 This is a main program to simulate YM `SU(2)` and `SU(3)`
 theories. The main porpose is to compare with the existing literature
 and validate the code.
+
+## Installation, analysis and storing results
+
+### Installation
+
+1. clone the repo: `git clone https://gitlab.ift.uam-csic.es/alberto/test_latticegpu.jl.git`
+2. Start julia and `instantiate` the project:
+```julia
+julia> import Pkg
+julia> Pkg.instantiate("/path/to/test_latticegpu.jl")
+julia> using CUDA
+julia> A = randn(1000)
+julia> Ac = CuArray(1000)
+```
+	this should install all dependencies and dowload the necessary
+	`CUDA` packages. The `Manifest.toml` file guarantees that all runs
+	are performed with the same versions of all packages,
+	independently on the system where this runs.
+
+### Running simulations 
+
+1. To run a simulation use:
+```bash
+[user@cluster]$ julia --project=/path/to/test_latticegpu.jl /path/to/test_latticegpu.jl/src/ym.jl -i <input file>
+```
+2. An example input file is available in `examples/ym.in`
+
+### Results: analysis and storage
+
+Data from testing runs should be collected in the `data` folder. Each
+run should be in its own directory. The input file should be included
+in this git repository. The `log.gz` and `bdio` files should be stored
+in ciclope using `dvc`.
+
+## TODO list
+
+### Screwing with `LatticeGPU`
+
+This section is devoted to repeating small runs with different
+parameters (i.e. `block sizes`, strange `geometries` to make sure that
+everything works as expected).
+
+### Reproducing numbers in the literature

+#### Flow measurements in arXiv1006.4518
