-```@index

+
+
+## Installation
+
+`DataViewer` is not registered (yet), so you need to provide its full URL to the Julia package manager.
+
+```julia-repl
+julia> ] # enter Pkg mode
+pkg> add https://github.com/triscale-innov/DataViewer.jl.git
+```
+
+Since `DataViewer` requires a lot of heavy dependencies, it is not advised to
+add it to the default environment. One possibility would be to create a
+dedicated named environment:
+
+```julia-repl
+julia> ] # enter Pkg mode
+(@v1.9) pkg> activate @dataviewer
+(@dataviewer) pkg> add https://github.com/triscale-innov/DataViewer.jl.git
+```
+
+## Use as a Julia package
+
+`DataViewer` can be used as a regular package from inside a Julia REPL. Whenever
+there is some data structure that you want to explore, call the [`view`](@ref) function:
+```julia-repl
+julia> using JLD2
+
+julia> data = JLD2.load("sample.jld2");
+
+julia> using DataViewer
+[ Info: Precompiling DataViewer [69fa7e04-3a55-42d6-bb08-3ca48704fbef]
+[ Info: Precompiling JSON_Ext [056fc32c-03f3-5092-ad64-0a1590c5cd8d]
+[ Info: Precompiling JLD2_Ext [ab4143e6-3402-5971-8428-17ae5f4067b4]
+
+julia> DataViewer.view(data)
+```
+
+It is also possible to directly call [`view`](@ref) on a file name:
+```julia-repl
+julia> using HDF5
+[ Info: Precompiling HDF5_Ext [c89765bd-c6f5-5c69-b5b2-135d132d13bc]
+
+julia> DataViewer.view("sample.h5")
+```
+
+!!! note
+
+    In this case, you'll need to first load the appropriate package for the file
+    format you want to read: `HDF5`, `JLD2` or `JSON`.
+
+## Use as a standalone application
+
+After having installed the `DataViewer` package, you can ask it to
+[`install`](@ref) a standalone application, callable from the command-line:
+
+```julia-repl
+julia> using DataViewer
+
+julia> DataViewer.install()
+```
+
+By default, a launcher named `dataviewer` will be placed in the `~/.julia/bin`
+directory, which you should add to your `PATH` environment variable. Afterwards,
+you can run this new command from a shell.
+
+!!! note
+
+    Windows users may want to run something like:
+    
+    ```
+    julia> DataViewer.install(destdir = joinpath(homedir(), "Desktop"))
+    ```
+    
+    in order to put the launcher on their desktop.
+
+Without argument, a file picker window will pop up to ask for a file to open:
+```shell
+$ dataviewer
+```
+
+With one argument, the given file will be viewed:
+```shell
+$ dataviewer sample.hdf5
 ```
 
-```@autodocs
-Modules = [DataViewer]
+A second argument allows specifying the file type if the extension is not enough
+to guess it. This optional argument may be either the name of the relevant Julia
+package (*e.g* `JSON`) or a file extension associated to the file format (*e.g* `.json`):
+```shell
+$ dataviewer sample JSON

+Open a viewer window for the data contained in file `fname`.

+The extension of `fname` is normally used to determine how to read it. But the
