+Originally inspired by https://github.com/jkarlosb/git-server-docker
+
+This container allows to run a minimal git server with a basic CLI to manage repositories.
+It supports multiple accounts.
+
+# Minimal configuration
+
+This container requires 3 volumes in order to correctly persist data :
+- `/srv/ssh` to persist generated server keys
+- `/srv/git` to store repositories
+- `/srv/accounts` to setup available accounts, with allowed public keys
+
+```
+docker run -v .../ssh:/srv/ssh -v .../git:/srv/git -v .../accounts:/srv/accounts \
+        --env EXTERNAL_PORT=20222 --env EXTERNAL_HOSTNAME=xxxx \
+        --name minimal-git-server -d -p 20222:22 ghcr.io/mcarbonne/minimal-git-server:latest
+```
+
+
+# /srv/accounts structure
+
+```
+user-A:12345
+  key_A.pub
+user-B:12346
+  key_B.pub
+shared:12347
+  key_A.pub
+  key_B.pub
+```
+
+For every account, create a folder `username:uid` in /srv/accounts.
+Put every public keys allowed to access this account in the created directory.
