+## Installation from source
 
 The code needs the quad precision pieces of the sleef library, which
 is not available on most systems by default, so we have to generate
 that first.  The below assumes one has the required pieces to build
 sleef (cmake and libmpfr-dev), and that one is in the package
 directory locally.

+git clone --branch 3.8 https://github.com/shibatch/sleef.git
 cd sleef
 cmake -S . -B build -DSLEEF_BUILD_QUAD:BOOL=ON -DSLEEF_BUILD_SHARED_LIBS:BOOL=ON -DCMAKE_POSITION_INDEPENDENT_CODE=ON

+Building the `numpy-quaddtype` package from locally installed sleef:
+```bash
 export SLEEF_DIR=$PWD/sleef/build
 export LIBRARY_PATH=$SLEEF_DIR/lib
 export C_INCLUDE_PATH=$SLEEF_DIR/include
 export CPLUS_INCLUDE_PATH=$SLEEF_DIR/include
-python3 -m venv temp
-source temp/bin/activate

+# Install the package
 pip install meson-python numpy pytest
 pip install -e . -v --no-build-isolation
 export LD_LIBRARY_PATH=$SLEEF_DIR/lib
 ```
 
-Here, we created an editable install on purpose, so one can just work
