 # IDAKLU solver
 
-Standalone repository for the IDAKLU solver used in PyBaMM
+Standalone repository for the C/C++ solvers used in PyBaMM
 
 ## Installation
 
 ```bash
 pip install pybammsolvers 
 ```
+
+## Solvers
+
+The following solvers are available:
+- PyBaMM's IDAKLU solver
+
+## Local builds
+
+For testing new solvers and unsupported architectures, local builds are possible.
+
+### Nox
+
+Nox can be used to do a quick build:
+```bash
+pip install nox
+nox
+```
+This will setup an environment and attempt to build the library.
+
+### MacOS
+
+Mac dependencies can be installed using brew
+```bash
+brew install libomp
+brew reinstall gcc
+python install_KLU_Sundials.py
+pip install .
+```
+
+### Linux
+
+Linux installs may vary based on the distribution, however, the basic build can
+be performed with the following commands:
+```bash
+sudo apt-get libopenblas-dev gcc gfortran make g++ build-essential
+pip install cmake casadi setuptools wheel
+python install_KLU_Sundials.py
+pip install .
+```
