+# A Make compiler for Mix
+
+[![Build Status](https://github.com/elixir-lang/elixir_make/workflows/CI/badge.svg)](https://github.com/elixir-lang/elixir_make/actions)
+[![Hex version](https://img.shields.io/hexpm/v/elixir_make.svg "Hex version")](https://hex.pm/packages/elixir_make)
+
+This project provides a Mix compiler that makes it straight-forward to use makefiles in your Mix projects.
+
+## Documentation
+
+API documentation is available at [https://hexdocs.pm/elixir_make](https://hexdocs.pm/elixir_make)
+
+## Usage
+
+The package can be installed by adding `elixir_make` to your list of dependencies in `mix.exs`:
+
+```elixir
+def deps do
+  [{:elixir_make, "~> 0.4", runtime: false}]
+end
+```
+
+Still in your `mix.exs` file, you will need to add `:elixir_make` to your list of compilers in `project/0`:
+
+```elixir
+compilers: [:elixir_make] ++ Mix.compilers,
+```
+
+And that's it. The command above will invoke `make` for Unix, `nmake` for Windows and `gmake` for FreeBSD and OpenBSD. A "Makefile" file is expected at your project root for Unix systems and "Makefile.win" for Windows systems. Run `mix help compile.elixir_make` for more information and options.
+
+## Publishing a package to Hex.pm
+
+When publishing a package to Hex.pm using `elixir_make` requires you to add
+any file (such as the Makefile and any source files) to the `files` option.
+See [the hex docs](https://hex.pm/docs/publish#adding-metadata-to-code-classinlinemixexscode)
+
+```elixir
+  defp package do
+    [
+      # ...
+      files: [
+        "lib", "LICENSE", "mix.exs", "README.md", # These are the default files
+        "src/*.[ch]", "Makefile"], # You will need to add something like this.
+      # ...
+    ]
+  end
+```
+
+## License
+
+Same as Elixir.

+
+  This task runs `make` in the current project; any output coming from `make` is

+
+  ## Configuration
+
+  This compiler can be configured through the return value of the `project/0`
+  function in `mix.exs`; for example:
+
+      def project() do
+        [app: :myapp,
+         make_executable: "make",
+         make_makefile: "Othermakefile",
+         compilers: [:elixir_make] ++ Mix.compilers,
+         deps: deps()]
+      end
+
+  The following options are available:
+
+    * `:make_executable` - (binary or `:default`) it's the executable to use as the
+      `make` program. If not provided or if `:default`, it defaults to `"nmake"`
+      on Windows, `"gmake"` on FreeBSD, OpenBSD and NetBSD, and `"make"` on everything
+      else. You can, for example, customize which executable to use on a
+      specific OS and use `:default` for every other OS. If the `MAKE`
+      environment variable is present, that is used as the value of this option.
+
+    * `:make_makefile` - (binary or `:default`) it's the Makefile to
+      use. Defaults to `"Makefile"` for Unix systems and `"Makefile.win"` for
+      Windows systems if not provided or if `:default`.
+
+    * `:make_targets` - (list of binaries) it's the list of Make targets that
+      should be run. Defaults to `[]`, meaning `make` will run the first target.
+
+    * `:make_clean` - (list of binaries) it's a list of Make targets to be run
+      when `mix clean` is run. It's only run if a non-`nil` value for
+      `:make_clean` is provided. Defaults to `nil`.
+
+    * `:make_cwd` - (binary) it's the directory where `make` will be run,
+      relative to the root of the project.
+
+    * `:make_env` - (map of binary to binary) it's a map of extra environment
+      variables to be passed to `make`. You can also pass a function in here in
+      case `make_env` needs access to things that are not available during project
+      setup; the function should return a map of binary to binary. Many default
+      environment variables are set, see section below
+
+    * `:make_error_message` - (binary or `:default`) it's a custom error message
+      that can be used to give instructions as of how to fix the error (e.g., it
+      can be used to suggest installing `gcc` if you're compiling a C
+      dependency).
+
+    * `:make_args` - (list of binaries) it's a list of extra arguments to be passed.
+
+  The following options configure precompilation:
+
+    * `:make_precompiler` - a two-element tuple with the precompiled type
+      and module to use. The precompile type is either `:nif` or `:port`
+      and then the precompilation module. If the type is a `:nif`, it looks
+      for a DDL or a shared object as precompilation target given by
+      `:make_precompiler_filename` and the current NIF version is part of
+      the precompiled archive. If `:port`, it looks for an executable with
+      `:make_precompiler_filename`.
+
+    * `:make_precompiler_url` - the download URL template. Defaults to none.
+      Required when `make_precompiler` is set.
+
+    * `:make_precompiler_filename` - the filename of the compiled artefact
+      without its extension. Defaults to the app name.
+
+    * `:make_precompiler_downloader` - a module implementing the `ElixirMake.Downloader`
+      behaviour. You can use this to customize how the precompiled artefacts
+      are downloaded, for example, to add HTTP authentication or to download
+      from an SFTP server. The default implementation uses `:httpc`.
+
+    * `:make_force_build` - if build should be forced even if precompiled artefacts
+      are available. Defaults to true if the app has a `-dev` version flag.
+
+  See [the Precompilation guide](PRECOMPILATION_GUIDE.md) for more information.
+
+  ## Default environment variables
+
+  There are also several default environment variables set:
+
+    * `MIX_TARGET`
+    * `MIX_ENV`
+    * `MIX_BUILD_PATH` - same as `Mix.Project.build_path/0`
+    * `MIX_APP_PATH` - same as `Mix.Project.app_path/0`
+    * `MIX_COMPILE_PATH` - same as `Mix.Project.compile_path/0`
+    * `MIX_CONSOLIDATION_PATH` - same as `Mix.Project.consolidation_path/0`
+    * `MIX_DEPS_PATH` - same as `Mix.Project.deps_path/0`
+    * `MIX_MANIFEST_PATH` - same as `Mix.Project.manifest_path/0`
+    * `ERL_EI_LIBDIR`
+    * `ERL_EI_INCLUDE_DIR`
+    * `ERTS_INCLUDE_DIR`
+    * `ERL_INTERFACE_LIB_DIR`
+    * `ERL_INTERFACE_INCLUDE_DIR`
+
+  These may also be overwritten with the `make_env` option.
+
+  ## Compilation artifacts and working with priv directories
+
+  Generally speaking, compilation artifacts are written to the `priv`
+  directory, as that the only directory, besides `ebin`, which are
+  available to Erlang/OTP applications.
+
+  However, note that Mix projects supports the `:build_embedded`
+  configuration, which controls if assets in the `_build` directory
+  are symlinked (when `false`, the default) or copied (`true`).
+  In order to support both options for `:build_embedded`, it is
+  important to follow the given guidelines:
+
+    * The "priv" directory must not exist in the source code
+    * The Makefile should copy any artifact to `$MIX_APP_PATH/priv`
+      or, even better, to `$MIX_APP_PATH/priv/$MIX_TARGET`
+    * If there are static assets, the Makefile should copy them over
+      from a directory at the project root (not named "priv")
