+Bridge is a tool to connect your favourite editor and interpreter (or
+similar) for maximum profit.
+
+
+## usage by example
+
+    # start your favourite interpreter, e.g. bc, in a new session
+    bridge create my_fancy_interpreter bc
+
+    # attach a terminal to the session
+    bridge attach my_fancy_interpreter
+
+    # fire up your favourite editor (in another terminal)
+    vim
+    # press <F12> to connect to the session
+    # press return
+    # write interpreter stuff, e.g. 42^23
+    # mark that stuff
+    # press return
+
+    # paste some stuff into the session
+    bridge paste my_fancy_interpreter '1 + 2 + 4^M'
+    # (note that ^M is carriage return obtained by pressing ^V^M AKA C-V C-M)
+
+    # or use bridge as a sink in your pipeline
+    echo 2^20 | bridge paste my_fancy_interpreter
+
+    # you can use tab-completion everywhere (if installed)
+
+
+## install bridge (bourne) shell integration
+
+Hint #1: reboot your system or similar for this to take full effect
+Hint #2: you could also use ~/.profile or similar
+
+    echo 'PATH="${PATH+$PATH:}//bridge/bin"' >> /etc/profile
+
+
+## install bridge Vim integration
+
+Hint: your vim-setup probably differs
+
+    ln -s //bridge/share/vim/plugin/bridge.vim ~/.vim/plugin/
+
+
+## install bridge bash completion
+
+Hint #1: reboot your system or similar for this to take full effect
+Hint #2: this could differ on your system, of course
+Hint #3: you could also use ~/.profile or similar
+
+    ln -s //bridge/etc/bash_completion.d/bridge /etc/bash_completion.d/
+
+
+## install bridge into some usr-like hierarchy [advanced]
+
+    tar -C //bridge -c . |
