+
+Python interface to the [QDLDL](https://github.com/oxfordcontrol/qdldl/)
+free LDL factorization routine for quasi-definite linear systems: `Ax =
+b`.
+
+## Installation
+
+This package can be directly installed via pip,
+
+```
+pip install qdldl
+```
+
+## Usage
+
+Initialize the factorization with
+
+```
+import qdldl
+F = qdldl.Solver(A)
+```
+
+where `A` must be a square quasi-definite matrix in [scipy sparse CSC
+format](https://docs.scipy.org/doc/scipy/reference/generated/scipy.sparse.csc_matrix.html).
+
+The algorithm internally converts the matrix into upper triangular format. If `A` is already upper-triangular, you can specify it with the argument `upper=True` to the `qdldl.Solver` constructor.
+
+To solve the linear system for a right-hand side `b`, just write
+
+```
+x = F.solve(b)
+```
+
+To update the factorization without changing the sparsity pattern of `A` you can run
+
+```
+F.update(A_new)
+```
+
+where `A_new` is a sparse matrix in CSR format with the same sparsity pattern as `A`.
+
+The algorithm internally converts `A_new` into upper triangular format. If `A_new` is already upper-triangular, you can specify it with the argument `upper=True` to the `F.update` function.
