+This is useful for example if you get [Board not found error](https://github.com/wekan/wekan/issues/1430)
+
+## 1) Download Wekan grain
+
+Use Sandstorm arrow down button to download Wekan grain in .zip file.
+
+## 2) Unzip downloaded file
+
+## 3) Install latest Wekan, or only MongoDB 3.2.20 or newer locally
+
+[Install from releases page](https://github.com/wekan/wekan/releases)
+
+## 4) Stop Wekan and MongoDB
+
+## 5) Copy database files from unzipped Wekan grain to MongoDB
+
+In .zip file database files are in directory `data/wiredTigerDb/`
+
+In Wekan Snap, database files are in directory `/var/snap/wekan/common` - if you have other data there, rename common directory to other name first.

+
+## 6) Change database file permissions to root user
+
+In Snap:
+```
+sudo chown root:root /var/snap/wekan/common -R
+```
+
+## 7) Start MongoDB
+
+In Snap:
+```
+sudo snap start wekan.mongodb
+```
+
+## 8) Or, if you are brave, also start standalone wekan
+
+Try does Standalone Wekan work with that database
+```
+sudo snap start wekan.mongodb
+sudo snap start wekan.wekan
+```
+or both wekan and database at once
+```
+sudo snap start wekan
+```
+
+## 9) To see MongoDB data, install Robo3T GUI
+
+https://robomongo.org
+
+Wekan Snap: Connect it to address `localhost:27019`
+
+Wekan Docker: If you have MongoDB exposed to outside Docker, Connect with Robo3T to address `localhost:27017`. Otherwise you first need to copy files from wekan-db Docker container to outside of Docker container, and restore files to local separately installed MongoDB database v3.2.20 or newer
