+### Using Sphinx?
+
+#### Having trouble writing cross-references?
+
+`sphobjinv` (short for '**sph**inx **obj**ects.**inv**') can help!
+
+The syntax required for a functional Sphinx cross-reference is highly
+non-obvious in many cases. Sometimes Sphinx can guess correctly what
+you mean, but it's pretty hit-or-miss.  The best approach is to provide
+Sphinx with a completely specified cross-reference, and that's where
+`sphobjinv` comes in.
+
+After a `pip install sphobjinv` (or `pipx install sphobjinv`), find the
+documentation set you want to cross-reference into, and pass it to
+`sphobjinv suggest`.
+
+For internal cross-references, locate `objects.inv` within `build/html`:
+
+```none
+$ sphobjinv suggest doc/build/html/objects.inv as_rst -st 58
+
+------------------------------------------------
+
+Cannot infer intersphinx_mapping from a local objects.inv.
+
+------------------------------------------------
+
+Project: sphobjinv
+Version: 2.3
+
+220 objects in inventory.
+
+------------------------------------------------
+
+11 results found at/above current threshold of 58.
+
+
+  Name                                                Score
+---------------------------------------------------  -------
+:py:property:`sphobjinv.data.SuperDataObj.as_rst`      60
+:py:class:`sphobjinv.cli.parser.PrsConst`              59
+:py:class:`sphobjinv.data.DataFields`                  59
+:py:class:`sphobjinv.data.DataObjBytes`                59
+:py:class:`sphobjinv.data.DataObjStr`                  59
+:py:class:`sphobjinv.data.SuperDataObj`                59
+:py:class:`sphobjinv.enum.HeaderFields`                59
+:py:class:`sphobjinv.enum.SourceTypes`                 59
+:py:function:`sphobjinv.fileops.writebytes`            59
+:py:function:`sphobjinv.fileops.writejson`             59
+:py:class:`sphobjinv.inventory.Inventory`              59
+```
+
+The `-s` argument in the above shell command indicates to print the
+`fuzzywuzzy` match score along with each search result, and `-t 50`
+changes the reporting threshold for the match score.
+
+For external references, find the API documentation wherever it lives on
+the web, and pass `sphobjinv suggest` a URL from within the documentation set
+with the `--url/-u` flag. For example, say I need to know how to
+cross-reference the `linspace` function from numpy (see
+[here][numpy linspace]):
+
+```none
+$ sphobjinv suggest https://numpy.org/doc/1.23/reference/index.html linspace -su
+
+Attempting https://numpy.org/doc/1.23/reference/index.html ...
+  ... no recognized inventory.
+Attempting "https://numpy.org/doc/1.23/reference/index.html/objects.inv" ...
+  ... HTTP error: 404 Not Found.
+Attempting "https://numpy.org/doc/1.23/reference/objects.inv" ...
+  ... HTTP error: 404 Not Found.
+Attempting "https://numpy.org/doc/1.23/objects.inv" ...
+  ... inventory found.

+
+  Name                                                           Score
+--------------------------------------------------------------  -------
+:py:function:`numpy.linspace`                                     90
+:py:method:`numpy.polynomial.chebyshev.Chebyshev.linspace`        90

+:std:doc:`reference/generated/numpy.linspace`                     90
+```
+
+**NOTE** that the results from `sphobjinv suggest` are printed using the
+longer *block directives*, whereas cross-references must be composed using the
+*inline directives*. Thus, the above `linspace()` function must be
+cross-referenced as ``` :func:`numpy.linspace` ``` , **not**
+``` :function:`numpy.linspace` ```.
+
+**Need to edit an inventory after it's created, or compose one from scratch?**
+
+`sphobjinv` can help with that, too.
+
+`objects.inv` files can be decompressed to plaintext at the commandline:
+
+```none
+$ sphobjinv convert plain -o doc/build/html/objects.inv doc/scratch/
+Conversion completed.
+'...objects.inv' converted to '...objects.txt' (plain).
+```
+
+JSON output is supported (`sphobjinv convert json ...`), and
+inventories can be re-compressed to the
+partially-zlib-compressed form that `intersphinx` reads
+(`sphobjinv convert zlib ...`).
+
+Alternatively, `sphobjinv` exposes an API to enable automation of
+inventory creation/modification:
+
+```python
+>>> import sphobjinv as soi
+>>> inv = soi.Inventory('doc/build/html/objects.inv')
+>>> print(inv)
+<Inventory (fname_zlib): sphobjinv v2.3, 220 objects>
+>>> inv.project
+'sphobjinv'
+>>> inv.version
+'2.3'
+>>> inv.objects[0]
+DataObjStr(name='sphobjinv.cli.convert', domain='py', role='module', priority='0', uri='cli/implementation/convert.html#module-$', dispname='-')
+```
+
+The API also enables straightforward re-export of an inventory, for subsequent
+use with `intersphinx` cross-references. See [the docs][soi docs inv export] for
+more details.
