+Nazeka is a rikai replacement.
+
+*(Nazeka is not ready for general use yet; it does not yet have all the necessary behaviors that rikai variants have.**
+
+This is my first nontrivial javascript work and the code is probably terrible.
+
+# Options
+
+Nazeka has added many options since it was first created, and they're documented within the options page. The following is an example of what options it has:
+
+- Enabled: whether to search pages for text
+- Compact: definitions on same line or with linebreaks
+- Show original text: shows the string of text that nazeka used to look up a set of definitions
+- Super border: add an additional level to the double border
+- Fixed width: always use maximum width width, don't shrink to small contents
+- Position as though fixed width: when rejecting the popup from the right side of the window, act as though it has the maximum width, even if it doesn't
+- Search length: maximum length to search for words
+- Matching mode: what kinds, of alternative lookups to display
+- Strict matching for alternative matches: if true, alternative lookups of hiragana strings will not produce definitions that are not at least usually kana
+- Lookup popup scale: zoom factor for entire popup
+- Lookup popup width: maximum width for the lookup
+- Lookup throttle: minimum milliseconds between the start of lookups
+- Colors: the colors of the popup
+- Font override: font override for the whole popup, max priority but will fall back to default fonts for characters not in the font override
+- Font override (highlighted text only): for the main spelling of a definition
+
+Nazeka has added more options since this was written.
+
+# Building
+
+Build process requires python and lxml, or an existing copy of the extension to rip JMdict#.json from.
+
+- Copy the appropriate manifest.json from etc/ (either etc/firefox/manifest.json or etc/chrome/manifest.json) into the root of the repository
+- Download JMdict.gz from http://www.edrdg.org/jmdict/edict_doc.html
+- Convert it to json with etc/process.py
+- Move the output to under dict/ so that [...]/dict/JMdict1.json and others exist in that location relative to [...]/manifest.json
+- Make sure every .json file is listed as available to the extension in manifest.json - if jmdict added a lot of words, there might be more than 11 files now
+- Package as an extension for your browser of choice, or load it as a temporary/indev extension using your browser's development tools
