 ## How-Tos
 
+### Create a new page
+
+By using `hugo new` you can create a new page with the correct frontmatter for that kind of page:
+
+```bash
+hugo new --kind benchmark docs/benchmarks/elliptic/groundwater-flow-dirichlet.md
+```
+
+- `--kind` is one the `archetypes/*`
+- path is relative to `content/` and determines the URL of the page
+
 ### Images
 
 Use shortcode `img`:

+## Equations
+
+## Input files
+
+The main project file is `[TODO]`. It describes the processes to be solved and the related process variables together with their initial and boundary conditions. It also references the mesh and geometrical objects defined on the mesh.
+
+As of now a small portion of possible inputs is implemented; one can change:
+ - the mesh file
+ - the geometry file
+ - introduce more/different Dirichlet boundary conditions (different geometry or values)
+
+The geometries used to specify the boundary conditions are given in the `[TODO]` file.
+
+The input mesh `[TODO]` is stored in the VTK file format and can be directly visualized in Paraview for example.
+
+## Running simulation
+
+To start the simulation (after successful compilation) run:
+```bash
+$ ogs [TODO]
+```
+
