+    \title Setting Up Nimble
+
+    \l {https://github.com/nim-lang/nimble#readme}{Nimble} is a package
+    manager for the Nim programming language. It is delivered with
+    \l{https://nim-lang.org/}{Nim} and uses the Nim compiler to generate
+    executables that are supported on Windows, Linux, and \macos.
+
+    To use \QC for Nim development, you need to enable the experimental
+    Nim plugin. Select \uicontrol Help > \uicontrol {About Plugins} >
+    \uicontrol {Other Languages} > \uicontrol Nim, and then restart \QC.
+
+    In addition, you have to download and install Nim and set up a Nim kit
+    in \QC.
+
+    You can use wizards to create Nim and Nimble projects.
+
+    \section1 Setting Up the Development Environment
+
+    To configure \QC to build Nim executables:
+
+    \list 1
+        \li Select \uicontrol Tools > \uicontrol Options > \uicontrol Kits
+            \uicontrol Compilers > \uicontrol Add > \uicontrol Nim to specify
+            the path to the the Nim compiler.
+        \li Select \uicontrol Apply to add the compiler.
+        \li Select \uicontrol Kits > \uicontrol Add to add a kit for building
+            applications with Nimble:
+            \image qtcreator-kit-nimble.png "Nimble kit"
+            \list 1
+                \li In the \uicontrol Name field, specify a name for the kit.
+                \li In the \uicontrol Compiler group, \uicontrol Nim field,
+                    select the Nim compiler you added above.
+                \li Select \uicontrol Apply to add the kit.
+            \endlist
+    \endlist
+
+    \section1 Creating Nimble Applications
+
+    To use a wizard to create boilerplate files for a Nim package that is
+    managed with Nimble:
+
+    \list 1
+        \li Select \uicontrol File > \uicontrol {New File or Project} >
+            \uicontrol Projects > \uicontrol {Non-Qt Project} >
+            \uicontrol {Nimble Application}.
+        \li Specify the name and location of the application.
+        \li Select \uicontrol Next.
+        \li Specify information about your application package.
+            \image qtcreator-project-nimble.png
+        \li Select \uicontrol Next to create the project.
