+Ce document explique comment utiliser `pbmap/PBMap.pb` facilement, avec un demarrage rapide, des exemples et le detail de chaque procedure publique.
+
+## Demarrage rapide
+
+Objectif: afficher une carte, ajouter un marqueur et deplacer la vue.
+
+```purebasic

+

+  #Win
+  #Map

+
+Notes importantes:
+- Activez "Create ThreadSafe Executable" dans les options du compilateur.
+- Appelez `InitNetwork()` avant les telechargements HTTP.
+- Les tuiles sont telechargees automatiquement via HTTP/HTTPS.
+
+## Ce que PBMap permet de faire
+
+- Afficher une carte (tuiles OSM/HERE/GeoServer).
+- Gerer des marqueurs (ajout, selection, edition).
+- Gerer des traces GPX (chargement, affichage, suppression).
+- Changer la vue (zoom, angle, centrage).
+- Configurer le cache disque et memoire.
+- Ajouter des callbacks pour reagir aux mouvements et aux clics.
+- Utiliser un clustering de marqueurs pour une meilleure lisibilite.

+## Clustering des marqueurs (explication)
+
+Le clustering regroupe les marqueurs proches en un seul cercle.
+- `EnableClusters`: active ou non.
+- `ClusterPixelSize`: taille de la grille (en pixels).
+- `ClusterMinCount`: nombre minimum pour afficher un cluster.
+
+Double-clic sur un cluster: zoom sur le centre du cluster.
+
+## Astuces pratiques
+
+- Activez `Verbose` pour diagnostiquer les chargements de tuiles.
+- Utilisez `TileLifetime` pour gerer l'expiration du cache.
+- Si vous avez beaucoup de marqueurs, activez le clustering.
+- Pour des couches multiples, ajustez `SetLayerAlpha`.
+- Si l'interface devient lente, reduisez `MaxThreads` ou `MaxDownloadSlots`.
+
