+### While we're at it, add trees
+As a near-max zoom level thing only.
+https://www.openstreetmap.org/node/3192142615
+Would need to be a new layer to style correctly,
+and other such 'decorations' could be considered.
+(currently, bins, park-benches, etc are considered regular POI while these
+would fit in their own 'low-rank' category)

+style snippet by adding new style layer so the changes are propagated visually into the style.
+All new style layers must have the `order` value which determines the order or rendering in the map style. 
+After the layer style snippet is modified run:
+```bash
+make build-style
+```
+
+
+
 Now you are ready to **generate the vector tiles**. By default, `./.env` specifies the entire planet BBOX for zooms 0-7, but running `generate-bbox-file` will analyze the data file and set the `BBOX` param to limit tile generation.
 
 ```
-make generate-bbox-file  # compute data bbox -- not needed for the whole planet
+make generate-bbox-file  # compute data bbox -- not needed for the whole planet or for downloaded area by `make download`
-make generate-tiles      # generate tiles
+make generate-tiles-pg   # generate tiles
 ```
 
+### Workflow to generate tiles
+If you go from top to bottom you can be sure that it will generate a .mbtiles file out of a .osm.pbf file
+```
+make clean                  # clean / remove existing build files
+make                        # generate build files
+make start-db               # start up the database container.
+make import-data            # Import external data from OpenStreetMapData, Natural Earth and OpenStreetMap Lake Labels.
+make download area=albania  # download albania .osm.pbf file -- can be skipped if a .osm.pbf file already existing
+make import-osm             # import data into postgres
+make import-wikidata        # import Wikidata
+make import-sql             # create / import sql functions 
+make generate-bbox-file     # compute data bbox -- not needed for the whole planet or for downloaded area by `make download`
+make generate-tiles-pg      # generate tiles
+```
+Instead of calling `make download area=albania` you can add a .osm.pbf file in the `data` folder `openmaptiles/data/your_area_file.osm.pbf`
+
+To change the name of the output filename, you can modify the variable `MBTILES_FILE` in the `.env` file or set up the environment variable `MBTILES_FILE` before running `./quickstart.sh` or `make generate-tiles-pg` (e.g., `MBTILES_FILENAME=monaco.mbtiles ./quickstart.sh monaco`).

+# OpenMapTiles SQL Testing
+
+The OpenMapTiles SQL tests ensure that OSM data is properly imported and updated in the OpenMapTiles data schema.  The tests work by injecting test OSM data into the database and checking to ensure that the data is properly reflected in the SQL output. 
+
+Usage:
+
+`make clean && make test-sql`
+
+## How it works
+
+The SQL tests consist of the following parts:
+
+ 1. **Test import data**, located in `tests/import`.  This test data is in the [OSM XML](https://wiki.openstreetmap.org/wiki/OSM_XML) format and contains the data that should be initially injected into the database.  The files are numbered in order to ensure that each test data file OSM id numbers that are unique from the other files.  For example, the file starting with `100` will use node ids from 100000-199999, way ids from 1000-1999, and relation ids from 100-199.
+ 2. **Test update data**, located in `tests/update`.  This test data is in the [osmChange XML](https://wiki.openstreetmap.org/wiki/OsmChange) format, and contains the data that will be used to update the test import data (in order to verify that the update process is working correctly.  These files are also numbered using the same scheme as the test import data.
+ 3. **Import SQL test script**, located at `tests/test-post-import.sql`.  This script is executed after the test import data has been injected, and runs SQL-based checks to ensure that the import data was properly imported.  If there are failures in the tests, an entry will be added to the table `omt_test_failures`, with one record per error that occurs during the import process.  A test failure will also fail the build.  To inspect the test failure messages, run `make psql` and issue the comment `SELECT * FROM omt_test_failures`.
+ 4. **Update SQL test script**, located at `tests/test-post-update.sql`.  This script performs the same function as the import test script, except that it occurs after the test update data has been applied to the database.  Note that script will only run if the import script passes all tests.

-# Keep the vector tiles updated
+# Keeping the Vector Tiles Updated
 
 Once you have imported OpenMapTiles you can also keep it up to date by importing the latest OSM changes and
 regenerating the tables.
 
 ## Import
 
-You can either keep the database up to date based on the daily OSM change feed
+You can either keep the database up to date based on the daily (or minutely) OSM change feed
 or import specific change files.
 
