-## Contributing
-
-Standard matrix decomposion routines of Eigen such as the SVD and QR decompositions can be readily added to **EigenPy** following the example of the Cholesky decomposition that is already implemented. Feel free to open a PR if you wrap them for your use case.
-
-## Build/install from source with Pixi
-
-To build **EigenPy** from source the easiest way is to use [Pixi](https://pixi.sh/latest/#installation).
-
-[Pixi](https://pixi.sh/latest/) is a cross-platform package management tool for developers that
-will install all required dependencies in `.pixi` directory.
-It's used by our CI agent so you have the guarantee to get the right dependencies.
-
-Run the following command to install dependencies, configure, build and test the project:
-
-```bash
-pixi run test
-```
-
-The project will be built in the `build` directory.
-You can run `pixi shell` and build the project with `cmake` and `ninja` manually.
-
-## Release with Pixi
-
-To create a release with Pixi run the following commands on the **devel** branch:
-
-```bash
-EIGENPY_VERSION=X.Y.Z pixi run release_new_version
-git push origin
-git push origin vX.Y.Z
-git push origin devel:master
-```
-
-Where `X.Y.Z` is the new version.
-Be careful to follow the [Semantic Versioning](https://semver.org/spec/v2.0.0.html) rules.
+## Build
 
-You will find the following assets to upload to GitHub:
-- `./build_new_version/eigenpy-X.Y.Z.tar.gz`
-- `./build_new_version/eigenpy-X.Y.Z.tar.gz.sig`
+Build instruction can be found [here](./development/build.md)
