+## Getting Started
+
+### build + install dependencies
+
+- [github/Rconybea/xo-pyutil](https://github.com/Rconybea/xo-pyutil)
+- [github/Rconybea/xo-printjson](https://github.com/Rconybea/xo-printjson)
+
+### build + install
+
+```
+$ cd xo-pyprintjson
+$ mkdir build
+$ cd build
+$ INSTALL_PREFIX=/usr/local  # or wherever you prefer, e.g. ~/local
+$ cmake \
+    -DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
+    -DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
+    -DCMAKE_INSTALL_PREFIX=${INSTALL_PREFIX} ..
+$ make
+$ make install
+```
+(also see .github/workflows/main.yml)
+
+## Examples
+
+```
+PYTHONPATH=~/local2/lib:$PYTHONPATH python
+>>> import xo_pyprintjson
+>>> dir(xo_pyprintjson)
+['PrintJson', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__']
+>>> dir(xo_pyprintjson.PrintJson)
+['__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'instance', 'print']
+>>>
+```
+
+## Development
+
+### build for unit test coverage
+```
+$ cd xo-pyprintjson
+$ mkdir build-ccov
+$ cd build-ccov
+$ cmake \
+    -DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
+    -DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
+    -DCODE_COVERAGE=ON \
+    -DCMAKE_BUILD_TYPE=Debug ..
+```
+
+### LSP (language server) support
+
+LSP looks for compile commands in the root of the source tree;
+while Cmake creates them in the root of its build directory.
+
+```
+$ cd xo-pyprintjson
+$ ln -s build/compile_commands.json  # supply compile commands to LSP
+```
+
+### display cmake variables
+
+- `-L` list variables
+- `-A` include 'advanced' variables
+- `-H` include help text
+
+```
+$ cd xo-pyprintjson/build
+$ cmake -LAH
+```
