+# How do I add build automation to the project?
+
+## FAKE
+[Fake](https://fake.build/) is a DSL for build tasks that is modular, extensible and easy to start with. Fake allows you to easily build, bundle, deploy your app and more by executing a single command.
+
+> The standard template comes [with a FAKE project](../../../template-safe-commands) by default, so **this recipe only applies to the minimal template**.
+
+---
+#### 1. Create a build project
+
+Create a new console app called 'Build' at the root of your solution
+
+```fsharp
+dotnet new console -lang f# -n Build -o .
+```
+
+> We are creating the project directly at the root of the solution in order to allow us to execute the build without needing to navigate into a subfolder.
+
+#### 2. Create a build script
+
+Open the project you just created in your IDE and rename the module it contains from `Program.fs` to `Build.fs`.
+
+This renaming isn't explicitly necessary, however it keeps your solution consistent with other SAFE apps and is a better name for the file really.
+
+> If you just rename the file directly rather than in your IDE, then the Build project won't be able to find it unless you edit the Build.fsproj file as well
+
+Open `Build.fs` and paste in the following code.
+
+```fsharp
+open Fake.Core
+open Fake.IO
+open System
+
+let redirect createProcess =
+    createProcess
+    |> CreateProcess.redirectOutputIfNotRedirected
+    |> CreateProcess.withOutputEvents Console.WriteLine Console.WriteLine
+
+let createProcess exe arg dir =
+    CreateProcess.fromRawCommandLine exe arg
+    |> CreateProcess.withWorkingDirectory dir
+    |> CreateProcess.ensureExitCode
+
+let dotnet = createProcess "dotnet"
+
+let npm =
+    let npmPath =
+        match ProcessUtils.tryFindFileOnPath "npm" with
+        | Some path -> path
+        | None -> failwith "npm was not found in path."
+    createProcess npmPath
+
+let run proc arg dir =
+    proc arg dir
+    |> Proc.run
+    |> ignore
+
+let execContext = Context.FakeExecutionContext.Create false "build.fsx" [ ]
+Context.setExecutionContext (Context.RuntimeContext.Fake execContext)
+
+Target.create "Clean" (fun _ -> Shell.cleanDir (Path.getFullName "deploy"))
+
+Target.create "InstallClient" (fun _ -> run npm "install" ".")
+
+Target.create "Run" (fun _ ->
+    run dotnet "build" (Path.getFullName "src/Shared")
+    [ dotnet "watch run" (Path.getFullName "src/Server")
+      dotnet "fable watch --run npx vite" (Path.getFullName "src/Client") ]
+    |> Seq.toArray
+    |> Array.map redirect
+    |> Array.Parallel.map Proc.run
+    |> ignore
+)
+
+open Fake.Core.TargetOperators
+
+let dependencies = [
+    "Clean"
+        ==> "InstallClient"
+        ==> "Run"
+]
+
+[<EntryPoint>]
+let main args =
+  try
+      match args with
+      | [| target |] -> Target.runOrDefault target
+      | _ -> Target.runOrDefault "Run"
+      0
+  with e ->
+      printfn "%A" e
+      1
+```
+
+#### 3. Add the project to the solution
+
+Run the following command
+
+```bash
+dotnet sln add Build.fsproj
+```
+#### 4. Installing dependencies
+
+You will need to install the following dependencies:
+
+```
+Fake.Core.Target
+Fake.IO.FileSystem
+```
+
+We recommend migrating to [Paket](https://fsprojects.github.io/Paket/).
+It is possible to use FAKE without Paket, however this will not be covered in this recipe.
+
+#### 5. Run the app
+
+At the root of the solution, run `dotnet paket install` to install all your dependencies.
+
+If you now execute `dotnet run`, the default target will be run. This will build the app in development mode and launch it locally.
+
+To learn more about targets and FAKE in general, see [Getting Started with FAKE](https://fake.build/guide/getting-started.html#Minimal-Example).
