+# An Offline Console Russian Dictionary (based on openrussian.org)
+
+* Works offline (without internet access) and is very fast.
+  This really pays off if you browse Russian words a lot.
+* It integrates well into the console environment - browse dictionary
+  entries like man pages.
+  Internally, Troff code is generated which makes further processing of generated
+  pages ~~very easy~~ possible.
+* Puts very low requirements on the runtime environment:
+  a black and white terminal display is sufficient.
+* Bash auto completions supported.
+  Most of this is handled by the script's `-C` argument, so it
+  is trivial to add support for other shells.
+  Contributions are welcome!
+* Search terms can be: base forms (infinitives, nominative singular nouns...),
+  inflections (all cases, conjugations, short forms, imperatives...) and
+  translations.
+* Search terms are [glob patterns](https://en.wikipedia.org/wiki/Glob_(programming)),
+  which is very useful for looking up words with uncertain spelling or finding
+  related words.
+
+Possible future features:
+
+* Bilingual modes (German and English translations on the same generated page)
+  to increase the amount of information if you happen to speak both of these languages.
+* Better internationalization when generating German pages (`-Lde`).
+* Lookups via popular ASCII-cyrillic transliterations - would be useful without
+  a Russian/cyrillic keyboard layout.
+* Be tolerant to typing mistakes.
+* Accented characters are still broken in nroff tables
+  (see https://lists.gnu.org/archive/html/groff/2018-08/msg00000.html).
+
+## Installation
+
+Build-time dependencies:
+
+    sudo apt-get install make pkg-config lua5.2 bash-completion wget unzip gawk sqlite3
+
+Run-time dependencies:
+
+    sudo apt-get install lua5.2 lua-sql-sqlite3 man-db bash-completion
+
+Furthermore, you will need the [luautf8 library](https://github.com/starwing/luautf8).
+Using luarocks, it may be installed as follows:
+
+    sudo luarocks-5.2 install luautf8
+
+Building is straight forward:
+
+    make
+    sudo make install
