+appvm
+=====
+
+*appvm* is the thin easy-to-use hypervisor-based sandboxing software.
+
+*appvm* was created for the purpose of decreasing complexity of using
+graphical software inside virtual machines, at the same time
+maintaining reasonable security and keep *appvm* itself simple and
+portable.
+
+While I'm trying to keep that documentation up-to-date, there may be
+some missing information. Use ``appvm --help-long`` for checking all
+features.
+
+If you found anything missed here, please make a pull request or send
+patches to patch@dumpstack.io.
+
+If you need personal support, your company is interested in the
+project or you just want to share some thoughts -- feel free to create
+a new issue or write to root@dumpstack.io.
