+# Ala-hub
+
+## Setup
+
+Create data directory at `/data/ala-hub` and populate as below (it is easiest to symlink the config files to the ones in this repo):
+```
+mats@xps-13:/data/ala-hub$ tree
+.
+└── config
+    ├── ala-hub-config.properties -> /home/mats/src/biodiversitydata-se/ala-hub/sbdi/data/config/ala-hub-config.properties
+    ├── charts.json -> /home/mats/src/biodiversitydata-se/ala-hub/sbdi/data/config/charts.json
+    └── grouped_facets_default.json -> /home/mats/src/biodiversitydata-se/ala-hub/sbdi/data/config/grouped_facets_default.json
+```
+
+## Usage
+
+Run locally:
+```
+make run
+```
+
+Build and run in Docker (using Tomcat):
+```
+make run-docker
+```
+
+Make a release. This will create a new tag and push it. A new Docker container will be built on Github.
+```
+mats@xps-13:~/src/biodiversitydata-se/ala-hub (master *)$ make release
+
+Current version: 1.0.1. Enter the new version (or press Enter for 1.0.2): 
+Updating to version 1.0.2
+Tag 1.0.2 created and pushed.
+```
