+# Contributing Packages To conda-forge Using Grayskull
+
+When contributing packages to conda-forge, Grayskull can make your life
+much easier. Grayskull generates recipes for Python packages hosted on
+PyPI.
+
+<!--truncate-->
+
+As the
+[introduction](https://github.com/conda-incubator/grayskull#introduction)
+for Grayskull reads; "The main goal of this project is to generate
+concise recipes for conda-forge." In this tutorial we learn how to
+contribute a Python package to the conda-forge channel using Grayskull
+to generate the recipe.
+
+Let us get started.
+
+1.  Install `grayskull` using `conda` through the `conda-forge` channel:
+    
+    ```
+    $ conda install -c conda-forge grayskull
+    ```
+
+2.  Fork and clone the conda-forge [staged-recipes
+    repository](https://github.com/conda-forge/staged-recipes) from
+    GitHub.
+
+3.  Checkout a new branch from the `master branch`.
+
+4.  Through CLI, cd inside the 'staged-recipes/recipes' directory.
+
+5.  Call `grayskull` and pass the `pypi` repository, followed by the
+    name of the package you want to contribute to conda-forge. For
+    example: `grayskull pypi abc`
+
+    Or you could use `grayskull pypi abc --strict-conda-forge` to remove
+    some selectors which are not necessary for conda-forge and adapt
+    recipes to fit better in the conda-forge ecosystem.
+
+    Grayskull will create a folder with the same name as the package (in
+    this case: 'abc') in the 'recipes' folder of the 'staged-recipes'
+    directory. This folder will contain the `meta.yaml` file and also
+    the license file if the package includes a license in the PyPI
+    distribution.
+
+6.  Go through the generated `meta.yaml` file. For simpler packages, the
+    generated recipes are nearly perfect, but for some packages you
+    might need to make certain tweaks.
+
+7.  Commit and push the changes. `git add recipe/abc/meta.yaml`
+    `git commit -m "add a commit message"` `git push`
+
+8.  Create a PR.
+
+9.  Once the CI is passing, post a comment saying:
+    `This is ready for review` `@conda-forge-admin, please ping team`
+
+Once the PR gets merged, your package will be available on the
+conda-forge channel. Tada! It's that easy.
