+The `GEOADD` command in DiceDB is used to add geospatial items (longitude,latitude) to a specified key, storing them as a sorted set. This would allow for efficient querying of geographical data using commands like GEOSEARCH.
+
+## Syntax
+
+```bash
+GEOADD key [NX | XX] [CH] longitude latitude member [longitude latitude member ...]
+```
+
+## Parameters
+
+| Parameter | Description                                                                       | Type   | Required |
+| --------- | --------------------------------------------------------------------------------- | ------ | -------- |
+| key       | The name of the sorted set where the geospatial data will be stored.              | string | Yes      |
+| NX        | Only add new elements; do not update existing ones.                               | NONE   | No       |

+| longitude | longitude of the location (must be between -180 and 180 degrees).                 | float  | Yes      |
+| latitude  | latitude of the location (must be between -85.05112878 and 85.05112878 degrees).  | float  | Yes      |
+| member    | A unique identifier for the location.                                             | string | Yes      |
+
+
+## Return Values
+
+| Condition                                                    | Return Value                                                |
+| ------------------------------------------------------------ | ----------------------------------------------------------- |
+| For each new member added.                                   | 1                                                           |
+| No new member is added.                                      | 0                                                           |
+| Incorrect Argument Count                                     |`ERR wrong number of arguments for 'geoadd' command`         |
+| If the longitude is not a valid number or is out of range.   |`ERR invalid longitude`                                      |
+| If the latitude  is not a valid number or is out of range.   |`ERR invalid latitude`                                       |
+
+## Behaviour
+
+When the GEOADD command is issued, DiceDB performs the following steps:
+
+1. It checks if argument count is valid or not. If not an error is thrown.
+2. It checks whether optional parameters are applied or not.
+3. It checks whether longitude and latitude are valid or not. If not an error is thrown. 
+3. It checks whether the set exists or not.
+4. If set doesn't exist new set is created or else the same set is used. 
+5. It adds or updates the member in the set.
+6. It returns number of members added. 
+
+## Errors
+
+1.`Wrong number of arguments for 'GEOADD' command`
+   - Error Message: (error) ERR wrong number of arguments for 'geoadd' command.
+   - Occurs when the command is executed with an incorrect number of arguments.
+
+2. `Longitutde not a valid number or is out of range `
+   - Error Message: (error) ERR invalid longitude.
+   - Occurs when longitude is out of range(-180 to 180) or not a valid number.
+
+3. `Latitdude not a valid number or is out of range `
+   - Error Message: (error) ERR invalid latitude.
+   - Occurs when latitude is out of range(-85.05112878 to 85.05112878) or not a valid number.
+
+## Example Usage
+
+Here are a few examples demonstrating the usage of the GEOADD command:
+
+### Example 1: Adding new member to a set
+
+```bash
+127.0.0.1:7379> GEOADD locations 13.361389 38.115556 "Palermo"
+1
+```
+
+### Example 2: Updating an already existing member to a set
+
+```bash
+127.0.0.1:7379> GEOADD locations 13.361389 39.115556 "Palermo"
+0
+```
+
+### Example 3: Error Adding a member with invalid longitude
+
+```bash
+127.0.0.1:7379> GEOADD locations 181.120332 39.115556 "Jamaica"
+(error) ERROR invalid longitude
+```
+
+### Example 4: Error Adding a member with invalid latitde
+
+```bash
+127.0.0.1:7379> GEOADD locations 13.361389 91.115556 "Venice"
+(error) ERROR invalid latitude
+```

+3. It gets the scores(geohashes) from the sorted sets for both the members.
+4. It calculates the distance bw them and returns it.
