+## Import OpenStreetMap data
+
+**Hint:** This step may be skipped if you are using [Lean mode](./docs/lean-mode.md).
+
+You need to import road information from OpenStreetMap for the portal to work.
+This information is stored in your PostgreSQL database and used when processing
+tracks (instead of querying the Overpass API), as well as for vector tile
+generation. The process applies to both development and production setups. For
+development, you should choose a small area for testing, such as your local
+county or city, to keep the amount of data small. For production use you have
+to import the whole region you are serving.
+
+* Install `osm2pgsql`. 
+* Download the area(s) you would like to import from [GeoFabrik](https://download.geofabrik.de). 
+* Import each file like this:
+
+    ```bash
+    osm2pgsql --create --hstore --style roads_import.lua -O flex \
+      -H localhost -d obs -U obs -W \
+      path/to/downloaded/myarea-latest.osm.pbf 
+    ```
+
+You might need to adjust the host, database and username (`-H`, `-d`, `-U`) to
+your setup, and also provide the correct password when queried. For the
+development setup the password is `obs`. For production, you might need to
+expose the containers port and/or create a TCP tunnel, for example with SSH,
+such that you can run the import from your local host and write to the remote
+database.
+
+The import process should take a few seconds to minutes, depending on the area
+size. A whole country might even take one or more hours. You should probably
+not try to import `planet.osm.pbf`. 
+
+You can run the process multiple times, with the same or different area files,
+to import or update the data. However, for this to work, the actual [command
+line arguments](https://osm2pgsql.org/doc/manual.html#running-osm2pgsql) are a
+bit different each time, including when first importing, and the disk space
+required is much higher. 
+
+Refer to the documentation of `osm2pgsql` for assistance. We are using "flex
+mode", the provided script `roads_import.lua` describes the transformations
+and extractions to perform on the original data.

 # Upgrading
+
 This document describes the general steps to upgrade between major changes.
 Simple migrations, e.g. for adding schema changes, are not documented
 explicitly. Their general usage is described in the [README](./README.md) (for
-development) and [docs/production-deployment.md](docs/production-deployment.md) (for production).
-
-
-## 0.8.1
- 
- Get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
- Rebuild images ``docker-compose build``
- No database upgrade is required, but tile functions need an update:
-  ```bash
-  docker-compose run --rm portal tools/prepare_sql_tiles.py
-  ```
- Start your portal and worker services. ``docker-compose up -d worker portal``
-
-
-## 0.8.0
-Upgrade to `0.7.x` first. See below for details. Then follow these steps:
-
-> **Warning** The update includes a reprocessing of tracks after import. Depending on the number of tracks this can take a few hours. The portal is reachable during that time but events disappear and incrementally reappear during reimport.
-
-> **Info** With this version the import process for OpenStreetMap data has changed: the [new process](docs/osm-import.md) is easier on resources and finally permits to import a full country on a low-end VM.
-
- Do your [usual backup](docs/production-deployment.md)
- get the release in your source folder (``git pull; git checkout 0.8.0`` and update submodules ``git submodule update --recursive``)
- Rebuild images ``docker-compose build``
- Stop your portal and worker services ``docker-compose stop worker portal``
- run upgrade
-  ```bash
-  docker-compose run --rm portal tools/upgrade.py
-  ```
-  this automatically does the following
-  - Migration of database schema using alembic.
-  - Upgrade of SQL tile schema to new schema.
-  - Import the nuts-regions from the web into the database.
-  - Trigger a re-import of all tracks.
- Start your portal and worker services. ``docker-compose up -d worker portal``

+# Lean mode
+
+The application can be configured in "lean mode" through the `LEAN_MODE`
+setting in `config.py`. A lean installation is easier to set up, as a few steps
+can be skipped. However, the performance of the application will degrade in
+lean mode, and lots of advanced features will not be available.
+
+Lean mode is meant as an entrypoint to get started with collecting data,
+without the hassle of importing and maintaining OpenStreetMap data.
+
+## Disabled features in lean mode
+
+* No map tiles are generated.
+* The frontend will not show an overview map, only per-track maps.
+* The `roads` database table is not used, neither for processing tracks, nor
+  for generating map tiles.
+* The API will not generate auxiliary information for display on the
+  (nonexistent) map, such as per-road statistics.
+
+## Switch to/from lean mode 
+
+To enable lean mode, set the following in your `config.py` (or in
+`config.overrides.py`, especially in development setups):
+
+```python
+LEAN_MODE = True
+```
+
+To disable lean mode, set it to `False` instead.
+
+For lean mode, it is important that the config variable `OBS_FACE_CACHE_DIR` is
+properly set, or that you are happy with its default value of using
+`$DATA_DIR/obs-face-cache`.
+
+When turning off lean mode, make sure to fill your `roads` table properly, as
+otherwise the track processing will not work. When turning on lean mode, you
+may truncate the `roads` table to save space, but you don't need to, it simply
+becomes unused.
+
+## Benefits
+
+* When using lean mode, you can skip the import of OpenStreetMap data during
+  setup, and you also do not need to keep it updated. 
+* People can already start uploading data and the data is also processed,
+  giving you as a maintainer more time to set up the full application, if you
+  want to.
+
+## Drawbacks
+
+* Lean mode is less performant when processing tracks.
+* Lean mode track processing depends on the Overpass API data source, which may
+  be slow, unavailable, or rate limiting the requests, so processing may fail.
+  We use caching to prevent some issues, but as we depend on a third party
+  service here that is accessed for free and that generates a lot of server
+  load, we really can't ask for much. If you frequently run into issues, the
+  best bet is to manage OSM data yourself and turn off lean mode.
+* Of course some features are missing.

