+# Dependencies
+
+To run the Fuel indexer, you'll need to install a few dependencies on your system:
+
+- [`fuelup`](./fuelup.md), the Fuel toolchain manager
+- a supported [database](./database.md)
+  - We support Postgres at this time
+- the [`wasm32-unknown-unknown`](./wasm.md) Rust compilation target
+- [`wasm-snip`](./wasm.md), a utility for trimming WebAssembly binaries
+
+If you don't want to install a database directly onto your system, you can use Docker to run it as an isolated container. You can install it by following the [install instructions](https://docs.docker.com/get-docker/). For reference purposes, we provide a [`docker compose` file](https://github.com/FuelLabs/fuel-indexer/blob/master/scripts/docker-compose.yaml) that runs a Postgres database and the Fuel indexer service.
+
+Also, it's assumed that you have the Rust programming language installed on your system. If that is not the case, please refer to the [Rust installation instructions](https://www.rust-lang.org/tools/install) for more information.

 # Database
 
-The Fuel indexer uses [Postgres](https://github.com/docker-library/postgres/blob/2f6878ca854713264ebb27c1ba8530c884bcbca5/14/bullseye/Dockerfile) as the primary database.

-  - How to use different data types from your Sway contract, all the way to your Postgres table
 - [Foreign Keys](./foreign-keys.md)
-  - How foreign keys are handled in GraphQL schema, and Postgres.

 # GraphQL
 
+The Fuel indexer uses GraphQL to in order to allow users to query for indexed data. Please note that the Fuel indexer does not support the full GraphQL specification; however, we do our best to reasonably support as much as we can. In this chapter, you can find information on how to leverage our supported features to efficiently get the data you want.
