 1. I began by downloading the data from the NIJ [site](https://www.nij.gov/funding/pages/fy16-crime-forecasting-challenge.aspx#data)
 2. Since the data was in .xlsx I used $ in2csv to convert the excel files to csv
 3. Using $ csvsql I created table schemas for each csv (all years 2012-2015, then 4 csvs for 2016 so far). SQL for the basic schema was as follows
-```

 4. I imported data for each csv into the postgres db on the EC2 instance using the psql \COPY function. This [link](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL.Procedural.Importing.html) was helpful.
 
-```
-$psql target-db \
-  -U <admin user> \ 
-  -p <port> \ 
-  -h <DB instance name> \ 
-  -c "\copy source-table from 'source-table.csv' (FORMAT CSV, HEADER)"
-  ```

+        -c "\copy source-table from 'source-table.csv' (FORMAT CSV, HEADER)"

 5. I then used INSERT INTO to append data to the crimes table
-```
-INSERT INTO nij.crimes
-  (category,
-  call_group,
-  final_case_type,
-  case_desc,
-  occ_date,
-  x_coordinate,

-SELECT
-  category,
-  call_group,
-  final_case_type,
-  case_desc,
-  occ_date,
-  x_coordinate,
-  y_coordinate,
-  census_tract
-FROM nij.nij_2015;
-```
+    ```
+    INSERT INTO nij.crimes
+      (category,
+      call_group,
+      final_case_type,
+      case_desc,

+      x_coordinate,
+      y_coordinate,
+      census_tract)

+      category,
+      call_group,
+      final_case_type,
+      case_desc,
+      occ_date,
+      x_coordinate,
+      y_coordinate,
+      census_tract
+    FROM nij.nij_2015;
