+## Build process
+
+To build your own version of the package, you need to have Python 3.7+ installed.
+Then, after optionally creating a virtual environment, run the following command
+from the repository root to install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+Then, run the following command to build the database:
+
+```bash
+$ python build_db.py
+...
+$ python add_placename_data.py
+...
+```
+
+This creates an SQLite3 database in the repo root named `iceaddr.db`. Move this file to
+`iceaddr/resources/` and you can now install your own version of the package:
+
+```bash
+python setup.py install
+```
+
 ## Version History
 
 * 0.5.5: Updated address and placename data. Removed ISN93 coords. Now requires Python 3.7+ (11/12/2022)

 TODO for iceaddr
 
+* Provide placenames and street names in all cases (nf, þf, þgf, ef)
 * Verify that GPS coordinates are rational in DB build process
 * Better automation of geo data processing in db build scripts, should not be a separate step
 * iceaddr_suggest relies on comma separator to separate street address and place name. Could be made smarter.
