+# `juce.projucerHook` {#juce-projucer-hook}
+
+[Projucer](https://juce.com/tutorials/tutorial_new_projucer_project/) is a graphical project management utility and build system for the [JUCE](https://juce.com/) audio programming framework. It is available in nixpkgs under the `juce` package.
+
+The `juce.projucerHook` setup hook overrides the configure and install phases. It is only supported on Linux and requires your project's `.jucer` file to contain a `LinuxMakefile` exporter.
+
+## Example {#juce-projucer-hook-example}
+
+```nix
+{
+  juce,
+  stdenv,
+}:
+stdenv.mkDerivation {
+  # ...
+  nativeBuildInputs = [ juce.projucerHook ];
+
+  jucerFile = "Microbiome.jucer";
+
+  dontUseProjucerInstall = true;
+  # ...
+}
+```
+
+## Variables controlling `juce.projucerHook` {#juce-projucer-hook-variables}
+
+### `dontUseProjucerConfigure`
+
+Disables `projucerConfigurePhase`
+
+### `dontUseProjucerInstall`
+
+Disables `projucerInstallPhase`
