Clean up documentation around beginner's guide.

- move `README` to `README.md` to take advantage of markdown features
- remove `setup.txt`, port the editor specific information to the wiki.
  Merge development information into `dev/doc/README.md`.
      Wiki merge link: https://github.com/coq/coq/wiki/DevelSetup.
- Add new links to files into `dev/README.md`.
- Remove stale `translate.txt`.

+# Beginner's guide to hacking Coq
+
+## Getting dependencies
+
+Assuming one is running Ubuntu (if not, replace `apt` with the package manager of choice)
+
+```
+$ sudo apt-get install make opam git
+
+# At the time of writing, <latest-ocaml-version> is 4.06.1.
+# The latest version number is available at: https://ocaml.org/releases/
+
+$ opam init --comp <latest-ocaml-version>
+
+# Then follow the advice displayed at the end as how to update your
+  ~/.bashrc and ~/.ocamlinit files.
+
+$ source ~/.bashrc
+$ opam install camlp5
+
+# needed if you want to build "coqide" target
+
+$ sudo apt-get install liblablgtksourceview2-ocaml-dev \
+  libgtk2.0-dev libgtksourceview2.0-dev
+$ opam install lablgtk
+```
+
+## Building `coqtop`
+The general workflow is to first setup a development environment with
+the correct `configure` settings, then hacking on Coq, make-ing, and testing.
+
+
+This document will use `$JOBS` to refer to the number of parallel jobs one
+is willing to have with `make`.
+
+
+```
+$ git clone git clone https://github.com/coq/coq.git
+$ cd coq
+$ ./configure -profile devel
+$ make -j $JOBS # Make once for `merlin`(autocompletion tool)
+
+<hack>
+
+$ make -j $JOBS states # builds just enough to run coqtop
+$ bin/coqtop -compile <test_file_name.v>
+<goto hack until stuff works>
+
+<run test-suite>
+```
+
+To learn how to run the test suite, you can read
+[`test-suite/README.md`](../../test-suite/README.md).
+
+## Coq functions of interest
+- `Coqtop.start`: This function is the main entry point of coqtop.
+- `Coqtop.parse_args `: This function is responsible for parsing command-line arguments.
+- `Coqloop.loop`: This function implements the read-eval-print loop.
+- `Vernacentries.interp`: This function is called to execute the Vernacular command user have typed.
+                       It dispatches the control to specific functions handling different Vernacular command.
+- `Vernacentries.vernac_check_may_eval`: This function handles the `Check ...` command.
+
+
+## Development environment + tooling
+- [`Merlin`](https://github.com/ocaml/merlin) for autocomplete.
+- [Wiki pages on tooling containing `emacs`, `vim`, and `git` information](https://github.com/coq/coq/wiki/DevelSetup)
+
+## A note about rlwrap
+
+When using `rlwrap coqtop` make sure the version of `rlwrap` is at least
+`0.42`, otherwise you will get
+
+```
+rlwrap: error: Couldn't read completions from /usr/share/rlwrap/completions/coqtop: No such file or directory
+```
+
+If this happens either update or use an alternate readline wrapper like `ledit`.
