+# How to Install a Discourse Plugin for Events
+
+## 1. Create a new discourse installation for testing
+
+1. Initialize a new discourse site:
+
+   ```bash
+   ds init discourse @forum1.flossk.org
+   cd /var/ds/forum1.flossk.org/
+   ```
+
+2. Copy `settings.sh` from the original site, but change `DOMAIN` to the new one (`forum1.flossk.org`):
+
+   ```bash
+   cp ../forum.flossk.org/settings.sh .
+   vim settings.sh
+   ```
+
+3. Make the container:
+
+   ```bash
+   cd /var/ds/forum1.flossk.org
+   ds make
+   ```
+
+   (It may take a few minutes.)
+
+## 2. Take a backup from the original site and restore it on the test site
+
+```bash
+cd /var/ds/forum.flossk.org/
+ds backup
+ls backup/
+
+mkdir -p ../forum1.flossk.org/backup/
+cp backup/flossk-2020-07-10-171654-v20200710013237.tar.gz \
+   ../forum1.flossk.org/backup/
+cd ../forum1.flossk.org/
+ds restore backup/flossk-2020-07-10-171654-v20200710013237.tar.gz
+```
+
+**Note:** For some reason it does not work for the first time. Try it a second time:
+```bash
+ds restore backup/flossk-2020-07-10-171654-v20200710013237.tar.gz
+```
+
+Now we can open the test site https://forum1.flossk.org and login as admin.
