-```
 
-For in-place snapshot in database

-```bash
+    make build

+> **Note:** previous versions of this service used different variable names. To update, change the following:
+> * `LVL_DB_PATH`, `LEVELDB_PATH` => `ETHDB_PATH`
+> * `ANCIENT_DB_PATH`, `LEVELDB_ANCIENT` => `ETHDB_ANCIENT`
+> * `LOGRUS_LEVEL`, `LOGRUS_FILE` => `LOG_LEVEL`, `LOG_FILE`, etc.
+
+
+## Usage
+
+* For state snapshot from EthDB:
+
+    ```bash
+    ./ipld-eth-state-snapshot stateSnapshot --config={path to toml config file}
+    ```
+
+    * Account selective snapshot: To restrict the snapshot to a list of accounts (addresses), provide the addresses in config parameter `snapshot.accounts` or env variable `SNAPSHOT_ACCOUNTS`. Only nodes related to provided addresses will be indexed.
+
+        Example:
+
+        ```toml
+        [snapshot]
+            accounts = [
+                "0x825a6eec09e44Cb0fa19b84353ad0f7858d7F61a"
+            ]
+        ```
+
+## Monitoring
+
+* Enable metrics using config parameters `prom.metrics` and `prom.http`.
+* `ipld-eth-state-snapshot` exposes following prometheus metrics at `/metrics` endpoint:
+    * `state_node_count`: Number of state nodes processed.
+    * `storage_node_count`: Number of storage nodes processed.
+    * `code_node_count`: Number of code nodes processed.
+    * DB stats if operating in `postgres` mode.
+
 ## Tests
 
-* Install [mockgen](https://github.com/golang/mock#installation)
+* Run unit tests:
-* `make test`
+
+    ```bash
+    # setup db
+    docker-compose up -d
+
+    # run tests after db migrations are run
+    make dbtest
+
+    # tear down db
+    docker-compose down -v --remove-orphans
+    ```
+
+## Import output data in file mode into a database
+
+* When `ipld-eth-state-snapshot stateSnapshot` is run in file mode (`database.type`), the output is in form of CSV files.
+
+* Assuming the output files are located in host's `./output_dir` directory.
+
+* Data post-processing:
+
+    * Create a directory to store post-processed output:
+
+        ```bash
+        mkdir -p output_dir/processed_output
+        ```
+
+    * Combine output from multiple workers and copy to post-processed output directory:
+
+        ```bash
+        # ipld.blocks
+        cat {output_dir,output_dir/*}/ipld.blocks.csv > output_dir/processed_output/combined-ipld.blocks.csv
+
+        # eth.state_cids
+        cat output_dir/*/eth.state_cids.csv > output_dir/processed_output/combined-eth.state_cids.csv
+
+        # eth.storage_cids
+        cat output_dir/*/eth.storage_cids.csv > output_dir/processed_output/combined-eth.storage_cids.csv
+
+        # public.nodes
+        cp output_dir/public.nodes.csv output_dir/processed_output/public.nodes.csv
+
+        # eth.header_cids
+        cp output_dir/eth.header_cids.csv output_dir/processed_output/eth.header_cids.csv
+        ```
+
+    * De-duplicate data:
+
+        ```bash
+        # ipld.blocks
+        sort -u output_dir/processed_output/combined-ipld.blocks.csv -o output_dir/processed_output/deduped-combined-ipld.blocks.csv
+
+        # eth.header_cids
+        sort -u output_dir/processed_output/eth.header_cids.csv -o output_dir/processed_output/deduped-eth.header_cids.csv
+
+        # eth.state_cids
+        sort -u output_dir/processed_output/combined-eth.state_cids.csv -o output_dir/processed_output/deduped-combined-eth.state_cids.csv
+
+        # eth.storage_cids
+        sort -u output_dir/processed_output/combined-eth.storage_cids.csv -o output_dir/processed_output/deduped-combined-eth.storage_cids.csv
+        ```
+
+* Copy over the post-processed output files to the DB server (say in `/output_dir`).
+
+* Start `psql` to run the import commands:
+
+    ```bash
+    psql -U <DATABASE_USER> -h <DATABASE_HOSTNAME> -p <DATABASE_PORT> <DATABASE_NAME>
+    ```
+
+* Run the following to import data:
+
+    ```bash
+    # public.nodes
+    COPY public.nodes FROM '/output_dir/processed_output/public.nodes.csv' CSV;
+
+    # ipld.blocks
+    COPY ipld.blocks FROM '/output_dir/processed_output/deduped-combined-ipld.blocks.csv' CSV;
+
+    # eth.header_cids
+    COPY eth.header_cids FROM '/output_dir/processed_output/deduped-eth.header_cids.csv' CSV;
+
+    # eth.state_cids
+    COPY eth.state_cids FROM '/output_dir/processed_output/deduped-combined-eth.state_cids.csv' CSV FORCE NOT NULL state_leaf_key;
+
+    # eth.storage_cids
+    COPY eth.storage_cids FROM '/output_dir/processed_output/deduped-combined-eth.storage_cids.csv' CSV FORCE NOT NULL storage_leaf_key;
+    ```
+
+* NOTE: `COPY` command on CSVs inserts empty strings as `NULL` in the DB. Passing `FORCE_NOT_NULL <COLUMN_NAME>` forces it to insert empty strings instead. This is required to maintain compatibility of the imported snapshot data with the data generated by statediffing. Reference: https://www.postgresql.org/docs/14/sql-copy.html
+
+### Troubleshooting
+
+* Run the following command to find any rows (in data dumps in `file` mode) having unexpected number of columns:
+
+    ```bash
+    ./scripts/find-bad-rows.sh -i <input-file> -c <expected-columns> -o [output-file] -d true
+    ```
+
+* Run the following command to select rows (from data dumps in `file` mode) other than the ones having unexpected number of columns:
+
+    ```bash
+    ./scripts/filter-bad-rows.sh -i <input-file> -c <expected-columns> -o <output-file>
+    ```
+
+* See [scripts](./scripts) for more details.