-# Importing OpenStreetMap data
-
-The application requires a lot of data from the OpenStreetMap to work.
-
-The required information is stored in the PostgreSQL database and used when
-processing tracks, as well as for vector tile generation. The process applies
-to both development and production setups. For development, you should choose a
-small area for testing, such as your local county or city, to keep the amount
-of data small. For production use you have to import the whole region you are
-serving.
-
-## General pipeline overview
-
-1. Download OpenStreetMap data as one or more `.osm.pbf` files.
-2. Transform this data to generate geometry data for all roads and regions, so
-   we don't need to look up nodes separately. This step requires a lot of CPU
-   and memory, so it can be done "offline" on a high power machine.
-3. Import the transformed data into the PostgreSQL/PostGIS database.
-
-## Community hosted transformed data
-
-Since the first two steps are the same for everybody, the community will soon
-provide a service where relatively up-to-date transformed data can be
-downloaded for direct import. Stay tuned.
-
-## Download data
-
-[GeoFabrik](https://download.geofabrik.de) kindly hosts extracts of the
-OpenStreetMap planet by region. Download all regions you're interested in from
-there in `.osm.pbf` format, with the tool of your choice, e. g.:
-
-```bash
-wget -P local/pbf/ https://download.geofabrik.de/europe/germany/baden-wuerttemberg-latest.osm.pbf 
-```
-
-## Transform data
-
-To transform downloaded data, you can either use the docker image from a
-development or production environment, or locally install the API into your
-python environment. Then run the `api/tools/transform_osm.py` script on the data.
-
-```bash
-api/tools/transform_osm.py baden-wuerttemberg-latest.osm.pbf baden-wuerttemberg-latest.msgpack
-```
-
-In dockerized setups, make sure to mount your data somewhere in the container
-and also mount a directory where the result can be written. The development
-setup takes care of this, so you can use:
-
-```bash
-docker-compose run --rm api tools/transform_osm.py \
-  /pbf/baden-wuerttemberg-latest.osm.pbf /obsdata/baden-wuerttemberg-latest.msgpack
-```
-
-Repeat this command for every file you want to transform.
-
-## Import transformed data
-
-The command for importing looks like this:
-
-```bash
-api/tools/import_osm.py baden-wuerttemberg-latest.msgpack
-```
-
-This tool reads your application config from `config.py`, so set that up first
-as if you were setting up your application.
-
-In dockerized setups, make sure to mount your data somewhere in the container.
-Again, the development setup takes care of this, so you can use:
-
-```bash
-docker-compose run --rm api tools/import_osm.py \
-  /obsdata/baden-wuerttemberg-latest.msgpack
-```
-
-The transform process should take a few seconds to minutes, depending on the area
-size. You can run the process multiple times, with the same or different area
-files, to import or update the data. You can update only one region and leave
-the others as they are, or add more filenames to the command line to
-bulk-import data.
-
-## How this works
-
-* The transformation is done with a python script that uses
-  [pyosmium](https://osmcode.org/pyosmium/) to read the `.osm.pbf` file. This
-  script then filters the data for only the required objects (such as road
-  segments and administrative areas), and extracts the interesting information
-  from those objects.
-* The node geolocations are looked up to generate a geometry for each object.
-  This requires a lot of memory to run efficiently.
-* The geometry is projected to [Web Mercator](https://epsg.io/3857) in this
-  step to avoid continous transformation when tiles are generated later. Most
-  operations will work fine in this projection. Projection is done with the
-  [pyproj](https://pypi.org/project/pyproj/) library.
-* The output is written to a binary file in a very simple format using
-  [msgpack](https://github.com/msgpack/msgpack-python), which is way more
-  efficient that (Geo-)JSON for example. This format is stremable, so the
-  generated file is never fully written or read into memory.
-* The import script reads the msgpack file and sends it to the database using
-  [psycopg](https://www.psycopg.org/). This is done because it supports
-  PostgreSQL's `COPY FROM` statement, which enables much faster writes to the
-  database that a traditionional `INSERT VALUES`. The file is streamed directly
-  to the database, so it is never read into memory.
