[WIP] simplified installation manual

docs/install.md

-# Installation
 
-Detailed installation instructions, including how to install Python from scratch,
-are described in the [detailed installation manual](docs/install-manual-detailed.md).
 
+# Installation using Anaconda (Windows/Mac/Linux)
 
-If you know what you are doing, you can install as a package as follows:
+Install the necessary Python dependencies using the conda package manager:
 
 ```
-python setup.py install
+conda install setuptools_scm future h5py pytables pytest nose sphinx
+conda install scipy pandas matplotlib cython xlrd coverage xlwt openpyxl psutil
+conda install -c https://conda.anaconda.org/conda-forge pyscaffold pytest-cov
 ```
 
-Or in development mode, install from your working directory
+Now you can install ```wetb``` with ```pip```. However, we would like that
+conda keeps track of the dependencies, so we'll tell ```pip``` not to check them:
 
 ```
-pip install -e ./
+pip install wetb --upgrade --no-deps
 ```
 
-
-Or create a binary wheel distribution package with:
+# Updating ```wetb``` using Anaconda
 
 ```
-python setup.py bdist_wheel -d dist
+conda update --all
+pip install wetb --upgrade --no-deps
+
 ```

 This module is tested for Python 2 and 3 compatibility, and works on both
 Windows and Linux. Testing for Mac is on the way, but in theory it should work.
