now everything is happening inside vitrual environment, which is much
more safe and easier to use.

+Putnik is rough condensed cyrillic display font. It is primarily inspired by
+runic script, early cyrillic script and wooden pagan inscriptions.
 This font is non-professional, though.
 
-Putnik was made especially for [short-movie by Ilya Osenev](https://www.youtube.com/watch?v=VteH0cZsxPg) with the same name.

 Font is made with Inkscape and FontForge.
 
 ## Glyph set
 
-Currently there's not too much glyphs. There is cyrillic (all caps), digits and incomplete set of punctuation.

 ## Compilation
 
 ### Prerequisites
 
-You need python, pip and fontmake.
+All you need is python and pip and venv modules. If you are using Linux or MacOS,
+chanses are you already have all of this. If not, install them using your package
+manager.
 
-```terminal
-$ python -m pip install fontmake
+```console
+$ which python
+/usr/bin/python
+$ python -m pip --version
+pip XX.X.X from /usr/lib/python3.8/site-packages/pip (python 3.8)
 ```
 
 ### Building
 
 To build both otf and ttf versions, just run
 
-```terminal
+```console
 $ make
 ```
 
+This will create python virtual environment in directory `venv`, install fontmake
+package from requirements.txt and build the fonts to `fonts/` directory.
+
 If you want only ttf or otf, run 
 
-```terminal
+```console
 $ make otf
 ```
 
 or
 
-```terminal
+```console
 $ make ttf
 ```
 
 respectively.
 
+To make zip or tarball package, run `make release`.
+
