+# Setting up an OxCaml project
+
+As an example of how to add custom repositories and pin dependencies in projects
+using Dune Package Management, let's look at setting up a basic OxCaml project.
+[OxCaml](https://oxcaml.org/) is a compiler branch with fast moving set of
+extensions to OCaml. Some tweaks are required to set up a project that compiles
+with OxCaml when using dune package management.
+
+## Setting up the `dune-workspace`
+
+OxCaml has a custom `opam-repository` that provides compatible dependencies.
+This is specified in the `dune-workspace`.
+
+```{code-block} dune
+(lang dune 3.20)
+
+(pkg enabled)
+
+(repository
+ (name oxcaml)
+ (url git+https://github.com/oxcaml/opam-repository))
+
+(lock_dir
+ (repositories overlay oxcaml upstream))
+```
+
+In the `dune-project`, we also need to add a constraint to depend on the OxCaml
+compiler. Otherwise, the solver may pick up the latest upstream compiler, which
+does not support the OxCaml extensions.
+
+```{code-block} dune
+(lang dune 3.20)
+
+(package
+ (name hello-oxcaml)
+ (depends
+  (ocaml-variants
+   (= 5.2.0+ox))))
+```
+
+Let's add a test program that uses OxCaml syntax.
+
+::::{dropdown} `main.ml`
+:icon: file-code
+
+:::{literalinclude} oxcaml/main.ml
+:language: dune
+:::
+
+::::
+
+And to build it, we add a `dune` file.
+
+```{code-block} dune
+(executable
+ (public_name main))
+```
+
+## Building the project
+
+As usual, let's build the project with:
+
+```
+$ dune exec ./main.exe
+...
+43
+```
+We have successfully built the project with the OxCaml compiler and run the executable.
+
+## Developer tools
+
+Note that OxCaml provides its own forks of the developer tools
+`ocaml-lsp-server`, `ocamlformat`, etc. Make sure to include constraints for the
+tools in the `dune-workspace` if you intend to use them for your development
+workflows.
+
+For `ocamlformat` it would look something like this:
+
+```{code-block} dune
+
+(lang dune 3.20)
+
+(pkg enabled)
+
+(repository
+ (name oxcaml)
+ (url "git+https://github.com/oxcaml/opam-repository"))
+
+(pin
+ (name ocamlbuild)
+ (url "git+https://github.com/Sudha247/ocamlbuild#oxcaml+dune")
+ (package
+   (name ocamlbuild)
+   (version 0.15.0+ox)))
+
+(pin
+ (name odoc-parser)
+ (url "git+https://github.com/Sudha247/odoc#replace-symlinks")
+ (package
+   (name odoc-parser)
+   (version 3.1.0+ox)))
+
+(lock_dir
+ (path "dune.lock")
+ (repositories :standard oxcaml))
+
+(lock_dir
+ (path "dev-tools.locks/ocamlformat")
+ (pins ocamlbuild)
+ (constraints
+   (ocaml-lsp-server (= 1.19.0+ox))
+   (ocaml-variants (= 5.2.0+ox)))
+ (repositories overlay oxcaml upstream))
+```
+
+Observe that this includes pins to dependencies `ocamlbuild` and `odoc-parser` as they are required by the OxCaml version of `ocamlformat`.
