team2P@ssword"

+surpassing the capabilities of the average computer
+science student. Be wary as these problems will
+certainly give you great intellectual trouble. There

+science.
+

+luck. You will be rewarded for swiftness in your answers.

+# string
+[[packet.problems]]

+
+## Imports
+
+Because these configuration files can easily become out of hand, we
+offer the ability to import sections of the file using `import`.
+
+This example shows many sections broken into their own files.  Of
+course, if only want to take certain sections out, you may.
+
+```toml
+# In config.toml
+
+port = 1234 # Host competition on port 1234
+
+setup = { import = "./setup.toml" }
+languages = { import = "./languages.toml" }

+## Problems
+
+The `problems` array contains all of the problems that will be presented
+to the user in packet.
+
+- `title` - the title of this problem, this will also be used as a preview
+  in the UI.
+- `description` - Detailed description of this problem, supports Markdown
+- `supported_languages` - Optional list of languages that are allowed
+  for this problem.  All languages must appear in the [Languages
+  configuration](./languages.md).
+
+### Tests
+
+Each problem contains a suite of tests that will be used to validate the
+code that the competitor has submitted.
+
+- `input` - Input that will be provided to the competitor's program
+  through standard input
+- `output` - Expected output that the competitor's code should produce
+  out to standard output
+- `trim_output` - Whether the output should be have starting and trailing
+  whitespace removed before comparing.  i.e., `" hello "` would match
+  `"hello"`
+- `visible` - Whether this test should be visible to the user.  The
+  first visible test listed will be shown as an example in the problem
+  description.
+
+## Imports
+
+Many items in the packet spec may be imported from neighbouring files.