+### Choosing the Download Source
+
+While GeoFabrik currently provides extracts of basically all countries, they provide only daily updates.
+If you need minutely updates you might want to try openstreetmap.fr, for example like this: `make download-osmfr area=africa/eritrea`, which configures minutely updates.
+
+### Preparations
+
+If you plan to keep data updated automatically, before importing any data, make sure to set
+
+```
+DIFF_MODE=true
+```
+
+in the `.env`
+
+Now download fresh data:
+
+```
+make download area=your-area-of-choice
+```
+
 ### Keep Database Updated
 
-You can use the new imposm3 feature to keep the database updated (thanks to the [work by @stirringhalo](https://github.com/openmaptiles/openmaptiles/pull/131)). This will automatically download
+You can use imposm3 to keep the database updated (thanks to the [work by @stirringhalo](https://github.com/openmaptiles/openmaptiles/pull/131)).
-the OSM change feed and import it into the database.
+This will repeatedly download the OSM change feed and import it into the database.
-After each run you should also have a list of tiles that have updated.
+In order to be able to update the database, the initial download and import of the OSM data must be done when `DIFF_MODE=true` is set in the `.env` file.
+In this mode the initial download also sets the update source and the update intervals.
+
+To start the update process please use
+```
+make start-update-osm
+```
+
+To stop the update process please use
+```
+make stop-update-osm
+```
+
+After each update activation, **imposm3** will store lists of updated tiles in text format in subfolders of the `diffdir`,
+named for the date(s) on which the import took place (`YYYYMMDD`).
+
+See [Generate Changed Tiles](#generate-changed-tiles) below on how this file can be used.
+
+#### Note
+When the update process is actively updating the DB it is impossible to successfully generate tiles,
+as there will be conflicts and deadlocks related to the DB access.
+
+Unfortunately, there is no known way to execute an external command in-between rounds of the `update-osm` process.
+
+#### Troubleshooting
+
+The log file for osm update can be viewed using
 
 ```
-make update-osm
+docker-compose logs --tail 100 --follow update-osm
+```
+
+Use `Ctrl-C` to stop following the log.
+
+The output will be similar to this:
+
+```
+[info] Importing #4889572 including changes till ....... +0000 UTC (2h10m10s behind)
+```
+
+It might take some time to catch up with the latest changes, but the "time behind" should decrease until it is a few minutes.
+If it doesn't, you need to download a new extract or check that there are enough system resources to keep-up with the changes.
+
+Finally you will get an output like this - this indicates, that some 6 objects were changed:
+
+```
+[progress]     3s C:       0/s (0) N:       0/s (0) W:       0/s (6) R:      0/s (0)
+```
+
+The process will keep running foreverprint something like this - which just means that no changes were in the latest changeset:
+
+```
+[progress]     0s C:       0/s (0) N:       0/s (0) W:       0/s (0) R:      0/s (0)
 ```
 
 ### Import Change File
 
-Given you have a file `changes.osc.gz` in your import folder. Once you ran the import command you should also have a list of tiles that have updated.
+You may perform a one-time import of OSM changes from the `changes.osc.gz` file in your import folder using
 
 ```
 make import-diff
 ```
 
+Similar to[Keep Database Updated](#keep_database_updated) above, **imposm3** will store the list of updated tiles in text file in subfolders of the `diffdir`,
+named for the date on which the import took place (`YYYYMMDD`).
+
+See [Generate Changed Tiles](#generate-changed-tiles) below.
+
+#### Note
+There is no `make` command for downloading OSM changes into `changes.osc.gz`.
+You may perform this task using [`osmupdate`](https://wiki.openstreetmap.org/wiki/Osmupdate),
+[pyosmium-get-changes](https://docs.osmcode.org/pyosmium/latest/tools_get_changes.html),
+or downloading the changefile directly from the replication server.
+
 ## Generate Changed Tiles
 
-After the import has finished **imposm3** will store lists of tiles in text format in subfolders of the `diffdir`,
+To generate all changed tiles, based on the lists of all updated tiles, and update the existing MBtiles file, please use
-named for the date(s) on which the import took place (`YYYYMMDD`).
-Copy and merge the files to `tiles.txt` in the import folder (`data`), either manually or with the following command, which also removes duplicate tiles so they are only generated once:  
-```
-cd data && sort ./*/*.tiles | uniq > tiles.txt
-```
-
-Now run the command to read the tilelist and write the vector tiles for it to a new MBTiles.
 
 ```
-docker-compose run generate-changed-vectortiles
+make generate-changed-tiles
