 Custom materials used in this map are available inside the materials folder. Do not forget to install them before attempting to compile it through Valve Hammer Editor.
 
-## Running this map on a server
+## Getting the map
 
-1. Install the map
-2. Generate the navigation meshes file.
+Build the map or download the [latest release](https://git.quent1.fr/quent1/de_abandoned_hospital/releases).
 
-## Generating the navigation meshes files
+## Building the map
 
-Open the server console and execute : 
+Open `de_abandoned_hospital.vmf` with Valve Hammer Editor (Counter Strike : Global Offensive SDK version). Press `F9` to compile, then select `Expert...` and choose the `Full compile -both -final (slow)` preset. Compilation will be way slower but it will ensure that the lightning of static props on the map are correctly rendered. 
+
+Once installed, do not forget to generate the navigation meshes file.
+
+## Generating the navigation meshes file
+
+Open CS:GO console and execute : 
 
 	map de_abandoned_hospital
 	sv_cheats 1
 	nav_generate
 	
-Wait a few minutes until the file is generated. The server may become unresponsive during that generation.
+Now that the standard mesh file is generated, we need to check for missing floors (upper floors and ladders). See this [Valve wiki page](https://developer.valvesoftware.com/wiki/Navigation_Meshes#Explicitly_marking_walkable_areas_.28i.e:_.22There.27s_no_mesh_upstairs.22.29) for more details.
+
+To do so, execute the following commands :
+
+	sv_cheats 1
+	nav_edit 1
+	
+To mark a floor as walkable, execute :
+
+	nav_mark_walkable
+	
+Once all floors are marked as walkable, rebuild the navigation meshes file :
+
+	nav_generate
+	
+If the meshes are correctly generated, add all ladders then save the file :
+
+	nav_build_ladder
+	nav_save
