+# Animal Management Installation Guide
+
+This guide installs the `animal_management` module in a reusable way for any HumHub instance.
+
+## 1. Requirements
+
+- HumHub `1.14+`
+- Module directory access on the target instance
+- Optional but recommended: `rescue_foundation` module
+
+## 2. Clone into HumHub Modules Directory
+
+The folder name must be exactly `animal_management`.
+
+```bash
+git clone https://gitea.kelinreij.duckdns.org/humhub-modules/animal-management.git \
+  /var/www/localhost/htdocs/protected/modules/animal_management
+```
+
+If the folder already exists:
+
+```bash
+cd /var/www/localhost/htdocs/protected/modules/animal_management
+git pull
+```
+
+## 3. Enable the Module
+
+In HumHub UI:
+
+1. Go to `Administration` -> `Modules`.
+2. Enable `Animal Management`.
+3. Enable it per space where needed.
+
+## 4. Run Migrations
+
+From the HumHub app host/container:
+
+```bash
+php /var/www/localhost/htdocs/protected/yii migrate/up \
+  --include-module-migrations=1 --interactive=0
+```
+
+## 5. Verify
+
+1. Open a space where the module is enabled.
+2. Confirm Animals views load.
+3. Confirm medical/progress/transfer flows render without errors.
+
+## Docker Example
+
+```bash
+docker exec humhub php /var/www/localhost/htdocs/protected/yii migrate/up \
+  --include-module-migrations=1 --interactive=0
+```
