+mp-docs-shared
+==============
+
+### Files shared by multiple [MATPOWER][1] documentation projects.
+
+[MATPOWER][1] documentation projects, based on [Sphinx][2], expect to find
+an `mp-docs-shared` directory with the contents of this repo in their
+`source` directory. The main [MATPOWER][1] project already includes it as
+a [`git subrepo`][3]. However, building the documentation for individual
+components separetely (e.g. MP-Test, MIPS, MP-Opt-Model, etc.) requires
+that `mp-docs-shared` be manually included in the `source` directory before
+building.
+```
+cd <project>/docs/sphinx/source
+git clone https://github.com/MATPOWER/mp-docs-shared.git
+```
+
+Each project typically also relies on the use of a symlink for the CSS file.
+```
+cd <project>/docs/sphinx/source/_static/css
+ln -s ../../mp-docs-shared/css/matpower.css matpower.css
+```