+## Data Validation
+
+* For a given table in the `ipld-eth-db` schema, we know the number of columns to be expected in each row in the data dump:
+
+  | Table              | Expected columns |
+  |--------------------|:----------------:|
+  | `public.nodes`     | 5                |
+  | `ipld.blocks`      | 3                |
+  | `eth.header_cids`  | 16               |
+  | `eth.state_cids`   | 8                |
+  | `eth.storage_cids` | 9                |
+
+### Find Bad Data
+
+* Run the following command to find any rows having unexpected number of columns:
+
+  ```bash
+  ./scripts/find-bad-rows.sh -i <input-file> -c <expected-columns> -o [output-file] -d [include-data]
+  ```
+
+  * `input-file` `-i`: Input data file path
+  * `expected-columns` `-c`: Expected number of columns in each row of the input file
+  * `output-file` `-o`: Output destination file path (default: `STDOUT`)
+  * `include-data` `-d`: Whether to include the data row in the output (`true | false`) (default: `false`)
+  * The output is of format: row number, number of columns, the data row
+
+    Eg:
+
+    ```bash
+    ./scripts/find-bad-rows.sh -i eth.state_cids.csv -c 8 -o res.txt -d true
+    ```
+
+    Output:
+
+    ```
+    1 9 1500000,xxxxxxxx,0x83952d392f9b0059eea94b10d1a095eefb1943ea91595a16c6698757127d4e1c,,baglacgzasvqcntdahkxhufdnkm7a22s2eetj6mx6nzkarwxtkvy4x3bubdgq,\x0f,0,f,/blocks/,DMQJKYBGZRQDVLT2CRWVGPQNNJNCCJU7GL7G4VAI3LZVK4OL5Q2ARTI
+    ```
+
+    Eg:
+
+    ```bash
+    ./scripts/find-bad-rows.sh -i public.nodes.csv -c 5 -o res.txt -d true
+    ./scripts/find-bad-rows.sh -i ipld.blocks.csv -c 3 -o res.txt -d true
+    ./scripts/find-bad-rows.sh -i eth.header_cids.csv -c 16 -o res.txt -d true
+    ./scripts/find-bad-rows.sh -i eth.state_cids.csv -c 8 -o res.txt -d true
+    ./scripts/find-bad-rows.sh -i eth.storage_cids.csv -c 9 -o res.txt -d true
+    ```
+
+## Data Cleanup
+
+* In case of column count mismatch, data from `file` mode dumps can't be imported readily into `ipld-eth-db`.
+
+### Filter Bad Data
+
+* Run the following command to filter out rows having unexpected number of columns:
+
+  ```bash
+  ./scripts/filter-bad-rows.sh -i <input-file> -c <expected-columns> -o <output-file>
+  ```
+
+  * `input-file` `-i`: Input data file path
+  * `expected-columns` `-c`: Expected number of columns in each row of the input file
+  * `output-file` `-o`: Output destination file path
+
+    Eg:
+
+    ```bash
+    ./scripts/filter-bad-rows.sh -i public.nodes.csv -c 5 -o cleaned-public.nodes.csv
+    ./scripts/filter-bad-rows.sh -i ipld.blocks.csv -c 3 -o cleaned-ipld.blocks.csv
+    ./scripts/filter-bad-rows.sh -i eth.header_cids.csv -c 16 -o cleaned-eth.header_cids.csv
+    ./scripts/filter-bad-rows.sh -i eth.state_cids.csv -c 8 -o cleaned-eth.state_cids.csv
+    ./scripts/filter-bad-rows.sh -i eth.storage_cids.csv -c 9 -o cleaned-eth.storage_cids.csv
