 # Expert
 
-**TODO: Add description**
+Welcome to the monorepo for the official Elixir LSP implementation, Expert!
 
-## Installation
+## Projects
 
-If [available in Hex](https://hex.pm/docs/publish), the package can be installed
-by adding `expert` to your list of dependencies in `mix.exs`:
+- `expert` - the LSP server
+- `engine` - the code intelligence engine injected into the user's project
+- `namespace` - mix task to disguise the engine application to not clobber the user's code
 
-```elixir
-def deps do
-  [
-    {:expert, "~> 0.1.0"}
-  ]
-end
+## Getting Started
+
+Expert uses the [just](https://just.systems) command runner system (similar to make). If you use [Nix](https://nixos.org/), you can jump in the dev shell `nix develop` and `just` and the rest of the dependencies will be installed for you.
+
+Otherwise, please install the following dependencies with your choice of package manager or with asdf/mise.
+
+- [just](https://just.systems)
+- Erlang (version found in the .tool-versions file)
+- Elixir (version found in the .tool-versions file)
+- Zig (version found in the .tool-versions file)
+- xz 
+- 7zz (to create Windows builds) 
+
+To quickly build a release you can run locally
+
+```shell
+# dev build
+just release-local
+
+# prod build
+MIX_ENV=prod just release-local
 ```
+Now a single file executable for your system will be available in `./expert/burrito_out/`, e.g., `./expert/burrito_out/expert_linux_amd64`
 
-Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
-and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
-be found at <https://hexdocs.pm/expert>.
+To start the local dev server in TCP mode.
 
+```shell
+just start --port 9000
+```
+
+The full set of recipes can be found by running `just --list`.
+
+```
+Available recipes:
+    compile project             # Compile the given project.
+    deps project                # Run mix deps.get for the given project
+    mix cmd *project            # Run a mix command in one or all projects. Use `just test` to run tests.
+    release-all                 # Build releases for all target platforms
+    release-local               # Build a release for the local system
+    release-plain               # Build a plain release without burrito
+    run project +ARGS           # Run an arbitrary command inside the given project directory
+    start *opts="--port 9000"   # Start the local development server
+    test project="all" *args="" # Run tests in the given project
+```
