+Spell checking
+==============
+
+Ultimately, some auto spell checking for relevant files (and even git commit
+messages) would be awesome, but for now, we'll settle with manual install and
+setup.
+
+Install
+-------
+
+apt update
+apt install aspell aspell-en
+
+Usage - non-interactive
+-----------------------
+
+To get a list of words that the spellchecker doesn't recognise, first cd to the
+appliance build code directory, then::
+
+   export COMMON=$FAB_PATH/common
+   cat changelog | aspell list -a \
+                     --encoding=utf-8 \
+                     --personal=$PWD/spelling/.dic \
+                     --add-extra-dicts=$PWD/spelling/dic \
+                     --add-extra-dicts=$COMMON/spelling/common.dic \
+                     --add-extra-dicts=$COMMON/spelling/common_changelog.dic \
+                     > MIS_SPELLED.changelog
+
+   export COMMON=$FAB_PATH/common
+   cat README.rst | aspell list -a \
+                     --encoding=utf-8 \
+                     --personal=$PWD/spelling/.dic \
+                     --add-extra-dicts=$PWD/spelling/dic \
+                     --add-extra-dicts=$COMMON/spelling/common.dic \
+                     --add-extra-dicts=$COMMON/spelling/common_readme.dic \
+                     > MIS_SPELLED.readme
+
+Usage - interactive
+-------------------
+
+It is suggested that you run the above and add any new words (that are spelled
+right) to the spelling/dic (or one of the common dic files). Once you are ready
+to interactively run through this, you can do it like this::
+
+   export COMMON=$FAB_PATH/common
+   aspell -c changelog \
+         --dont-backup \
+         --encoding=utf-8 \
+         --personal=$PWD/spelling/.dic \
+         --add-extra-dicts=$PWD/spelling/dic \
+         --add-extra-dicts=$COMMON/spelling/common.dic \
+         --add-extra-dicts=$COMMON/spelling/common_changelog.dic
+
+   export COMMON=$FAB_PATH/common
+   aspell -c README.rst \
+         --dont-backup \
+         --encoding=utf-8 \
+         --personal=$PWD/spelling/.dic \
+         --add-extra-dicts=$PWD/spelling/dic \
+         --add-extra-dicts=$COMMON/spelling/common.dic \
+         --add-extra-dicts=$COMMON/spelling/common_readme.dic
+
+sort -f | uniq
