+## Example mvt_postgis and map config for SRID 4326
+
+When using a 4326 projection with ST_AsMVT the SQL statement needs to be modified. ST_AsMVTGeom is expecting data in 3857 projection so the geometries and the `!BBOX!` token need to be transformed prior to `ST_AsMVTGeom` processing them. For example:
+
+```toml
+[[providers]]
+name = "test_postgis"
+type = "mvt_postgis"
+host = "localhost"
+port = 5432
+database = "tegola"
+user = "tegola"
+password = ""
+srid = 4326 # setting the srid on the provider to 4326 will cause the !BBOX! value to use the 4326 projection.
+
+  [[providers.layers]]
+  name = "landuse"
+  # the !BBOX! token used in the WHERE clause is not reprojected so it can match 4326 data
+  # the matched data AND the !BBOX! are then reporojected to 3857 prior to being passed to ST_AsMVTGeom
+  sql = "SELECT ST_AsMVTGeom(ST_Transform(geom, 3857),ST_Transform(!BBOX!,3857)) AS geom, gid FROM gis.landuse WHERE geom && !BBOX!"

 ## Testing
 
 Testing is designed to work against a live PostGIS database. To see how to set up a database check this [github actions script](https://github.com/go-spatial/tegola/blob/master/.github/worksflows/on_pr_push.yml). To run the PostGIS tests, the following environment variables need to be set:
