+_🇬🇧 version_
+
+Python program to generate a collection of geotagged images from a video and a GPS track.
+
+Designed for ease contribution to street-level imagery projects like Mapillary or Panoramax.
+
+## Quick start
+
+Nothing simpler : collect your video, your GPS track, execute Python script and follow the guide !
+
+In detail, the program is built around a TUI or _Textual User Interface_, permitting to launch video process easily with
+step-by-step parameters input.
+
+Input is guided by textual help indicating attempted values.
+
+Before script starting, you need to have :
+* a video file with exact timestamp (start) in local time or UTC
+* a clean GPS tack file covering video duration
+* a working directory.

+
+_version 🇫🇷_
+
+Programme Python permettant de générer un ensemble d'images géotaguées depuis une vidéo et une trace GPS.
+
+Conçu pour faciliter la contribution à des projets de photo-cartographie de rue tels que Mapillary ou Panoramax.
+
+## Démarrage rapide
+
+Rien de plus simple : rassemblez votre vidéo, votre trace GPS, lancez le script Python et suivez le guide !
+
+En détail, le programme est entièrement construit autour d'une TUI ou _Textual User Interface_, qui permet de lancer
+facilement le traitement de la vidéo par la saisie pas-à-pas des paramètres.
+
+La saisie est guidée par une aide textuelle indiquant les valeurs attendues.
+
+Avant de lancer le script, vous avez besoin d'avoir :
+* un fichier vidéo avec son horodatage exact (début) en temps local ou UTC 
+* un fichier de trace GPS propre couvrant la durée de la vidéo
+* un dossier de travail.
+
+## Documentation
+
+_A venir._
+
+## Fonctionnalités
+
+Le programme permet d'exécuter en un seul traitement les tâches suivantes :
+* le séquençage de la vidéo selon un intervalle de temps
+* l'horodatage incrémental de la séquence d'image
+* l'export des images au format JPEG
+* le géotaguage des images exportées à partir de la trace GPS.
+
+Il inclut également :
+* le support des vidéos timelapse
+* le redimensionnement des images à une résolution inférieure à la vidéo d'origine tout en conservant le ratio
+* l'ajout de métadonnées avec les tags EXIF `artist`, `make`, `model` et `copyright` (cf. [documentation ExifTool](https://exiftool.org/TagNames/EXIF.html))
+* l'horodatage à la précision de la milliseconde
+* le support du temps local décalé par rapport à UTC.
+* l'ajout d'un décalage temporel pour mieux corréler la vidéo et la trace GPS.
+
+Lors de l'export, un sous-dossier nommé selon la vidéo est créé automatiquement dans le répertoire de sortie.
+
+### Comparaison v1 / v2

+## Versions
+
+Voir [_Releases_](https://git.luc-geo.fr/lumathieu/video2geoframes.py/releases).
+
+## Installation
+
+Pour installer le programme, il suffit de cloner le dépôt Git, d'installer les dépendances logicielles et de construire
+l'environnement Python. Il est recommandé d'utiliser un environnement virtuel (venv).
+
+### Python
+
+L'ensemble du projet est développé et testé avec **Python 3.11** (Windows x86-64).
+
+### Dépendances
+
+Le script principal utilise les librairies Python suivantes (voir aussi `requirements.txt`) :
+- `numpy`
+- `opencv-python`
+- `piexif`
+- `tomlkit`
+- `tqdm`.
+
+Il utilise également le programme [`ExifTool`](https://exiftool.org/) pour le géotaguage des images.
+Appelée par une commande système, cette dépendance est prévue pour être supprimée dans les versions futures.
+
+## Compatibilité
+
+Le code est conçu pour être indépendant de la plateforme.
+
+Les plateformes officiellement supportées sont Windows et Linux (partiellement testé sous Debian / Ubuntu).
+
+## Contribution
+
+_A venir._
+
+Si vous intéressé pour contribuer au projet, vous pouvez envoyer un mail à campanu@luc-geo.fr.
+
+## Licence
+
+Ce dépôt, à l'exception des dépendances, est sous licence **GNU AGPL v3**.
